- Here’s what’s inside a Volkswagen Diesel engine and how it works!
In this video, Volkswagen turbo diesel BRM engine from a 2006 Jetta TDI with 295,000km on it is torn down. Diesel engines have some major differences in operation and composition than gasoline engines. They are the most thermally efficient engine, despite the controversy surrounding its emissions. Diesel engines provide a lot of torque, which is why it is found in many heavier duty applications besides VW/Audi passenger cars.
Diesel engines vary in operation from gasoline engines in that their combustion is controlled by compression, rather than ignition. Air is compressed as the piston moves up within the cylinder and then fuel is injected near the top. The resulting high pressure and temperature causes the fuel to atomize and combust, without the need for an ignition source, such as a spark plug. Glow plugs are used only when the air temperature is very cold to help start the engine. The resulting combustion is uncontrolled and pushes the piston down, creating work to rotate the crankshaft. Piston heads have a small crater in the top to allow the fuel to be directly injected when the piston is at top center.
The amount of combustion and thus engine speed is controlled by how much fuel is injected into the cylinder, as opposed to a gasoline engine which uses a throttle body to control the amount of air. Thus, diesel engines benefit from a higher compression and by running lean using a turbocharger to force more air into the combustion chamber, and don’t need a throttle body during regular operation.

Those injectors are VERY expensive and valuable on the secondhand market. If you can clean them up and verify operation, they could be worth several hundred dollars as a set.
Thanks for letting me know... if you'd like to buy them off me.. otherwise it's going in the pile lol
I like that plastic cover on that harmonic balancer (it prevents water from getting at the bolts underneath it). Whoever was on the hammock is now a witness to your crimes against other people's old stuff (toothbrush, rags, etc), LOL!
The wife in the hammock lol
Great vid as per usual! Here's a bit of trivia if someone's interested. The 1.9 started its life as the early 90s L5 2.5 TDI, they pretty much just cut off a cylinder. The goes to the L3 1.4 TDI, in which they cut off another cylinder making it a 3 banger. The bore and stroke are exactly the same across all engines.
They come standard with forged internals, hence their heft. Forged pistons, forged conrods and forged crankshaft.
Here in Europe they're some of the most sought after engines in the tuning scene as you can easily and fairly reliably double WHP for under 1000$. Plus, they're very fuel efficient returning more than 6L/100km or about 35 mpg. Even when tuned they return very good fuel consumption.
You definitely pay a premium for them despite them being really common. Parts are on the cheaper side and you can even buy a brand new block with pistons from VW for about €600. At a junkyard you can get complete engines with turbos for around €800. They're a very common engine swap given how much support there is for them.
They're very responsive given their small variable geometry turbo but they really do not like to rev. The older Verteilerpumpe ones (mechanical pump) are more rev happy but revving any TDI past 3.5K feels like revving a gasoline engine past 8K rpm. Past 4.5K feels like the engine is going to grenade itself.
Obviously they have their common failures: MAF is a chronical one and on the PDs, the camshaft is a common one as well but other than that, there's the odd cylinder head developing cracks on the earlier PD engines but not much more about it. I'm no mechanic but we've owned several 1.9s, both VP and PD and we've never had any issue other than the MAF failing or an odd boost pipe just falling off lol. Combined, our TDIs covered more than 1,000,000km 😁 the first we owned was in the mid 90s, an 1Z, we then owned an AFN from 2000 to 2020 and now we have my AJM PD mk4. You can definitely feel that the PDs are way more torquier, but you can't beat the sound of a VP TDI. Especially the AFN, it just sounds absolutely fantastic. All in all, trouble free motoring, really. Parked for a month? No problem, just turn the key and it'll come to life right up :) but let's not get started about those pesky vw electrical gremlins...
I have a 2003 beetle 1.9 tdi PD100 (ATD)
They’re bullet proof engines.
In fact just had a new cam belt, water pump and Aux belt and tensioner done today.
I get about 40 mpg urban and 55 plus motorway 👌🏼👌🏼
It’s covered just 111k miles
@@Dan23_7 you're making me jelly! A sub 120k mile 1.9 TDI is a mirage these days and being on a Bug is the icing on the cake. Happy motoring mate, cheers 👍😀
@@Dan23_7 also, very fun to think of an engine at around 120k miles as being barely broken in while others barely make it to 60k miles lol
I have a '98 Jetta with the AHU TDI and VE pump. The engine made it 500,000 miles without any major issues.
I will be taking it apart to diagnose a compression issue that is causing a misfire.
I am amazed how clean the engine internals look and how little visible wear there is on this half a million mile engine that has never been apart. Even the original turbo survived the 500K miles of use.
Another impressive thing was the compression readings on 3 out of 4 cylinders was at full maximum spec of 450psi.
Very well built engines that do make lots of fun torque. I wish I go into the TDI cars sooner.
@@jonytube thanks mate, yep it makes me smile, and it’s yellow too
A basic cross intersection in Romania has (ofcourse) 4 corners. But there's a known-story that on every cross intersection you can find at least 5 TDIs parked on the corners only. That's how common they are in Eastern Europe.
Wow
I had 3 VW Jetta diesels. The first was a disaster. It was 1986 automatic, found out that it had been used as a taxi in Quebec. The main issue with this one was the placement of the starter, which was directly below the exhaust manifold which caused the starter to fail. The last one was a 2002 Jetta TDI, great car and fantastic fuel economy. It lasted 375,000 till it was written off in an accident.
600k km (400k miles) is not unheard of. I am surprised how small the engine is. And it is the first time I saw such piston. Good video, filled few gaps in my knowledge.
I have one with 550 000 km, car bought new back in 2005. Not a single repair was done until now, not even a cleanup of the intake and it still runs pretty good. Not the most refined (far from it), but these PD engines have a characteristic "brutal" pull that you will not get in any other engine. Before scrapping it (mostly due to the age of the car) I promised myself to do a complete engine teardown to see how the internals look.
I drove this car before I scrapped it. It sure did pull like a train! But they don't like to be revved at all
@@speedkar99 The vacuum pumps on diesel engines is not because of the turbo, it is because the engine does not make vacuum as its intake is unrestricted, no throttle on a diesel.
Also, the lifters do not wear through on these engines, it is the cams and high pressure pumps that see the wear. Lots of misinformation in your video.
Before you make a video explaining how a diesel engine works, you might want to learn for yourself first.
@@davidparker9676 Speedkar is a VW hater, he'll spread misinformation about VW at every opportunity. Oh, and my Turbo petrol GTI has restricted intake, throttle, but still needs a vacuum pump because a turbo engine makes no vacuum by definition.
@@einfelder8262 I know turbo engines don't make vacuum under boost, a gasoline turbo makes plenty of vacuum on closed throttle deceleration when you need it for braking.
Nice! I would love to see more Diesel engines here, especially the ones from Mercedes!
Sure! If I can find them
VW 1.9 TDI was actually a very good engine well before the notorious Dieselgate Scandal. Finding one with a manual transmission is a real gem
1.9TDi where actually not part of the dieselgate thing. They are dirty, but they didn't cheat on those. Newer 1.6L and 2.0L commonrail TDi had that.
Yes the manual did well. The DSG that was hooked to this engine in particular was already failing, hence I decommissioned it
@@speedkar99 great video 👍🏻, in Europe 90% of 1.9TDI are manual, and easy do 500k km and more, this TDI is our workhorse with excellent fuel consumption
I still driving a 1.4tdi (3 cylinder version of 1.9tdi) with great results, 4L/100km
Greetings 👍🏻
@@speedkar99 my wife drove Skoda Octavia with 1.9 tdi PD BKC engine, DQ250 DSG gearbox, after 13 years ECU in mechatronics goes wrong, bought new mechatronics was expensive, but DSG runs like new now.
I've only had Diesel cars (TDIs from VW) for the last 21 years. I've been very satisfied.
Awesome! Besides the issues with the car itself, any issues with the engine?
I had two cars: 1. VW Passat 1.9 TDI 90HP (engine code 1Z) for 11 years (bought when it was 7 years old, sold when it was 18 years old) and 2. VW Tiguan 2.0 TDI 170HP 4Motion (engine code CBBB) for 10.5 years ongoing now (bought when it was 3.5 years old, still owing it at 14 years old)
Passat had two engine issues: a. at 8 years the bolt that kept the crank shaft pulley loosened allowing the pulley to wear a little the shaft's end. This was fixed without taking out the crank shaft by an ingenious lathe mechanic. Never had issues with that after. The second issues was some bad casting in the clutch fork that made it fail at 13 years in a "lightning" pattern. Clutch disc was still original and alive at the next owner when the car was 25 years and 300.000km (186.000 miles) mileage.
Tiguan had throttle body replaced twice (yes, they introduced throttle bodies on Diesels in the mean time) - those are cheap (120$) but nasty as they leave you stranded because they remained stuck closed, a differential sensor for the particulate filter (40$). Also the turbo vacuum capsule failed due to the rubber membrane cracking (200$) at 10 years old. Nothing else engine related.
Your channel is a hidden gem on CZcams. Super interesting!
Good walkthrough. German engineering in the 90s was something else!!
Thanks! It sure is
I’m seriously impressed with your intricate knowledge of mechanics my friend. Just found your channel. I’ve watched enough of your videos today to look for the toothbrush and the random piece of your family’s clothing to soak up oil😂
An excellent video as always.
Thanks
Like for using metric units. And that cam driven injectors are somewhat specific to VW. They are called Pumpe-Düse, high pressure pump and injector in a single unit.
Thanks for that term
This injector type is very common in industrial engines, commonly known as "unit injectors", but they are fairly rare in regular cars.
They went almost straight from mechanical injection, to common rail with piezo controlled injectors, skipping unit injectors.
Canadian
In north america we called them pump douche.
Your narration is spot on and articulate. Love these videos.
Thank you
Very very informative as always
again nice video thank you for your work !
Welcome
Brilliant video as always.
Thanks
Camshaft lobe issues can be prevented pretty much, by doing oil changes every 10K maximum (forget the silly extended change option) and using the correct spec oil for the PD.
10K is too much. 5K is best
Yeah and use a 40 weight oil no matter what.
0w40 for the cold season and 10w40 for summer would be ideal.
Love the fast pace. Tear down in 5.
love this channel. i bet your yard qualifies as a superfund site!
Great video
Thanks
One of the best engines ever made. Still a legend till this day. I own 3 myself. 15 years for my ve tdi enegine with 250k on it. Never had an issue.
Nice!
until its paired with the dsg transmission lol.
Very cool
I own a 2.0L BDK engine code (n/a diesel, 75 bhp) golf with 750k km (of which I did 50k km)
It's weak, it smokes, and I love it
5 speed manual, this thing is absolutely a tank and doing about 900 km / full tank until light comes on (and even then I drove 100km to test, and i didn't run out of fuel) you can't kill these engines unless you don't do oil changes and cam wears to ground.
Got to love the simplicity of a diesel engine!!! Whose toothbrush is that!!!?🤣 Good stuffs as always!!!!😎👍

Thanks
Masha'Allah
love your videos.
Glad you appreciate it
What a ride 🍻🍻🍻 do you have any videos of exhaust after treatment system of the diesel engine...?
Love that you started doing diesels as well! Keep up!
Do a N22 Honda 2.2 diesel engine if you come across one! Those are really more common in Europe though, dont know about the US.
I have never heard of a diesel Honda here in Canada
Didn't know these even existed.
Honda doesn't sell any kind of diesel engine in North America ever
@@kclefthanded427 in europe they do
Never knew Honda made diesels, I'm up I'm Canada
Actually, PD engines had 2-stage injectors, they were able to inject pilot and main fuel doses only. It was one of the reasons these engines had such a poor NVH (aside of 1.508 rod ratio). But at the time of their introduction, they were more reliable than Common Rail. They were pretty nice motors (I've had ASZ type), reliably taking around 170 HP with only soft and north of 200 HP with bigger turbo and proper tuning. Rotating assembly was very stout, the heads and accessories weren't so great though - you've mentioned camshaft, it had too narrow lobes, so failure around 300K kms was common, injectors were asymmetrically bolted to the head what caused injector socket wear. Plus they had troubles with failing AFMs, temp sensors, faulty PCV system (integrated with valve cover, so quite expensive) throwing oil into intake, leaking "tandem pump" (vacuum and fuel pump mounted on the camshaft), which caused oil dilution. No biggies individually, but high mileage engine is usually a source of them all at the same time. And new injectors (unit injectors I should say) cost usually way too much to make the overhaul reasonable.
Doesn't the pilot injection improve NVH? I guess they probably lacked the "post-" injection for DPF regeneration though.
@@simontist it does, but it's still a long way to common rail. But in general NVH in 1.9 PD is pretty agricultural ;)
Thanks for the input, I'm new to diesel VW so I'm learning too!
I think their eventual demise was due to the fact that they couldn't engineer the injection timing to work with the DPF that became necessary. So, for example, post combustion fuel injection wasn't possible as the injector lobe on the cam would be past the point where injection is possible.
@@julianstafford7071 I guess there were more reasons in general, but that was possibly one of them, PD can only make two injection events per cycle. But also common rail got way better in the meantime offering many improvements - competitive (or higher) injection pressures, cheaper injectors, simpler valvetrain (no extra lobes for unit injector rockers), and full control on up to five injection events. So not only good for DPF, but for NVH as well.
Wife's in the hammock right next to him, STILL uses her dress to soak up the oil. Outstanding! 👍
You can also see why those older VW diesels last forever...pretty simple design, all things considered
Yep the boss is in the hammock but too distracted to watch what I'm doing
9:35 Here in EU we tune the sht out of these 1.9 TDI's, they can take alot with a big turbo.
They sure can take it with an iron block like that
Super.
We own a 2008 Skoda Octavia MK 2 ( skoda Laura in India) with 1.9 PD motor . Its been 15 years and 2 lacs KM, still the engine runs like a dream..
Interesting tear down. 👍 I think I'll stick with my ALH engine, it appears to be a lot simpler than the PD engine, and it is still going strong after 416k miles.
The older the better right 🙂
ALHs and other 66kW 1.9s are bulletproof, apart from the earlier 1Z which loved to grenade its flywheel lol. They're seriously understressed, overbuilt and robust in general. It's crazy how reliable these are given their fairly complex design as seen in the video. Not much changes apart from the head and some other ancillaries between the VPs and PDs.
@@jonytube I haven't heard of many issues with the 1Z flywheels. I know the crank timing gear needs to be replaced every 200,000 miles with a new bolt to avoid timing problems.
Is there a mechanical injection pump conversion for the 3 cylinder TDI?
My daily driver has one of these engines, a slightly older design which leaves out the EGR cooler and an pesky DPF. It has been rock solid for the 300.000 miles our family has owned it (the odo reads 330.000), the fact these engines where in so many vehicles here in Europe means they’re easy to keep running even if something big were to fail. The only thing I am slightly worried about is getting a faulty injector, those are costly and will mean, fiscally speaking, it’s totalled. That has yet to happen however and I am glad I can enjoy the engineering of these engines everyday on my way to work.
This one didn't have the dpf either
@@speedkar99 what model year and code was the engine?
Interesting video, thanks. I which you get your hands on Vw Tdi AXD/AXE or BNZ/BPC
Please translate lol
I've been waiting for this one! 🙌 Did this engine fail? It doesnt seem to be in all that bad condition. And that cam looked new, very common for BRMs and BEWs. I know it would be a little redundant for the channel but it would be so cool to see an ALH for comparison. I wonder the main difference between them would be.
THANK YOU VERY MUCH FOR TAKING THE TIME TO DO THIS! (that goes for all the other videos as well)
Its not super uncommon that camshafts break on these PD engines so it might have been replaced.
@@andremartiniuskalstadtjosa1309 yeah, anyone know the specific cause for the cam wear? Some say it's the factory's recommended oil is too thin, never found a solid answer. I own a VE 1.9
@@RandomlnternetGuy I don't know the cause but they don't wear out, they straight up snap the camshaft, sorta common around 300-400k km. Happend to two of my friends.
@@RandomlnternetGuy I guess maybe vibrarion over time and the extra load from the pd injectors.
You are welcome and in glad you appreciate it!
U da man wheeler
Awesome
Very cool that the piston not just has a "bowl" but also a little cone inside there, presumably to direct the combustion?
Yes, exactly, it gives pretty much toroid shape combustion chamber.
Yes it controls it
Great review as always. Makes me wonder. Those diesel's are super reliable with proper maintenance. Less RPM's more torque, better bang for the buck overall. More heat in diesel fuel, more work being done. US cetane ratings PP, 40 on average. Too low as is the overall combustion temperatures from such fuel. You know what that does to the Cat converters. Shame you need to buy fuel additive and DEF. Thanks again Sk99!
You are welcome. And yes they can be reliable engines. Same can't be said for the rest of the car it's attached to..
@@speedkar99 🤣💩👍
cool story bro
Nice teardown! If you possibly could source an ALH code motor (1.9 tdi 90 hp), I would really love it. Those engines are bulletproof.
Is the same engine.
How different are they though?
@@speedkar99 the injections system differ the alh is mechanical
They era very similar yet different
@@speedkar99 bore and stroke, internal components.
@@speedkar99 The engine you tore down looks to be a PD tdi. The PD stands for the type of injection system (Pumpe-Düse in german). As seen in the video, the injectors are located in the head and interact with the cam but are driven electronically. The ALH is the same displacement but the injection system differs. The injectors are purely mechanical (no piezo or solenoids) and there is a high pressure diesel fuel pump located on the engine. The engine si also direct injection one, but the injectors are not in the head, rather they reach the combustion chamber from the side of the head (really easy to get to them). Here in Europe they are still around and although the cars they are in can be up to 20+ yrs old, the engines still refuse to die. Mine had over 600k kms and was still going strong. It is also possible to mod the heck out of them and they hold up. The average consumption can go as low as 3 liters per 100 km, although normal person would get somewhere over 4.5 - 5 l/100kms which is still lower than for PD engines. Many people just scrap the cars because they are rusted through, but the engines usually still run ok. If you sourced one (could be high mileage too) it would be interesting to see the internals and all the bearings tho.
Great video but failed to include the turbo and how it works with these tdi engines. That’s what I was hoping to see
Great video, does a catch cane help to prevent intake clogging?
To an extent. Remember this engine also has EGR
I've never been convinced by them - most of what you see is condensation in the liquid collected. Focus on cleaning of injectors / intake valves and DPF. I'm really unconvinced by how much cleaner the intakes are with a catch can but I'm not an expert.
@@DeepakKumar-lv4te im convinced VW needs to be avoided haha
Is there any major difference between this 1.9 BRM engine and the 1.9 BLS engine?
Is the timming belt wet or dry ?
Thank's in advance
BimmerN53
The cam bucket and direct acting camshaft directly above the inline valves has been used by VW since the 70s. Those engines would easily last 350,000 miles. Its the lack of ZDDP in todays oil which has caused the wear issues.
If you can get your hands on a Volvo D5, pleaaaaaase do it :=) epic diesel engine.
Hello sir I am from India
Can you please explain sum different types of truk engine and and their technology..... Just educational purpose....
Sure
can you do teardown on skyactiv g engine
I'm looking for one.
Do you have any thoughts on the 2022 Tucson Hybrid with the 1.6L Turbo engine? I am considering buying that car but I'm very worried about long term reliability because of the turbo and Hyundai's quality control so I'm debating whether I should just go with a Camry :(
Camry is safer if reliability is your main concern...
Time will tell if these relatively new Hyundai hybrid technology will be reliable...
Ask around to see if mechs will rebuild the Hyundai engines - Scotty was saying none of his contacts would touch them for rebuild but I can't remember if he was talking Kia or Hyundai . So that tells a story, easy to find out.
Don't rule out Mitsubishi or Suzuki (not their old mini jeeps), you have to hope the japs maintain their quality.
avoid hyunDIE or KIA
this is a BLS engine like in my golf 5. my drove allready 292 000 and still running strong, 4motion with 6 speed manual gearbox.
I've had a VW Passat 1.9TDI 130bhp SE 4motion 2003 & SEAT Toledo 1.9TDI 110bhp SE 2002. I also had a Bora 1.9TDI 150bhp courtesy car.
what you're pointing out is actually the fuel return line, the feed line is upper
Of the three lines, one goes to vacuum, one to coolant manifold (I don't know why) and one for fuel
@@speedkar99if you're talking about the lines in front of the engine, there's no vacuum, one is the coolant return, one is the fuel supply and the other is fuel return
Correction: When they say that diesels have uncontrolled combustion they don't talk about the ratio of the air fuel mixture. They talk about how the combustion starts. In diesel engines the combustion does not start uniformly like it does in a gas engine where the combustion starts at the spark plug and the flame front travels equally in all directions slowly burning all the fuel. What happens is that combustion starts at many different places inside the cylinder and happens immediately. Since the temperature rises all over inside the cylinder, there is no specific spot that a flame front can start and expand beautifully like it happens in gassers. Diesel just ignites all over the place instantly
Yes that's what I meant. The propagation of the explosion is rather uncontrolled, not it's mixture.
Its funny, VW stull uses the same sandwich oil cooler they have since the mid 80s. But now it just has a cap holding it on instead of the spin-on filter it was designed for.
I had seen a lot of theese PD engines. some of them was 500k or more. so you could say they are quite reliable. And about that cam washing or bucket grinding problem at 5:50 I have never seen any of theese problems on this engines, even high mileage ones. the only problem is injector bore in the head gets eaten by the injector itself, only because the injectro is held in the head by only one M8 bolt. and that cam rocker is constantly pushing on it. they fixet it on later models by adding another bolt.
Good to know about that injector.
You are right these are high mileage engines especially with a manual transmission
is it a problem if it does 500K ?
@@DeepakKumar-lv4te it really depends on maintenance. i'm talking by Km of course. not miles

That timing belt tensioner is on every VW water cooled inline engine for 50+ years.
They're not paying a lot for them at this point and they don't fail.
True...but why make it so complex
@@speedkar99 The bearing is probably 3x the load rating of others and it's not dependent on a spring. That bearing is the only real moving part.
The tensioner on that engine will outlive us all...and several timing belts...and the entire rest of every car they put them in.
Oh, and it's not complex. Just a bearing, stud and round piece of metal with 3 holes. It is different though.
@@kylegoldston except they always get changed with the belt!!
@@DeepakKumar-lv4te When I used to do them sometimes I wouldn't, not all kits came with correct German tensioners.

Would you like to explain how a BMW N13 engine works?
Good video. Diesel engines do not have evaporation canisters. Diesel doesn't really evaporate. also, diesels don't develop vacuum turbo or no turbo
Good to know. They still need vacuum to control the variable turbo, brake booster amongst other things.
@@speedkar99 some of them still need vacuum. For that they use a pump. They might need it for power brakes. But newer ones don't use vacuum to control the geometry of the turbo anymore.
Weird that an oil level sensor is considered a "premium" luxury feature. Toyota did the same thing with the 1MZ
You’d think that a premium or luxury engine wouldn’t use or leak that much oil between checking it.
It's Volkswagen - what do you expect? ;) They'd still charge you extra for power windows if that was possible. Lousy company with lousy cars.
1MZ had an oil level sensor on the Lexus models but not the Toyota right?

We tune that engine easy to 300 pk and more .
The best tdi engine is still the 1.9 8v turbo.

Hmm do diesels come with variable valve timing?
Not this one...
oh jeez, I do hope not.
13:30 how do you mean there is no throttle body on those engines ?
My diesel has a throttle body.
It depends on the engine. But diesel don’t need throttle to function. I’ve seen both with and without throttle.
What was the reason the enginge has died? I see decent condition of all parts ...
The DSG transmission attached to this engine was going...that's why I parted the car
@@speedkar99 they are not usually hard to fix is that not true? As they are really manual gearboxes plus a control panel.

Well it is now...
Make video with 1.9 JTD from Fiat/Alfa Romeo
Fiat motor would be cool
One of the best engines ever made. Can take a lot of abuse and still go more than 500,000 km
They engines do, but the rest of the car has a mind of it's own
@@speedkar99 how many hundreds of thousands do you want it to last??
@@speedkar99 I don't know. I've seen these engines in old Polos and Golfs just going and going. Old VWs were so well built and engineered.

Sure.........
10:08 Crank Position Sensor in rear main seal 😂😂
Yep
Runs off the flywheel
Had nothing but problems with our 2006 Jetta with this engine. Any advantage with the excellent economy was offset with the numerous problems. Never ran right, think it was a turbo issue. Eventually stopped running altogether, towed to local mechanic and he had it for a few days and couldn't start it. Eventually sold it for $500 as a non runner, guy picked up with a trailer, the same night he sent me a short video with it running, but it did that sometimes and then die again, but good luck to him. These days I stick with Toyota!
Seems like an electronic issue ?
@@speedkar99 maybe, I think a good mechanic could have diagnosed what was wrong.
Like.
Thanks
Only you my dear could tear down a diesel engine next to a hammock 👍
Yes why not !
Just missing the cocktails (and private yacht in the distance of course).
I keep asking this question on this channel. Why does my 1.6 TDCi shake when i shut it off? And no, the motor mounts are all okay.
Is it because the throttle body isn't closing to make it shut off faster?
@@speedkar99 I was thinking the same but wasn't sure. Friend told me it acts more like anty shudder valve than Trottle body. I guess he was right. I'm going to check on it. Thank you for the reply!!
@@CarloLeonKolega Did you sort it out? some diesels have throttle bodies just to help shut off the air when turning off the engine. but they don't rely on just that to cut the engine.
I prefer the 1z ALH and the PD over the bew
Isn't this a BRM? 2006 MK5
You have the vacuum pump because you don't have any throttle valve that closes and creates a vacuum. Doesn't have anything to do with turbo or no turbo.
Yeah, the SDI (non-turbo diesel) also has a vacuum pump. Turbo gas engines do also have vacuum pumps though, I think
@@simontist
Nope, that is not normal. Petrol engines have a throttle valve creating sufficient vacuum whether it is turbo or not.
My 3SGTE doesn't have a vacuum pump for instance.
Yep. That’s why cars have a vacuum reservoir because even NA you aren’t going to create much vacuum at full throttle.
@@calvinnickel9995
Yup, my diesels also have a vacuum canister, at least my old HJ60 and HJ61. I guess it is for high load demand or rapid breaking that the pump isn't sufficient enough to create enough vacuum fast enough.
Turbo waste gate or fins are controlled by vaccum operated actuator ...
That person just chillin on the hammock tho 🤣

I think in most cases if the engine/part is made in Germany, it will be long lasting. Trouble starts when manufacturing moves overseas. The Europeans are somehow not as good as the Japanese when getting things manufactured overseas.
I droved a SEAT TD (VW 1.9TD engine) years ago in Germany, a 1.9TD Renault in the UK and had no trouble at all. I bought a Renault 1.9 Petrol, a Volvo 850 2.5 Petrol both assembled in Asia and had endless problems. Japanese cars on the other hand are pretty much trouble free whether made in Thailand or in Japan.
europe for innovation , japanese for production build quality. It's a stereotype yes but it seems to hold true. the more recent premium german cars are a catastrophe but they still sell well. We'll see how long for. Apparently VW have totally messed up the software on their latest electric cars (from china, they bought a big chinese s/w company, the idiots).

What is the difference between VW TDI and mercedies CDI ??
CDI stands for Commonrail diesel injection.
Commonrail means that it has one pump creating high pressure and sending it to a very strong container (the rail). From there a line goes to each fuelinjector.
Hence the name, commonrail.
@@tantaroba1337 thank you for the reply . This thing i know already ? But VW TDI also a common rail system . But what are the difference between 2 ??
Newer TDIs are common rail as well. It’s just a marketing name. vW likes Turbo Diesel Injected.
@@kavindugilshan nowadays they are all commonrail injected.
Basically it is the same, probably both built by Bosch, since both are german.
I'm a mechanic myself, and worked on Skoda (VW sub-brand), and many VW, Audi, Seat aswell.
What he shows in the video is a Pumpe-Düse injection. VW is the only brand known to me, using this system in cars. I think cummins uses it in their trucks.
Wanna know more about pumpe-düse?
@@tantaroba1337 yes of course thank you .
The head is flat because the chamber is (that hole) in the piston.
Yep
My Diesel backhoe has a throttle body.
Backhoe? Please explain.
Also that throttle is to stop the engine.
@@tantaroba1337 On modern diesels there is a throttle body to better control de EGR rate and DPF regen, although by design diesel engines do not need a throttle body.
It helps to stop the engine. Especially if it runs away
Very informative but man you speak fast
Slow me down
I never knew diesels didnt have a throttle body. So are the "wot" all the time?
Yes. Some do have a throttle body to help stop the engine

it's rather weird common rail diesel engine, my father have Toyota diesel car with common rail system that the high pressure pump outside the engine on it side connected using a belt
Interesting. What Toyota is that? Toyota diesels aren't common here in passenger cars.
@@speedkar99 it's Toyota kijang Innova a MPV car, one thing I know it's only sell in Asian Region, like Indonesia, Malaysia and Japan. it's great engine, plenty of torque, reliable, and relatively easy to maintain. but the diesel variant is discontinued in next gen Innova so the only diesel Toyota left in my country is Toyota Fortuner (it's basically land cruiser mini variant), Hiace (a Minibus), and Hilux
that's the normal configuration for a commonrail engine. The injectors are simpler by not having to generate the high pressure themselves as the PD injectors must do (no high pressure pump in the PD engine but the injectors have a hard life as does the head).
I've got a DCT with mine.
If I have anything to say about it that car will be running for a hundred years.
Let me fanboy a little…

The Mighty 1.9 TDI: How it works
I have this engine in my Skoda Octavia 08. The turbo leaks oil so they are not that good, my car has over 32 thousand kilometers, at 22 thousand I had to replace the camshaft, costs exactly the value of the car if you don't do it yourself. I regret today that I bought a diesel car, and regret even more that it had to be a VW engine.
Sad
This is my lost toothbrush O_o
