Very expensive SQ5 TDI engine rebuild. Still need more money?

- Welcome to the second video of the SQ5 TDI
. In the previous video we had this car delivered to us with a knocking sound from the engine. After a very short diagnostic the worse scenario was confirmed. Bottom end damage ... Owner managed to get a second hand bottom end that was delivered to us to build the engine on that. So we get to work ... If you think that was it you are wrong... more money is needed after the engine starts.

Props for giving the customer the option for using a mix of old parts based on budget. Makes things 10x more difficult for you. Not releasing the vehicle even though the work is done is why your shop gets mad respect. Keep us posted on this money pit!
I would be in heaven I a workshop like this, I'm a BMW enthusiast though. Enjoy your content
I got so excited when I got notification of new upload.
Loving the content and knowledge sharing.😊
Really enjoying your videos. I’m a newbie to your channel but it is a joy to watch thank you 😊
Another fascinating video.... what a job you have done... respect top bloke
Have the same car and the same engine. Respect to you for giving the customer chance to save money. )
Great video guys keep up the work enjoying the content 👍
You’re probably on first name terms with the parts person at TPS. Great job.
always love your videos VAG buddy keep up the good work :)
Best content on CZcams imho 👍🏻
The more technology in the engine isn’t always a good thing ,nice rebuild guys
Technology is good...until it fails
Theres so much shit on this engine, just why cant you just build a normal engine
@@kirilakmadjov8307 You can make a engine that run more or less good performance as this car with LESS technology = less problem = less cost and so on.. sooo, more technology is not good.
Amazing job and you have reminded me why I will never buy a complex VW/Audi product.
WOW what a build, great content great edit
Love the new dramatic music , say hi to shop dog.
Like mentioned by me before, I own a A6 V6T..perfect car but, dpf filter, egr ventil, oil cooler had to be done..now it needs a new sensor for exhaust gas..and I am waiting for the turbos to fuck up soon since they do weird metallic sounds. Gonna sell it whilst I can. Bought it for 38k€ and repair’s so far are over 8,5k€..no service included(had to change the oil twice after parts came in. Perfect motor but once it starts to fail it’s a mess. Own it for a 1,75y made about 60000 on it bought it with 88000km on the clock. So anxious about this video.

Great job, great video, keep going.
Thanks for another great video...👍👍
Genius’s at work on Audi’s! 👍👍👍
I'm not surprised that this build is a challenge. It's great to watch your channel, it makes so relieved that I've finished with Audi ownership.
I just wang to add my prais ... and respect to you snd the team 👏 doing this sort of job is a big act of charity and you are really going out of your way to help a fellow human being in trouble..
Ues this sort of thing was done all the time in the 60s 70s 80s and you could probably get away with it up to the early 2000s .. but now !!!! Just lookmat all those pipes the vacuum system the wires the turbos!!!!!!
What a totall nightmare and in the end i predict the injectors are what killing the old engine in the first place ... over fueling like mad diluting the oil burning the piston and wrecking the barings
Lovely cars audis but there getting 2 complex to maintain now
Compare this to an rs6 B5 .... that is like childs toy tomwork on in comparison...
Anyway your a good man and a great Friend 👍
And a marvelous engineer
The lesson i take from this is prevention is cheaper than a rebuild 😢.
The lesson you take DONT BYE AUDI after 1.8T ! PERIOD
What a job 👍🏼
Beautiful Doberman she’s beautiful 😍
Great work bro the bottom end will be fine
I don’t know how you manage to remember how to refit everything, great work 👏🏻👏🏻👏🏻
Yeah I think that too! I do some big jobs, but nothing compared to what those guys do. Dread to think what the repair bill will be! I'd dread to turn the key after that rebuild
@@ritchieschofield1185 😂 that stomach churning feeling starting it for the first time is horrible
Большое спасибо. Мечтаю приехать к вам на обслуживание :) Thank you very much. I dream to come to you for service :)
I love your level of sarcasm 😅 .
I have just bought an SQ5. Now, after watching that I'm prepared to change the oil every 6 k and listen out for trouble before it becomes expensive. Great video, thanks
Isnt this one Like crt engine, which needs remap in order to get rid of that low-pressure mode haha
It's a good practice to have any way for older "performance" cars. If you want it to last, preventative maintenance is key, some people look at you funny when you do things before they are "needed" but it's better to be on top of it before the problems occur.
I have the same mentality with my V8 RS4, I might only do 6.5k miles a year in it, but it's still getting 2 oil changes a year.
Hi guys just need some advice from you as you seem to know the CRT engine, I have a 2016 Audi allroad with a CRTD engine , what are your thoughts on it for longevity?? any help would be appreciated
@@SalimKhan-gk1fh Hi Man, on slovakia they made a remap so the Oil pump stays 24/7 in High-flow mode, would Be worth a try
@@Callagwhan is it a good engine in your experience
Love your videos i watch every one all way thru love it but i have a Audi A5 3.2l V6 with 120k miles i havent had any issues at all i change oil thats it i have it in my garage cause all audi control arms go bad but i would love to know have yall worked on the 3.2l V6 or has it had a bad rep cause everyone i talk to says they still drive their car on forums people have well over 200k so keep it up guys cant wait to see more and learn more thank you guys for real THANK YOU
Awesome video, really professional job, there is only one thing i can't understand: why did you keept the old sets of Connecting rod bearing? Few hundred extra buks on this kind of bill should be not a big deal for the owner...
Anyway, this is a fantastic engine rebuilt! Congrats From Rome, Italy!! 🔝🥂🍾💪✌️
Great vid
so what about the injector packs? the injectors need to be replaced ( all of them ), then this should resolve the issue. Awesome work as always as this has been moulded from concrete and the innards were cleaned properly.
Good videos
Have you noticed, the problem is with injector 1 and 4..(front - oposite each other - one in plus and the other in minus). I think the injectors can be alright, its just the ECU compensating some kind of "unbalance-timing" from the engine. it can be minor.... but if no errors on VCDS... ECU is defenitly compensating. hope it helps.
If the injectors are good next step will be checking compression. Check also the ecu software if is stock, can be bad remap
Great work sir. Did you verify correct head gasket thickness after the skimming was done per the measurement test? I know that can cause some strange issues if the wrong gasket is used. I’m sure the injectors were adapted with vcds just trying to think out of the box have been in that same situation with these 3 liters, good luck
That engine have technology of space rocket engines...No wonder car prices went crazy in last 3 decades with all those complex solutions added...
hi, great first 2 videos, any update on this car?
great work once again you can only work with the budget the customer allows you . After watching a lot of your vids it's enough to put you off buying an Audi performance petrol or diesel but having said that all cars have there own problems . 👍👍
It's a VAG specialist garage. So I would expect their content to be solely VAG no?😂
@@utensil999 yes i do know that your missing the point all i meant it ts not just VAG made cars that have issues it's others too .
Have a look around next time you’re in a busy motorway service station. There’s a good chance you’ll see a recovery truck. Take note of what’s being recovered. I’ll save you the trouble… it’ll be a Land Rover Discovery.
Judging the relative overall reliability of a brand by what’s on the ramps of a workshop that specialises in repairing that brand is ridiculous.
Cars that are expensive to maintain and repair eventually become cheap enough that people who can’t afford the running costs buy them.
The tyres on a performance car normally give you an idea of the mindset of the owner. Mismatched cheap tyres tell you the owner has expectations way beyond reality.
Yes and I totally agree there with what you just said .
Ahoj kolego, regarding the injectors still keep overfuelling - the ECU is probably using the old values it learned while compensating injected quantities for the old engine, what I would do is reset the injectors in ECU memory and do a new adaptation for all of them using original codes printed from factory if according to the testing shop they are alright but would like to see how far within tolerance they are and if tolerance have moved too close to the limit then refurb and adaptation with new codes ... :) ... but I guess it has been sorted by now anyway
Amazing video!! You have got serious skills! Question, I’ve been reading the 3.0T of the b8/8.5 having scored cylinder sleeves usually on cylinder 6… any idea what’s causing this or any preventative maintenance?
Nice work, Did the owner put a crap map on it. which caused the over fuling in the first place
I'm at 1:30, The main thing to worry about is crank sensor location, I have been caught out in the VAG brand with this before.
Yes , that was checked all same
Your fantastic work cannot be praised enough. Haven't seen any repairs on 2.0 engines yet,but surely there should be a number of breakdowns on these (TSI) too?
bravissimo....👋👋👋
Your dog is like "Are we gonna play or what?!" 😅
remember kids. If you can't buy it twice, you can't afford it!
So can you afford to buy you're house twice ? Such a dumb thing to say. Not a pack of sweets is it.
I think it’s a sensible comment when talking performance motors 👍
If you can’t pay cash it isn’t yours
At least half the price 😂😂
It's an Sq5 not a ferrari.
When I first started racing I would complain about younger guys taking stupid dives up the inside and causing damage. And older guy said to me if you can’t afford to brake it you can’t afford to own it. Has been with me ever since. Makes life a lot less stressful if you stick to it, and yes, I would count my house in that too.
Perhaps i might be wrong, but isn't the compression ratio different between the 2 engine codes? The BiTDI engines have a compression 16.0 and the single turbo engines CDUC/CDUD compression 16.8. Perhaps it won't matter.. just something I noticed.
Great video. Informative and interesting. Just curious. Do the owners of these cars not keep up with servicing? Always thought preventive maintenance was the holy grail of keeping any machine performing as it should. Or are these machines just a bit fickle and poorly made?🤔 Hope not, as I've recently bought a 2015 SQ5 tdi. It had its issues, but all fixed, and thankfully the repairs were not to the extent that's needed done to some of the vehicles you guys work on. Keep the videos coming please.
super .
Hola podrías decirme si la parte baja de un motor CVU es compatible con una CDU muchas gracias un saludo
Dude check the maf sensor 😮we had a problem.someone installed backwards 😊
how often should the tension clamps be changed ?
German reliability at its finest
Yeah audi sucks
Germans are too intelligent with their tech,if you baby german cars with preventative maintainance they can be good cars.i know i own a polo playa 6n2 1.4i but it also makes me furious constant gremlins
have you seen the color of the oil? the baby was in bad hands.
I'm sticking to my Alfa Romeo😂
Not the German engineering is at fault here. Given the looks of the old block and rods, etc, this owner probably changed the oil 2 times since he owned the car. Even if it's a diesel, you need to count in the operating ours not only mileage, and based on that, change the oil every 8 to 10 k kilometers ( i use European stuff, don't know Imperial). Changing the oil on ANY car higher than 10k km will bring the engine to its death far sooner than later. Forget what the dealer says... Probably what the dealer says is valid only on German Autobahn where diesels like the most, but not even there. When i hear maintenance schedules to change oil at 15k km or 30 k kms my back hair becomes wolverine.
Can you guys give us torque specs for all bolts. And why are you blowing oil and water channels with compressed air after you have sealed the bottom of engine, where it that dirt go
Thats some job that
The repair bill? I dread to think. .you must have so much patience!
It’s my car the repair is around £12k 😅
I wouldn’t touch a big litre diesel again back to Petrol after this
“if you can’t tell, i can’t help you” 🤣🤣🤣 save this man he’s had enough 🤣🤣
After watching that i'm glad i've got a trusty old Euro3 Volvo D5 engine that's easy to work on and gives me 53 MPG on a run! 😂
Same here 2004 e-class 3.2l i-6 cdi. Abit more expensive on the road tax in my country but so easy to work on and 45mpg on a run with autobox and stage1 tune 260/600nm
Is that a dipstick on the bitdi? Interested in the part number please!
How do you mill the heads without setting variable valve timing codes? I’ve seen milled heads create out of expected parameter timing code errors.
Did you make the next episode for repairing this car? Can't find it on channel :(
Great work guys, amazingly complicated.Reminder to myself, never buy one of these!.
excessive rich mixtures leave loads of unburnt fuel in the cylinders/chambers ...which washes the lubrication of the bores, and causes elevated wear ...also, fuel goes down past the rings into the oil sump, which dilutes the oil lubrication, causing engine bearings to be improperly lubricated. So, worn bores and destroyed bearings.
great video upload. I hope you can sort out the problem :)
its a diesel mate
Did you check the piston rings on the second hand engine? Also would a compression test help diagnose the fault with the fueling? Love your videos guys.
Well if you have metal in the engine there’s no point doing compression test . Piston were out and cleaned because there was loads of dirt . Everything was checked because I don’t want to build something based on scrap 😀
@@VAGTechnic I did mean a compression test on the newly built engine not the scrap one. Sorry didn't realise that you took the pistons out as well, think I missed that bit. 😎👍
@@VAGTechnicif the new engine has a slight different crank shaft stroke diesel fuel pump will not not produce the same ecu desired fuel pressure and your injector fuel delivery will be off....somthing to consider
Genuinely interested. Why didn't you change the crank bearings? Makes sence while its open and in components form? Cheers
Hi , very tight budget , you’ll understand in the next video
I’ve just done my turbos on my s4 🤦♂️what a job 😂
See nuh you guys
Lol u keeping me awake at night
So did you fix the car in the end?
I think the problem with the injectors is the engine compression, the DEHA is 15.5:1 and the replacement short engine has different pistons giving 16.8:1 compression.
Problem Was sorted
@@VAGTechnic hi, what was the issue I’m facing the exact same issue
Great insight, gents... German engineering=Great when it works=Nightmare when it doesn't ££££££££millions of pounds😂😂😂😂
Old timing chains and guides 😢. I almost would cough up and donate the money to a go fund me just to see the old ones thrown away and all new fitted. 😂😂😂
This speaks to the level of ownership and maintenance this vehicle has had. No wonder it has failed at 44k.
There is no follow up, what was the problem?
Another great video. Another Audi money pit 😂
@3m lol that crank was needing polished
Needed new rings as well , new bearings as well question only is who will pay for it 🧐😀
Got some Slovakians working eh? At least it’s not like in Slovakia where everyone wants a nice car but complains at the cost. Then again, same here in America. Nazdravje!!!
km or mls ?
Good job boys! Bad job Audi engineers
Is it common practice there to rebuild an engine for VAG? Not sure if its VW Audi specific but domestic vehicles here if something like that happens they just replace the entire engine and refuse to rebuild them as it is too costly in labour to do so
Straight new unit … but bare engine is 18k plus injectors + HPFP + timing ++++ = milion £ + vat 👌🏻🤣
@@VAGTechnicwow! £20k plus for an suv engine? The lease rates on a new SQ5 were excellent. Either the formula used to calculate future value is flawed or the people who buy them used need better advice!
I wonder how much a warranty costs for a used SQ5.
Load up the Parts Cannon!!!!
Next time just conrod bearing and clean the internals
Just to make sure, you did program the IQA codes for the injectors correct?
No point unless they're new out of the packet or at least nearly new.
What is the running total so far?
My guess is lots, or maybe lots and lots and a very poor owner after all those parts.
another t-shirt " if you can't tell, I cant help you" 🤣
….after customer spending 1 million pounds at TPS…
Had to Find cheaper option This time
Bad fuel pressure sensor? They get really bad before the ecu recognises it. And bad remaps, which just ramp up the fuel pressure, kill them really quickly.
If this poor running condition was the original root cause, I suspect the cats/dpfs have seen better days.
Failing that, it’s time to start switching around injectors.
Terrifying, all that time effort and money and still not fixed 😳😳
The dog wants to play football.
Where is next video?
Didnt upload it 😪 but happy ending
I’d have thought the car is an economic write off? I have an A4 3.0 TDi which is a great car to drive and is awesome in the snow; but I now drive Mazdas because of the scary costs of complex VAG cars. If the Audi breaks seriously it will be a write off.
good grief yet again its the outside suppliers causing grief ,,, how much are new injectors cost wise over checking the old ones ?
Theyre about £280 each
@@BenJamminJones1 not that bad actually.
It is when you have to buy 6 of them! 😢
@@BenJamminJones1 range rover are 480 each , and you need eight of them ,,,, see , your winning already lol
@@BenJamminJones1 dont price a high pressure pump then either .
now rember another parts (not factory) live short than original.
you Must change injector 256 not injector 1 .4 because 256 are in + and when you change those 1 and 4 come to 0 . Blla blla .
😀 nope
So needlessly complex for such mediocre output, the concept of a 'performance diesel' always seemed like an oxymoron to me.
I have audi a6 c6 avant with 3.0 Tdi 176kw CDYC diesel engine.... Ill buy next audi also 3.0L engine this time powered by gasoline. Which audi engines are good which ones are bad and I should AVOID them? (sorry for my stupidlly bad english language).
Reliability ended with R5 engines.
Customers buying and bringing parts is the worst.
>They buy the wrong stuff.
>Fake stuff, cause they buy stuff of websites that sell OEM stuff for 50% cheaper.
>The straight up buy the worst brand aftermarket part that barely fits.
All for trying to save like 100 on a 3000 bill.
Seems to me these engines are nothing but a money pit👎
Like any other engine repair
new injectors needed --- i bet the spray pattern is poor
Audi, is a great car, but an overengineered money pit, at the same time.
Overengineered designed to fail after warranty just to keep their workshop's in business but never mind the poor sucker who bought this peice of crap.
A Kia or Hyundai nowadays is a much superior car.
German cars are no longer of the quality they once were.
You must be Polish!! Why not throw in some performance rod bearings ?
Taking notes 📝 open an Audi shop to get rich drive a Toyota to stay rich 🤑
All the experts in here acting like poor maintenance causing an engine to fail is strictly a VAG problem need to go watch some I Do Cars.
yeah? I own VW and Audi and not once had any problem :D
Yikes. Thats all I can say mates. 😅
