Hahaha, thank you
Complimenti bellissimo video, persona molto competente.
Grazie
So just the rocker srm had to come off. Ahh good stuff. I can do that miself.
Hi, great vid. On notice for bmn injector (exchange) it says 12 nm, so why 3nm ? It's better or ?
Thank you,
the injectors bolts are stretch bolts so it needs to be tightened in 2 steps, first tighten the bolts to 3nm and then further 270 degrees, in that way the bolts stretches properly.
Small advice, each time you removing the injectors do not use the old bolts because they could snap, use always new bolts.
Quick question, when adjusting the injectors, it states on the Audi manual that the roller side of the rocker arm should be at the highest point.
In this video it says the opposite (18:58) Could you please clarify? Thank you.
Depends of the engine code and type

Very very helpful thank you so much . Music was awesome too. Just had trouble reading the bit about adjusting the injectors. Could you plz reply to this via a comment plz
You have to set the rockarm to the lowest point for the injector that you are adjusting, after that you screw the injector screw all the way till the injector spring is fully compressed, after that you unscrew the injector screw minus 180°.
Do the same procedure on all 4 injectors.
hello friend thanks for your explanations and videos, one question, do you change the injector screws when you remove them? is it recommended when you remove them to change them new ones, if they are not changed they can break if they are mounted again?
Nice music 🎶
Great video!
Thank you
@@audilover6591 I came across your video, as I have a problem with a BMN engined car and on putting it back together it's not running very well at all. I hooked up VAG COM to it and did some logging, but don't really know how to interpret the data (injection deviation, injection duration and injection start). Is this something you're up to speed on?
@@adwarrior The BMN engine had a big issue with Siemens-VDO injectors, Audi made a recall and change most of them in guarantee.
You’re problem can be in faulty injectors or even faulty (broken) injectors harness, I heard people had problem with it.
The problem I had was that my car had big problem to start after I left it overnight.
@@audilover6591 This is an 07 Quattro with 150K on the clock. The belt tensioner pulled the stud and the belt jumped. Fortunately, as it has straight valves it only broke one of the rockers. After effecting a repair and putting it back together I noticed when adjusting the injector lash as per your video and several other sources that the injector adjustment screws are not in the position they were before I stripped it down, which makes me think, due to age and mileage a previous technician had to do quite a lot of adjustment to get it to run right, so it's probably time for new injectors. I've checked the wiring harness and it's fine. One thing I do notice is that the injector timing is wandering all over the place (anything from 4 degrees BTDC to 5 degress ATDC with no ryhme or reason as to why). It's very puzzling.
@@adwarrior I think you’re injector screws are not the same because from the factory the injectors initially was adjusted -270° and after the revision the new adjustment was -180° because the cars was running even smoother because of higher injector pressure.
So this is why in some workshop manuals you have 2 options 270° and 180°, maybe someone that was fixing your car adjusted to 270°.
Great video . Do have 1 question I'm just wanting to change my seals ,so for this do I need to bother with the compression once I install them back as theoretically nothing has changed position apart from new seals
No need to bother with compression.
Just be sure tu but then back in place nicely, they need to do a small “klick” when they come in place.
This is great! I just bought an ultrasonic cleaner for my pistons in my BHW swap. Didn't think to throw the injectors in there! Might I ask how long you left them in to clean and how much heat you used?
60°C for 15min
@@audilover6591 Awesome, thanks 👍
@@audilover6591 Great Video, but Elsawin states the following:
The actual cleaning process commences when the temperature reaches at least 70 °C and must last for at least 90 minutes.
After 90 minutes, switch off cleaning process by pressing ► button -D-.
Remove unit injectors from mounting plate. Allow unit injectors to dry in ambient air for max. 1 hour. (Never immerse the complete unit injector in the cleaning solution.)
@ good point. Thank you for the advice.
I never submerged the whole injector, but thank you that you point this out.
Thanks for info
What product do you use to clean it ?
Hello, good video will be very useful to me, I only have one question, what did you use to get the injectors out of place? Why have I tried and they are very tight, thank you
I used a metal cable tie, before you pull them turn them around a little bit.
When you pullin out wiggle a little bit.
Hi did you reuse the bolts that holds the injectors in place? I have why smoke coming from the valve cover and rough idle Im suspecting one of the seals are bad so Im replacing all seals but I was told to replace the bolts because they stretch
Yes, that are “stretch” bolts so they need to be replaced each time you remove them. If you reuse them they have tendency to snap.
Does this sonic cleaner always work? What does it do inside the nozzles? What happens when sonic breaks up deposit on inside.. is it possible for it to clog injector exit holes?
Hi, my dad have a blb 2.0tdi when it's hot it takes 7/8 seconds to start, i thought it could be the injector out of regulation, do you have some suggestions? Thanks
Hi great vid. Need some advice however, I have a MK5 GOLF GT Sport 170 BMN. When i accelerate hard past 60-70mph. It feels like I'm feathering the accelerator as if I'm giving gas letting go repeats it's self. Revs don't move so it's not a slipping clutch. Boost pipe under driver side radiator to turbo was leaking so I've replaced that. And I then replaced the clutch and dual mass flywheel too. But issue still remains. It does give abit of black smoke on acceleration not excessive. And abit of white smoke on idle. Bare in mind it's remapped EGR delete and straight piped. Any ideas?
Hi Aliiswell
It’s really hard to tell what could be without being there and test the car.
My opinion is that could be some electronic issue like for example (map or maf sensor, injector harness or even the acceleration pedal).
With the VCDS you can check all off them and see the readings.
Try to remove the map sensor that is situated after the intercooler, sometimes it gets really dirty so doesn’t giving you a good reading

hi. i love your video. very informative. i just done injetors seals.
but can you explain me more about this lowest point? because i done it twice and now.i get.confused because after those.tries engine still.runs rough and with quite a lot of white smoke.
1st time i set lowest point as soon rockarm pressed injector all the away down.
on 2nd try i tied injector srew when rock arm just starred to realease injector( as soon arm.go up then i turned crankshaft bit backwards and then tied up.)
so what is correct why to.do it?
thanks.for help.

Hi, wondering if you can help, I have a gt tdi 170 really rough start when cold and it has an intermittent rough idle like its misfiring and chucks out white smoke that smells like diesel. Drive it then its fine? Could this be injector seals?
Most likely are the seals
Nice video, I have Audi A3 2.0 TDI 170 a lot of white smoke when cold and smell like fuel, when warm or hot less whit smoke but still smoking white not blue. Do you think is the injectors seals?
Could be.
Does the car suffer hard start after 1-2days of non starting it?
@@audilover6591 yes
@@Max-io3he then the cause is probably seals
@@audilover6591 thanks for reply
How do you set piston 2-3-4 to the top. Setting number 1 I think is fine with normal crankshaft locking tool?
All the pistons are set in the same way. In the description of the video you can find the workshop manuals.
You don’t need a locking tool
Hello friend. Maybe you can help me
I had misfire on cyl 1 on 2.0tdi blb. After I replaced all 4 injectors (used in good condition) the car no longer starts. Unless you try for a whole minute it will start and die. What could it be? I don't get any fault codes
Hi Carlos,
it can be few things:
~ one or more used injector can be faulty
~ faulty or damaged injector wiring loom
What you can do is test witch injector or cylinder bank is faulty.
You should disconnect the injector 1 wiring and try to start the car, if starts (engine will work roughly) that means that the faulty injector is the one you unplugged because the engine can start with 3 other cylinders.
You have to do the test with all 4 injectors in the same way
What you can do is

Hi great video, especially its the same engine as mine
i have two bad injectors and Siemens injectors for pd170 are not amazing, my mapper thinks best and cheaper option is to switch to bkd pd140
Couple questions if thats ok!
How was you moving the engine for adjusting injectors as I couldn’t see in the video
What was you doing at the end with the pliers by the rocker arm, plugs?
I need to change the wiring look plugs for bkd, what would you do, Un pin then re pin into new plugs?
Where did you get your new bolts and seals from?
Hi, thank you.
- I was turning the engine on the crankshaft pulley, (need to remove right tyre and remove the plastic around the wheel.
- I use the pliers to connect the glow plugs harness.
- I think you need a new harness for the injectors because I don’t know if there’s the same connector because the BMN injectors are using piezo coils, I didn’t do that so I don’t know the answer on your question.
- You can buy seals and bolts trough the Audi dealer. I bought mine from Autodoc, elring is the manufacturer.
thanks for the reply
-sounds easy enough
-iknow i need the bkd plugs but not 100% sure if the harness will fit,
-is that a good brand for long use or just a cheaper option?
What was the process after tightening the injectors and plugging in the plugs, did you have to turn the crank to a certain point or anything?
Was was it turn crank to allow fuel or something then put gasket and rocker on and start it?
@@itzjordxnhd9850 Elring is really good brand for seals.
After I adjusted the injectors to the spec, I turned the crankshaft for 2 full circles to be sure that everything is ok, the I changed the valve cover gasket and tighten the cover.
Before the start of the engine I turn the key for few times so the fuel pump can deliver fuel, then I start the engine.
The engine will straggle to star because lack of fuel, you can expect a bit of white smoke after first start.
@@audilover6591 what brand bolts did you buy?
Did you do anything about ‘injector lash’ or is that when you’re tightening the bolts?
@@itzjordxnhd9850 Febi bolts
Hello, I've changed my injectors today with another set of refurbished ones and followed all the steps. Unfortunately I have starting problems now. Tried it for longer than 10 minutes before I quit, because I was afraid of killing my starter. What could be the problem? Air in fuel system? should I try longer ? Thx in advance!!
EDIT: Just read the conversation between you and "Louis Cleaver"....
I'm sure the injectors were pushed in completely, before I inserted/tightened the screws.
Hello.
Could be air in the fuel system.
Also my car had a hard start for the first time after I cleaned injectors. What I did is that I put the ignition ON for 10 times (wait for 5sec between the cycles) without starting the car, I did that just so the fuel pump in the tank can pump the fuel up to the tandem pump to prime it.
@@audilover6591 thank you for responding that quick. I’ll give it another try tomorrow 😊
Here I am again. Started fuel pump activation via VCDS several times. Engine is Running!!! Only problem is, that it’s smoking heavy and runs restless now. Any Ideas?
@@Skjaxon did you adjust the injectors like on the video?
Do you have Piezo-VDO Injectors
@@audilover6591 It’s a Golf 5 (2008), BMN 170hp engine. I adjusted them even with a dial gauge and turned the screw back to 180°.I Followed the VW instructions including all the new screws with the right torques.
After it ran for 15-20 minutes in idle, I turned off the ignition. From now on it didn’t even ran in idle anymore. When I made it running, it only ran with a little throttle. As soon as I took my feet of the Pedal it ran out. No failures in engine memory are saved.
This solved hard starting? What ultrasonic cleaning fluid is the best to use? Is this a 2L machine?
I’ll do this procedure tomorrow. I’ll use regular gasoline as cleaning fluid put in a glass jar. The jar is then submerged in the water bath (tap water). Use no heat. Faster than anything. There are a couple of videos here on CZcams comparing gasoline with a couple of other cleaning solutions. Gasoline clear winner.
Olá o porquê de fazer essa limpeza aos injectores?
Please write in English
Great Video! How to udnerstand when you wrenched to 3nm? Maybe i didnt understand what mean 3nm. First time trying something like that. :D
Use torque wrench
NM is newtonmeters. You might pe used with poundfeet. It;s the measure unit for Torque.
If you follow closely what happens in this video, sometimes he decides that the tightening required after the torque wrench is maybe too much, and he does a little less, maybe for fear of damaging the bolts...
Great 👍 I don't have a cleaning device. Can you recommend an alternative to cleaning?
Thank you.
If the seals are still ok try run the engine only on Liqui Moly Diesel Purge, helped a lot on one another car I did.
I will release one video next week on how to do that.
The best is clean it with ultrasonic but this way can help also.
@@audilover6591 I have no problems running quietly and no signs of dirty injectors. but the maximum speed is not reached. I use Hydra diesel Power blast. Maybe it helps

Hi Dany
Yes I used an ultrasonic cleaner with a heated solution. I order my one on Amazon.

Hello! These nm values is good for 2.0 pdtdi BKD (skoda octavia) ?
Yes, it’s all the same. I did one BKD engine couple of weeks ago.
Great vid mate
My mate (mechanic) recons my injector seals are shot, as I’m burning a lot of oil, he recons fuel is thinning out the oil causing it to get past the rings/seals...does this sound feasible to you?
200k miles with a 4 month old new turbo
Cheers
Do you have any other problem then just burned oil?
Did you do the compression test?
@@audilover6591 no compression test
Just burning oil.
When I done an oil change it, the old oil was VERY thin and stank of diesel.
@@toddy9141 also can be that the upper seals are not good and you have a leak of diesel in the cylinder head, this can be the case.
Try to open the cylinder head cover and investigate.
@@audilover6591 thanks mate 😃👍🏻
@@toddy9141 no worries. Good luck
Hi quick question do you need a pull down tool for the injector to torque it too 270⁰ degrees
I didn’t need any additional tools
Perfect thanks
What are the ribbed ones left over at the end for ?
What were the symptoms? Is the engine quieter after lash adjustment?
The symptoms was really rough start, shaking when idling and a lot of black smoke on high revs (this was because the injectors were dirty).
After a seals change and injector cleaning the car starts beautifully and really smoothly.
Is that a kit you can buy? My octavia vrs is having exact same problems. I need someone who can do this for me
@@curtisbaldwin5649 Hi Curtis, yes there are kits you can buy, depends if you want an OEM or no OEM product like elring.
Hi, have you used also new socket head bolts (N 105 811 01) how it is recommended?
No, I changed only new injector bolts (03G103385A), they must be changed each time because they tend to snap if you reuse them.
@@audilover6591 Yep, I know that. I've been curious about head bolts. Both of these items should be replaced according to Elsa/ErWin workshop specification. Cheers from Poland :)

What symptoms did you have so you decided to change the seals on the nozzles? Can this be checked via VCDS?
I have a BMR Passat 125kw PD, end of 2007. The car pulls great, but the first morning ignition is longer (cranks over 6-7x) and if I leave it for 2 days then it is even longer cranking. When I turn it on for the first time, each next starting is fast (1-2x cranking), until 7-8 hours have passed then longer cranking again.
Someone tells me it could be the cylinder head, although mine has a C mark. It loses coolant, although my mechanic tells it leaking at the water pump. I'll do a belt replacement, a water pump so we can see if it stops leaking. There is no white smoke while driving, but when I start the car, if cranking longer then 7-8x then there is some white smoke but it disappears immediately. The engine runs quietly, in harmony. No smoke while driving. I changed the battery, repaired the starter, changed the seals and gasket on the tandem pump. Could there be a problem with seals on the nozzles?
Sorry for long story, but i really need your help.
Thnx in advance! :)
I had the same issues like you described, long crank and white smoke at the start.
My car had also a bad injector so sometimes my car was shaking at idle
@@audilover6591 Thanks for your reply.
I have two more questions.\
Which torsion value is best for these types of engines - 125KW pd siemens, 2007. year? Someone says 0.0 and someone tells me -2.5. Who should I trust? :)
And when I set the intake camshaft to the desired torsion value, is it necessary to synchronize the exhaust camshaft with the intake? Or do I adjust the exhaust independently?
@@radulepg I didn’t adjust the chamshaft, I just adjusted the injector after I reinstalled them. All the information you need you can find in this workshop manual on the page (36,37,38). drive.google.com/file/d/1hrboC0VOFb2LMrjOJI3znleTybrVgiKZ/view

How much resistance should you time the injector for?

Give it a bit off resistance, the injector have to be fully compressed, from that point you have to turn back for 180 degrees.
Let me know if you have more question.
@@audilover6591 thank you,
So wind it until it stops,(no force other than the spring resistance) and then back off 180?
