Hello,

So my 2007 335D pumps out thick white (Blue so I have been told) smoke. Fine when it's idle but soon as you give it some revs it pumps it out with a smell of fuel/oil. Still drives fine and have power but unable to do so as it leaves a trail of fog and smell.

The AA guy said could be the injectors and I should do a leak off test, any ideas where I could get one of these done and are they expensive?

Couple of garages I have spoken to straight away said I need new turbo but I don't fancy spending that kind of cash on repair and rather get a new motor.

Any help will be much appreciated,

Thanks

Just to calm you a bit i think its like 1% that you need new turbos..

Any codes?

Thanks,

No codes as of yet, will try and get that done.

if it was your turbo it would be black smoke. u would literally leave a black trail. leak off test shouldnt be expensive if you are handy with things like that you can grab a leak off tester on ebay for about £40 loads of videos on youtube instructing how to do it.

do a smooth running test that would indicate an injector issue from the results. inpa ista delphi they all do it

[Mus22]

also another thing if you have access to any of the above diagnostics make sure your injectors are programmed per cylinder. let me know if your local i can plug ista for you to test

Can you explain what does that mean and how do i check that in ista?

I did smooth running test with positive results but im not sure what "programmed per cylinder" means.

edit: sry dont want to hijack the thread im just curious

i need to get it up infront of me and ill do a video for you basically each injector has a 7 character number onnit on the diesels which basically represent values you need to tell the car in cylinder 1 the injector's code is ........ and so on. ill get some instructions on here this helps the car also run smoother

Here is a video I found on youtube showing how to do it apart from this being for petrol.

Same procedure just different codes , link below

The diesel injector codes will be on the top of the injector not on the stem like petrol injectors. I have attached a picture.

Thanks for that, will check it out.

Are those values visible if i remove the engine cover or do the injectors need to be pulled? Do you know?

[Mus22]

all visible by removing g engine cover
