Hello,

So my 07 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.

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

T

Bluish white smoke usually mean it is burning oil. How is your oil consumption?

It has been fine as far as I know and had an oil service couple months back. Can't seem find any one genuine to test it! They all just want to change the tubro!

My Dad's old E46 330d has similar symptons - new turbo cured it.

You have two turbos. Any decent garage should be able to an injector leak off test and also check for turbo failure. I think your car has the M57 which also has a crankcase breather valve which should be changed in the event of turbo failure.

Thanks, beginning to make sense a bit. One of the garage said they need to take off injectors and send them for test. Not sure if that's the process.

Will research into a decent indy garage.

A leak off test is done in situ with a kit such as this:





You can even make your own for very little cost.

You can get the turbos refurbed, it isn't such an expensive job since those turbos are so popular.
You would need to do that anyway to shift the car - it's practically scrap otherwise.

How is your oil consumption ?
Whilst it is running, take out the dipstick and see if any smoke comes out.

Mine did this and was diagnosed as a cracked piston ring.
The turbos are usually pretty good on these.

New or recon turbo a far better option than diesel runaway. That's what finally wrote off my old e46 330d. The fire brigade arrived,I hadn't called them. "We saw the smoke from a couple of miles away mate",laugh just wish I'd filmed it on my phone. To the cars credit it was displaying 320,000m !!
