335d Turbo Failure

Our 2011 335D with 65k started to consume oil without any clues to why. Then we started getting whitish smoke at random times (yes, White not blue) while idling or accelerating. It got worse and worse until finally the parking garage at work said don't come back. I'm guessing the PO used low grade oil or never changed it. I had to change a leaking oil supply line when I first got the car at 45k and noticed oil was built up quite a bit at the banjo bolt fitting.
After I pulled the turbos, I found the oil return line was coked up almost completely, which probably forced oil past the small turbo seal though the large turbo and into the DPF. I had to replace both turbos and DPF...And right after I got it back together and celebrated...Active tank sensor failed! At least that was covered by the extended warranty.
I'm surprised I didn't get any codes related to boost pressure. The small turbo wasn't stuck but was difficult to turn with my fingers. The large turbo was covered in oil but still feels really good and was supplying boost.
It was going into reduced power limp modes when the symptoms started so I performed a CBU cleaning which it definitely needed but that didn't help of course. Thought I'd share in case anyone can relate.
Also, are there any recommended oil treatments people have ran through their engines before an oil change to get the gunk out?

Hmm... this seems kind of like what my car is currently doing. It has been consuming oil, and there are traces of white smoke when I decelerate at highway speeds. I am hoping I can catch it before the turbos completely fail, if that's the case. I will swap out the oil feed lines, and see if that helps.

Be sure to look at the return line as well. Here's what it looked like inside.

This sounds very familiar...Last week i took my 2012 335d for its normal oil change, check up and glow plug check - all was done as usual - however when I picked the car up and started out into traffic - the engine all but died. loss of power, Big engine light came on and said Serious Engine failure. Luckily I was only feet from repair place - brought it back. Just spoke to my repair guy he states that the Small Turbo is not working - yet everything seems fine - he cant figure it out. But he is still looking. Any suggestions?

What bmw specific codes did you or your mechanic get? Without those it's stupid to assume the turbo died

Get a new mechanic. Hopefully they put oil in it (correct oil too) if so hopefully they didn't charge for a glow plug check. Invest in a solid scanner, such as foxwell nt510 or schwaben tool (same thing) and pull the BMW specific codes. We could possibly help if you have those. FWIW there was no 2012 335d in North America.

2012 335D in North America

Yes they exist - I have one. Not many available - but you can get them. If your looking, go to car-gurus or cars.com they are there.
I'm sure my mechanic will figure it out - they been in business since the 60's.
I was just wondering if anyone had similar issues - and what the cause was.

It is easy to check the model year and production date. Go to a VIN decoder:

Would love to see last seven digits of vin. I recall 2011 being the last model year although production may have continued into early '12, they were sold as MY'11.

I could be wrong, so curios. Good luck on diagnosis

Not just E90 335d production ended in 2011...ALL E90 production ended in 2011. If you have a 2012 model sedan (regardless of what's under the hood) it ain't an E90.

M57 didnít go into model year 12 for a simple reason. F3X chassis started with sedans in MY12. Our diesels in NA are only in sedans. Bmw would have had to pay to recertify the M57 in that new platform and that would have been economically silly to do for a short build.

I bet you have a MY11. I know I was shopping in September 2011 and they were about to stop making the 335D. My memory recalls around June 2011 was end of the run. Yozh has one of the last I believe.
