Hello follow e90ers, I'm in need of your assistance.
I got a 2009 335i which was boosting fine with vrsf 7.5 intercooler, vrsf CP w/ tail BOV, fuel it stage 2, mhd stage1+ e50 ots, xhp stage 3. I installed the vrsf downpipes 4 weeks back but never took a log after, the car was noticeable quicker up top. 2 week ago I noticed a blueish smoke coming out of the exhaust, its noticable 30 seconds after I start the car with a warm engine, then goes away after driving a quarter of a mile. Searched around the forums and figured it was a blown turbo seals, but this past week I haven't seen any smoke out of my exhaust. Did a data log today and saw that I'm underboosting and my wgdc goes up quite a bit. The car has 80k miles new vacuum lines and boost solenoids 5k miles ago, coolant level is full and oil has not went down. Do I have blown turbos or what?

Try replacing your turbo seals
