Hi folks,

335i E90. Wondering if anybody has heard this type of sound when shutting the car off. It just started today. I had RB Turbos put on the car about 2 weeks ago and recently installed a new battery about a week ago (it was registered a few days ago). Also, maybe unrelated, but starting today the car had a couple of rough cranks upon startup where it seemed the car fought a little bit to start.

Any wisdom is much appreciated.

Thanks!

The little "Pssshhh" ? It's just air blowing past a partly-open valve; nothing to worry about.

Thanks for the reply. I saw on another thread with a very similar video. Turns out their actuator rod/wastegate interface was the source. They lubed the interface and the noise was gone. After reading that, I looked more closely at my video and sure enough you can see the actuator rod move right as the squeak occurs. I'll give it a shot.

Thanks for your reply!
