Wooshing noise and Engine Malfunction after repairs
Hi all,
I finished a number of service items and buttoned up my '08 535 last night. Ran it in the driveway and everything seemed fine, until this morning...
Under acceleration, I hear a rattling or wooshing noise. Under heavy acceleration, car chimed "Engine Malfunction, Reduced Power". This cleared when I restarted.
Here is what I did to the car:
-Replaced tensioner, pulleys, and serpentine belt
-Replaced oil filter housing and cooler gaskets
-Replaced engine valve cover gasket
-Walnut shell blasted intake ports
-Replaced throttle body gasket and intake manifold gaskets (x6)
I'm guessing that I didn't get something properly re-installed. Maybe where the front air charge duct connects to the front turbo? Maybe I damaged the rear charge duct while pulling the intake manifold?
Any thoughts before I start taking everything back apart???
Thanks.
