taking n55 335xi in to dealer - car seems slow
I don't know where to begin, but my '12 335xi coupe just seems to not be building the boost it should. My car is bone stock with 10k on the clock, and I don't have the time/expertise to run a boost pressure test. I want to take the car into the dealer and have them check it out, but my issues are just so vague. I'm not sure if they will actually test things out or turn me away because nothing is actually 'wrong' with the car.
It definitely feels noticeably slower than even 5k miles ago.
Here are my observations:
-When the motor is cold, the car is ungodly slow.
-The BOV hiss sound seems to kick in at odd times even under full throttle
-At over 5k rpms under load the power band seems to die
Do you think it's worth a trip to the dealer?
