BMW 335i n55 Long Cranking and Engine Malfunction
Hello Everyone,
I'm having a couple weird issues with my 2011 bmw 335i N55. The first issue is a long cranking before start when the car is off overnight, almost as if there's no fuel. Sometimes it'll do it for a couple days and then randomly it'll be fine and start instantly in the morning. Also, sometimes when it does (cold) start, the rpms will jump to the 1000-1200rpm range like usual but then it cuts the rpms right away to the normal 700-800rpms, and idle like that with no change. The second issue is engine malfunction. When the car is started, I'll get an engine malfunction, reduced power notification but the power is still there. I've gotten this type of message before and the car barely has any power when it pops up, but in this situation, everything is fine and the car drives normally. The engine malfunction, reduced power message will sometimes go away on it's own after a little bit of driving, but it's random. Im thinking of a few culprits, specifically the HPFP or MAP sensor If anyone else has expericened this or has some input it would be greatly appreciated! |
