AndyDaBoss · 11-17-2011, 10:06 PM

Hey all, so tonight while i did a lil high speed run 60-130, when i let go of my gas the half lit check engine light came on . My power has been greatly reduced as it feels like a camry i once owned . it seems to me like an hpfp failure but how do i know forsure ? I turned off and started the car up again and it cranks up fast and smooth so idk if it really is an hpfp failure? any idea ? i have a 2008 335i btw

i turned it on again and the warning light is gone but my rpm's are not stable it slowly drops all the way to 600 ... what would cause this to happen?

I had the same prob yesterday and the light didn't come back on today. I brought it to the dealer to have it checked out and it turned out to be a dirty VANOS solenoid. All they did was clean it, under warranty of course
