"Engine malfunction reduced power" after warming up and accelerating. Please help

Mannyd · 11-02-2019, 02:40 PM

Hey guys been having this issue for several months now. After my 2011 335i warms up i get the "engine malfunction reduced power" message. It comes on every time i accelerate and disappears as soon as i let go of the gas pedal or start cruising. As soon as i press the pedal any further to pick up speed it comes on again. I have a 6 speed mt so i get the light on every shift which gets annoying. Pulled codes with mhd and the only thing i get is a "332e terminal 87_1 no voltage" no idea what it means and there's very little info on it on the forums. Car drives 100% normal even when the message comes on. Im completely stumped on this one. Any help is highly appreciated

ISTA will pull code history. Likely 30FF out there.

What about the 332e-terminal 87_1 no voltage) that i pulled from mhd? Also would a bad boost solenoid explain the fact the light only comes on after the car has warmed up?

When mine went bad it happened after hard acceleration but drove normally

Did u get any bsd code? Also check ur battery

332E is not germane. Any speculation on causes without relevant code history is pointless.
However, you can probably address the 332E by unplugging your IBS.

Most likely some sort of problem with the boost and turbos. Were the turbos ever replaced?
