Engine Malfunction: Code: 2AAF

ensoniq · 10-10-2018, 04:35 PM

2006 335xi automatic.

when accelerating rapidly error comes up; "Engine Malfunction: Reduced Engine Power..." and SES light come up.

scanned, shows: code 2AAF "DME: Fuel Pump, plausibility".

I am reading and searching and reading finding different answers:
to replace LPFP, HPFP, LPFP sensor, charge pipe leak e tc..

Any values I can check for or live data parameters when when driving to figure what the problem is ?

(I have Autel maxisys and launch pro3 x431 diagnostic scanners.)

Ok now another code also is showing:
"30FF: turbocharger , boost pressure too low"
