I know this is dumb question, i pretty sure i know the answer, but i have problem with fuel on my 08 335i, i bought it at real cheap price because of the fuel problem, so i can fix it.. scanned it with on ISTA+ and its giving me 3 errors.
Parts I already replaced:
Low pressure fuel sensor upgraded to the BOSCH
replace the MAP sensor with OEM BMW had an aftermarket one installed.
pulled the and cleaned the IAT on the charge pipe
New BOSCH sparkplugs, oil change, filter replacment

DME: fuel pump, plausibility- Low Pressure Fuel System Delivery Rate out of Range
DME: intake-manifold pressure sensor-overrun
Manifold Absolute Pressure Sensor 'A' Afterrunning Diagnosis Pressure Implausible
DME: Boost pressure sensor-overrun
Manifold Absolute Pressure Sensor 'A' Afterrunning Diagnosis Pressure Implausible

I'm pretty sure i have to replace the LPFP because the HPFP looks like it had already been replaced. Maybe have to replace the EKP?


thanks in advance.....
