ECU code P29F3 - BMW 3-Series (E90 E92) Forum

KCX_335xi · 11-24-2011, 09:47 AM

Got this ECU code after reading via COBB AP.

Anyone else run into it ? Has to do with fuel pressure sensor.

Already made an appointment with my dealer since I have extended warranty.

What symptoms was the car experiencing? This morning my idle was extremely rough and the car was vibrating like crazy under acceleration. Also from what I understand my Hpfp was already replaced before I bought the car and its now under certified warranty.
