Hi,

Does anyone know what a P3FF1 error in the ECU is? I keep getting it coming up and disappearing in time to take it in to BMW. Sure enough, within another 200 miles it appears again.

iDrive gives me the Yellow Engine light and 'Increased Emissions' on the screen.

2007 525D

Thanks in advance

Thanks in advanceIt shouldn't disappear - the ECU stores the codes.
