Conencted a CReader V.
Got a P114C
and P124C (twice)
The reader says these are manuf specific codes, but when I chose 'BMW' couldn't give more info.
I googled and eventually found a P114C:
Post catalytic fuel trim via oxygen sensor too rich (bank 2)
Couldn't find anything for P124c
Looked at the 'freeze frame' data for the P124 error - fuel trims were:
ST Bank1 3.11%
LT Bank1 -3.13%
ST Bank2 0.77%
LT Bank2 -5.77%
So, does this suggest bank 2 post cat sensor is knackered?
Which is bank2? Driver or passenger side?
