I have a little fabia with the 1.2 BZG engine and I've been having a bit of trouble with its running I have a fault P0171 Fuel trim,Bank1 system too lean (short circuit to B+) and its flagging up faults for the fuel pump, lambda sensor, solenoid valve n80 etc but all showing the same fault code and fault (as said above). I have put a new lambda sensor and engine Ecu on it but still have the same fault. Has anybody seen this before or can help? Thanks

Fairly sure an 08 plate Fabia is the mk2, unless it was a very late registered mk1. If it is a mk2: Try over in the mark two section, you will have more success over there I'd expect.
