I have a VW Transporter T5 2007 with 2.5 TDi BNZ engine. I have the following fault code (among many):
p1503 Generator Terminal DF (Load signal) Signal Improbable.
This fault code gets repeated logged after about 5 minutes of driving at the same time as the ASR light comes on.
On SEATS (Also VAG group), apparently this is often a broken wire in the alternator loom, but I cannot find any information for VW T5s for this fault.
Please can any one advise what might cause this.
