Year of Manufacture *: 2005
Engine Size and Code *: 1.9 TDI ,BKC
Got a strange one which is starting to bug me, its a 1.9TDI (BKC) (8P) 2005.
Customer has had this starting problem which was getting worse and now wants it fixed before selling it.
He knows that if the engine w/l didn't come on with ignition it will not start, so he cycles the key until it comes on, then it starts and runs all day.
Garage have replaced the ignition switch with no change to the problem, Scanning engine with VCDS brings up 19781=Voltage supply terminal 15 (implausible) intermittent (P3325). I have replaced the 2 x relays in the engine bay box, ATP phoned me and rebuilt the ecu after there testing showed up the same problem on there test bed, when i refitted the new ecu back on, it started first time on the button, I left it running on idle to warm up but after ten mins it cut-out, it re-strated and never did it again?. Customer has had it back 2 weeks with no problems, it broke down in the week and has been returned to the garage, had a quick look, guess what..... same problem and fault code again? .
ATP will retest the ecu for me to see if anything has gone wrong, but I'm thinking this is being caused by something else on the car. Any advice/help please.
