I have a vw golf cabrio v reg and this last year I have noticed an intermittent fault where the car suddenly loses power. It slows down and the dash lights come on to show stalled. It happens on and off but more when petrol tank down to quarter full. I have had a mechanic use diagnostic and the results were
01243 intake manifold valve short circuit
01249 inj 1 short circuit
01250 inj 2 short circuit
01251 inj 3 short circuit
01252 inj 4 short circuit
00635 o2 sensor heater circuit short circuit with ground intermittent.
since then ive had new cat and lamda sensor and took to jct 600 volkswagen who gave me a print out of faults but could not link my problem to any of them..those results in red were...
servo pipe split
Coil pack earth lead broken
dizzy cap rotor arm
spark plugs and ht leads.
since then I was advised by another mechanic it could be ecu..but when trying to replace this part I was told it does not exist for my make and model..apparantly my car is a mark 3.5?
can anyone shed more light on this please. Im from west yorkshire area thanks...
