Hi,
I have a 2001 1.4 Petrol (Engine Code AUA) with the following Vag-Com errors
I have cleaned the throttle body and cleaned up the earth points (as suggested)
4 Faults Found:
17582 - Fuel Trim; Bank 1
P1174 - 35-00 - Injection Timing Deviation (Balance Fault)
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-00 -
16685 - Cylinder 1
P0301 - 35-00 - Misfire Detected
16686 - Cylinder 2
P0302 - 35-00 - Misfire Detected
Readiness: 1010 0101
The actual symptoms are that it will run fine for 2 mins or so, only when cold and when it's up to tempature the
EML will flash and it starts to run very roughly.
80% of the time it is only cylinder 2 that is mis-firing, but also cylinder 1 (as per Vag-com diags above),additionally most of the time the error logs does not show the 17582 - Fuel Trim; Bank 1 P1174 - 35-00 - Injection Timing Deviation (Balance Fault) error - just the cylinder 2 mis-fire.
I've replaced the spark plugs, ignition leads, ignition coil, fuel filter, camshaft sensor, oxygen sensor (post cat), knock sensor
Also swapped injector from cylinder 4 and 2 (to eliminate a possible injector issue)
I've checked compression across the 4 cylinders and they are all approx 220psi
I've also noticed that the actual spark on on cylinder 1 and 2 is a bit weaker than cylinder 3 and 4 ( not sure if related ?)
Any thoughts ?
Thanks in advance.
