Dear friends,
I check the A2 1.4 petrol (AUA engine) with my vagcom today and found this fault:

17621 Fuel Inyector for cyl 1 (N30) short to plus P1213-35-40 Intermittent.

I have a new coil pack ready to change (032905106E) and all spark plugs and cables too. I am going to change all this weekend. Do you think this change is the solution? Or do you think there are another cause?

Many thanks for all help and excuse my english.

Cheers
 
Check the wiring for injector on Cylinder 1 to start with. If it is an intermittent fault, wiggling the wiring around the injector may recreate the fault or make is disappear.

Let us know how you get on :)

Thank you for your help. I've checked the cable and cleaned the connector with a special cleaner spray.
I haven't had time to check again, I'll do it this afternoon.
Anyway, I am going to change the coilpack, spark plugs and four cables this weekend.

Thank you.

Best regards
 
Done!
Finally I changed the coil pack, four cables and spark plugs yesterday night. I cleaned all the injection connectors and test the A2 for about 20 km. and all is OK again. Now the car runs smoother.
A few month ago, also changed the EGR valve and both oxygen sensors.

Thanks for your help.

Best regards.
 
I really do hope it has solved your issues, however, my honest opinion is that the fault may return as what you've done may not be to fix the fault but, just to put it off temporarily. This may be because for example, the injector wiring may be broken and fiddling with it may have temporarily reconnected it till next time.


Anyway best to take the car for a motorway run for about 20 miles to burn off any unburned fuel in the cat, and to save the cat from damage. An exhaust emissions test would show the levels (of hydrocarbons) present. Usually this is taken care of by the ECU, by cutting of the fuel to that (misfiring) cylinder, however not knowing the type of misfire, I would give it little run :)
