Hi all,

My A2 show many warning lights (Christmas tree inside ), I get : EPC, Red light brake blinking, ABS and ESP.

Engine is flanged at 4000rpm, I have cleaned up the throttle body and I have sprayed WD40 on many electrical connectors.

On vagcom I got these errors :


5 Faults Found:
16785 - EGR System: Insufficient Flow

For EGR, I add a blank plate on it. I have also misfired on 2 cylinder.

I think all of these issues is from one cause but I don't know where. Could you help me ?

Thanks.
 
the EGR hasn't been coded out. is this petrol or diesel? Why did you blank the EGR?

You also have a different problem with your climate control unit.

It's also possible there's an error with the yaw sensor (g200) - that's the one directly under the front of the gearbox. If it's off, you'll get those errors (and ESP is off).
