Vag-com Codes? I Have 6 Engine Codes, What Do They Mean?

I got some codes from my vag-com, its just the shareware version. anyway, the first is 18077-valve for pump-jet: cylinder #4 N243 electrical malfunction P1669-000-- ? what does that mean?

the other is 17903 switch over valve for E.G.R. COOLER GROUND (N345) P1495
any ideas?



Thanks peeps!

sounds like a bad connection on injector # 4. Get a Bentley, find the correct wiring scheme and test for continuity between the ECU harness pins and the approriate connectors. I belive you have a PD car, so disconnect the big round connector on the cylinder head, and check on the pins there. If all the wiring checks OK, you might have an ECU problems, BUT that should be your last resort.

thanks Dimitri. iwill try that

you can probably check the status of the injector valves in VAGCOM if the shareware allows you..
