03 Jetta MIL light code P0103 ?
2003 Jetta 1.8T. I have a recurring MIL light with code P0103 (O2 sensor
circuit malfunction circuit 1 sensor 1). Does this mean I need an oxygen sensor or could there be another problem. Light comes back on shortly after resetting. Thanks

You might have a warranty on certain emission components including 02 sensor
and catalytic converter. At least in the USA it might be 7 years or so AFAIK. "Earle" > wrote in message ... > 2003 Jetta 1.8T.

O2 sensor yes, but could be wiring harness issues. 4yr/50,000mile warranty
but maybe longer if in California. "Earle" > wrote in message ... > 2003 Jetta 1.8T. I have a recurring MIL light with code P0103 (O2 sensor > circuit malfunction circuit 1 sensor 1).

Possible meltdown including wiring being overheated.
