Newbie to this forum,
I have a 2001 VW Jetta TDI with 186,000 miles. The check engine light comes on after driving one mile or more. I checked the ODB II, and received an error code of P0420. I had the motor replaced last year and it had the same error code before and after the swap. I replaced the EGR value and still the same problem. All help will be appreciated.
