Trouble Ticket Help Requests for DTC P0674
Help Request Posted
2002 Volkswagen Jetta TDI 1.9L MIL Lamp on VIN: 3VWSP69M52
P0674: Unknown code. ... mode with the genisys and tech1 both show a code P0674. I have searched Alldata for this code but it dose not exist. If you clear the code it will come back on after one test drive. The vehicle drives fine the only known problem is the light is on.
