Hi everyone,
I was driving this afternoon, and the engine light came on. Just a solid light with no flashing at all. When I did the error retrieval, it came up with the P1684 (which I did have a new battery put in, but it was over 50 starts ago), and the P0401 code (which is an EGR issue).
Would it be safe to assume that I need a new EGR Sensor with this code, or am I going to have to dig into the system further to track it down? The car drives fine, as far as I can tell.
One other annoyance that I've had since purchasing the car is a knocking sound in the engine. I've had oil changes and other tune-ups, and no one has mentioned it at all. To my knowledge, it doesn't affect the performance of the car at all, but is just an annoyance.
Thanks for any information, and have a great day
Patrick.
