The reason I changed the egr valve was a local mechanic told me the code come up that it was bad.
The key I have is one of the thick ones that has a chip in it; the car will not run without it. The dealership said when I bought the car that it shut the system down without it. I asked which system it deactivated, one time he said the fuel system, then he said ignition system so I am not sure which one it kills but it will not run without the key.
As for the codes, I stopped and got a code reader from a friend and when I checked the codes, they displayed as, 401, 171, and 174.
I watched the theft light and it seams to be flashing five times then pauses then flashes six times.
What dose this mean and what would you do to fix it?
I would really be very greatful for any help you can give me. Thanks haircut
