Ok i have had a problem with my EGR and i have replaced or checked everthing that has to deal with the EGR system exept for the controler on account of it is so expensive. well usually the light turns on after i have been driving for long enough that the car has come up to come up to temp and i am cruizing along and it wont go out till i shut the car off. well today it decided to turn on as normal after the car got up to temp and that really didnt bother me because it always does. but when i let off the gas and costed such as going down a hill the light would go out and then when i would get back on the gas it would come back on. so i checked the codes as i do every time i drive the car for long enough that the light comes on and it was the same as always, only the EGR code 32. just wondering what having the light turn on and off rather than what it normaly does means?
