My wife's Outlander's "Service Engine Soon" light came on over the week end. I keep the car maintaned well . I went ahead and took it to the dealer , they had the car in the shop for about 45 min. and said that they reset the EGR valve. I have never heard of resetting an EGR valve , I have replaced them and maybe reset the computer but not reset them. The car has 33,200 miles .

Any feedback on this ?
