So my wifes '11 is 35D is in the shop right now for new front brakes. The CEL has been on for the last few weeks. They topped it off today and reset the code, afterwards it came back on (2x). The code they said they are pulling is the AdBlue sensor. They said if it happens again they are going to replace the sensor. I have searched the forums and not seen anything similar. Thoughts?
thanks
