Hi
New to the forum and wondered if anyone else had the same issue as I am having. Engine management light has came on a few months a go. Took car to the dealership and they said it was an issue with the Adblue sensor. They re-set it and test drove the car 20 miles. The light came on again last week and took it in again. They now claim after looking at it that I have over filled it with Adblue which is not covered by the warranty and want nearly £400 to drain, recalibrate the sensor and fill to 80% to see if it fixes the problem. The car has done 35k miles, in warranty and I only fill the tank when The dash told me to, which is rare and never overfill it.
any advice / help would be appreciated.
