Had my car for just over three years, three years three months to be exact, just out of the warranty. I had it since new and it has done 17,000 miles. My MMT has gone wrong and the dealer is quoting £700 plus labour. Can this be right for a car this new and low mileage?

I would be grateful if anyone else could tell me of their experiences regarding MMT

Although your car has low mileage it's immaterial, if it's just out of warranty it's bad luck. The dealer is with in his rights.
