Last week the 7-speed DSG box of our March 2009 Volkswagen Touran Diesel packed up, having done 53,000 miles. As you can see from the mileage we do mostly distance driving and little in city traffic, moreover we drive without any towing or exceptional load carrying. Fortunately we had extended the warranty when it lapsed last March, so we will not bear the cost of any repairs, but the incident made me wonder whether the DSG boxes are now out of their teething troubles. Are they sufficiently reliable to run the car to 150,000-200,000 miles, as we originally intended to, or would we better exchange it at, say, 100,000?
