Hi we brought our colour storm a few months ago now It's a 1.6fsi but it's had a hesitation problem on it since we brought it. Runs lovely when you get the revs up over 3k and is quick and smooth but below that it's sluggish and not as nice to drive. We took it to a VAG specialist for a full service and they told us they could find no faults on it at all but that the engine was a BAD code engine which was a combination of old and new technology could anyone tell me if these engines are as the engine code suggests BAD engines and would it be worth sourcing a newer 1.6fsi engine from a golf or audi a3 to put correct the problems?
