Hi When my S3 was having a new clutch recently, the guy at the garage reckoned my car felt slightly underpowered. They offered to put it on the dyno and take it from there but I declined. I haven't done anything about this as until then I hadn't noticed anything wrong. Of course, I've now been over-critical and having tested the car for a couple of weeks I wonder if they have a point. It's still fast. Turbo can be heard and no warning lights. But I don't think it pushes me back in the seat like it did. Are there any common faults that could account for a slight loss of power? I am considering taking the car for investigation but wanted opinions here first. Thanks.
