Have been considering an A3 sportback for some time now & have now seen a three year old A3 2.0 TFSI Sport with DSG which I am very tempted by. Any advice please ? Have read that some DSG / S Tronic cars have "launch control" feature to allow better take off - would this be fitted on a 3 yr old car ? Postings also report TFSI engine as being quite noisy - simply the way the engine is & nothing to worry about ? Any comments would be much appreciated. Thanks in anticipation.
