I have had my little a2 since new and it has not given me any problems until now. I have been having intermittant problems with the operation of the drivers window - it has been getting stuck up or down - changed the fuses and the operating door switches and it worked for a week, but today again it has stuck in the open position. Quick trip to audi - they say it is either the regulator (£237) or the motor (£311.28) but which one ?? Do not plan to get audi to fix it - can anyway help with instruction on replacing one or both of these parts - your advice will be gratefully received many thanks
