Today my manual transmission S4 lost power for no more than a second or two ten times in about 150 miles. The gas pedal was depressed and the speed was as high as 60 and as low as 20. It never happened going downhill, but on level to uphill grades only. The car was at a close to constant speed each time as opposed to under acceleration. No lights ever came on to indicate a problem. The car has 32000 miles and has been maintained by the dealer. Anyone have any ideas I can ask the dealer about when I take it in to be diagnosed? I have owned the car from new. This is the first time anything like this has happened.
