not sure if this will help you, but ASR light comes on when you turn off traction control. on a stock car, when you unplug the MAF, the ASR light stays on (you can't turn it off). try unplugginh your MAF and see if the car behaves any differently. I could be wrong, but maybe you have a "bugged-out" MAF. Like i said, unplug it and take the car for a spin, see what happens. If problem is gone, i'd try a new MAFPlease help. We have the same issue as the original poster and have been through two cycles with a local shop. Latest vag codes are 16486, 18032, 01166, P0102, P1624
This prompted them to check vacuum with smoke test and found a broken oil dipstick (replaced) and a vacuum line (replaced). On driving home we had the same issue occur with some rough shifting and ASR flash. Very frustrating.
