Could be the diverter valve (DV) as was mentioned above, but also could be a clogged fuel filter - if you hit the gas, you're demanding more fuel and if the filter is partially clogged, it may not allow enough through to the engine to respond to your demands.

02 Audi a4 losing power


You have blown a turbo charge pipe somewhere, check all hoses...Once this happens the car will begin to run very rich, as evidenced by the black smoke. Do not continue to drive like this, as the raw unburned fuel in the exhaust will clog the catalysts and that can be very expensive.

No acceleration,audi 1.8t,runs like no boost


It's possible that the diverter valve (DV) has failed. The OEM valve has a plastic diaphragm inside and it can crack. If this happens, the car will leak boost air and will lose power as a result. Go to www.audiworld.com, click on Resources, then Tech, and then go to the engine article about replacing/upgrading the diverter valve - it'll show you where it is and how to do it.
