How can they be?  They don't know how shitty your fuel is.

Just general poor performance.  The car will fail the fuel flow test,
which involves disconnecting the fuel feed line under the bonnet,
sticking the end in a bottle, and measuring how much comes through
with the pump running.  For the ur-quattro, it's 900ml in 30 seconds.

Any less - change the filter.  If that doesn't fix it, change the pump.
