Engine Performance problem
1998 Audi A6 6 cyl Two Wheel Drive Automatic 100000 miles
hello, i am looking at an AUDI A6 2.5 V6 TDI SE ESTATE 98, but the car has a problem. When you are on the motorway, it appears to be fine, however when on normal roads and you accelerate, it seems to hold back and slow down. There is also a crack in the plastic cover on the engine block, this might be totally irrelevant and not relevant, but just thought i would mention it! Any thoughts???
