Audi preowned less than six months, bought from Audi dealer. My last car. Jaguar, had same problem and they were never able to fix it after many times in the shop. Friend told me the same story with her VW and was finally covered under the "lemon law". Any Advice?

Hi there,

A miss fire I one cylinder should not be that hard to locate the problem, the need to first do a compression test, check injection pulse, spark & ignition CVA readings, checkfor vacuum leaks around this cylinder, most problems will be around these issues, start here.
