my 01 audi a-6 twin turbo haI took it to an audi dealership and they replaced the battery and alternator as well as the lower fuel pump. When I wenompression in one cylinder and low in another. Why?
never before has this car given me problems but over half way thru a 600 mile trip i began going thru coolant. Then the alternator seemed to be failing. Warning lights were going crazy. An Audi dealership replaced the lower water pump battery, coolant tank for $2700.00. When I went to pick it up I was told that I now had one cylinder with no compression and another with low compression. What happened and what is the fix
