Asked by Sep 25, 2012 at 12:56 AM about the 2001 Audi A6 2.8 quattro Sedan AWD

Question type: Maintenance & Repair

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

When your water pump failed and you lost coolant, did the car overheat and you continued to drive the car? The alternator seeming to fail was probably coolant on the serpentine belt making the belt slip, and causing the alternator not to spin properly. If it did overheat you probbaly damaged the engine hence the low compression. The fix is a engine rebuild. I'm surprised your dealer didn;t go into specifics on what to do next to fix.
