Great to drive, horrible to maintain

2001 Audi A6 2.8 Avant Quattro AWD 4dr Wagon (2.8L 6cyl 5A)


Where to start ? Bought a 2001 A6 avant in 2006 with 106K on the clock. Car was in very good shape.
Within a year started having some issue.
Did timing belt replacement which is normal maintenance (about $500 in Audi parts if you do yourself). Have replaced the ABS module, 2 combi (EGR) valves, valve cover gaskets, etc.
At 149K had to replace 3 steering arms ($700 at shop).
Now transmission is acting up and need to replace at 151K.
Still have problems with secondary air system and was told by tech probably carbon build up in intake manifold after all other attempted repairs. Great car to drive but very expensive if you don't do the repairs yourself.

Best Features

Performance and handling - fun to drive. For a wagon it is impressive. Quattro system excellent in snow and adverse weather. Good visibility and comfortable. Interior of car is very good build quality - no squeaks or rattles, even after 150K. Very surprised at suspension. Was looking a new shock by Audi tech asked why ? Hardly any bounce after recoil. Instruments intuitive. Has the foundation of a very good car but has too many common failures.

Worst Features

Improvements - in listed format. These failures are very common on the A6(C5) 2.8l platform (99-2001). 1.) ABS brake module (rebuild is about $200) 2.) Instrument panel - driver info center. The pixels almost always fade on every car. 3.)Secondary air system carbon build up problem- this is still an issue with the newer Audis. 4.) Prone to oil leaks, partly due to plugging of the crankcase breather system. 5.) Serviceability - ie. you need to remove the bumper & other parts to service timing belt. If you are going to buy Audi in this model year I would suggest buying a VAG-COM reader to diagnose inevitable check engine light codes. This is a difficult car to work on.

A follow up to my previous post. Since transmission was failing I park the car until I could find a good used one as the value of the car did not justify doing a rebuild. After much research and after I found a low mileage used transmission (EKD code) I have found that there seems to be a built in defect in these transmissions. The problem is with the bushing that connect the pump to the torque converter. This will eventually spin off from the pump to the torque converter and after time will ruin the transmission. It even started doing this on the used transmission but did not do damage to the internals. It is not a matter of "if" but when the tramsmission will fail. The 2001 MY A6's came with two codes, EKD and FAS. I do not know of this was the problem in the FAS as well but it effects all EKD transmission made by ZF. Also, the secondary air problem I referred to earlier was not from carbon build up. I removed the intake and found there was little carbon build up for the amount of miles (151K). Only two things that it can be is a bad air pump (vacuum seem fine) or bad celonoid switch.
