Considering what might be a bad, expensive decision…
I currently have an '09 S6 with 135K mi. that has been my daily driver for 5 years. I have really enjoyed the car: styling, sound, power, uniqueness etc. I have not done any JHM performance mods but those should make the car even more fun. I have, however, spent a ridiculous amount of time and money having it repaired by local mechanic and an Audi dealer. Many of the issues turn out to be small, inexpensive parts that take forever to find. The CEL usually comes on a few times a year for one reason or another. Right now the CEL is on and occasionally low oil light flashes, yet it has plenty of oil. Also the ESP light is on, no idea what that’s about, haven’t had time to run a scan yet.
My current thought is to buy a lower mile version of this car, do the JHM mods and replace other things while they are in there (coil packs, etc) then keep the lower mile car as a second vehicle for many years. In several decades, this V10 will be an interesting model to own with all of the turbo, hybrid and all electric models being produced today.
I don’t work on cars myself so I’m at the mercy of someone else doing the mods and keeping the car running. There is a very good VW/Audi shop 45 min away who has done great work for a friend’s S4. They seem very capable of getting a car into good shape.
What I don’t want is to dump more money into another S6 to occasionally drive the car and still have CEL problems and other issues. Is it even realistic to think that a car like this can be tuned and repaired to keep it running for a long without error cods?
Also, how hard is it going to be to source parts for these in the future?
Other V10 owners have any thoughts?
