    The 3.2s and 3.0t are notorious for timing chain/guides/tensioner issues. Not sure to what degree on the 3.2, but it's VERY common (almost every owner has had some sort of run-in with it from what I've seen) on the 3.0T. Make sure you start the car in the cold with the door open and listen for a grinding on rattling noise. For around a second, If it makes the noise, it's okay. If the noise persists, it needs to be fixed. (though if it does it at all, better be safe over sorry and get it done)

    Chain job can go for around $2000+

    Water pump and thermostat on the 3.0T are common failures as well, and off of the top of my head it'll run over $1000+ to fix. You do both when one breaks because theyre close together, and hard to reach.

    The 3.2 A6s have some issues with the steering column, not sure how common (I've seen a few posts about it) which requires a new column, I think it'll take you over $1000.

    Both have issues with carbon buildup around 100k+ miles, but my car is lower mileage so I don't know off the top of my head. I think a carbon clean can run 800+

    I'd say, If possible, shoot for 80k-90k miles. If I was buying, I wouldn't go over 120k. Make sure the car has a good service record, and see if anything mentioned above has been replaced (especially some of the 3.0t items, they're re-designed parts)



    There's probably other issues I'm not aware of, and take the fix prices with a grain of salt. I've seen costs in the ballpark of what I listed, could be more or could cost less depending. Personally I'd recommend a 3.0t If you can find them, much more fun+power, and you can tune them. They're pretty rare though, even moreso than the 3.2 Avant

    Having had both a 3.2 and currently a 3.0t, with none on the mentioned issues above, Iíd always say go with the 3.0t. The increased power and response from the engine is incredible, also, in my experience itís always better to get a newer vehicle.

    Although, for the record, if I could do it all again, Iíd have gotten into a Q5. Just food for thought.

    Take a look at these, documents some of the more common problems. I agree with the guy above me- 3.0t is better overall. The cars have also had oil consumption issues on a less-common basis, having to do with the PCV system (requires supercharger to come out I believe). Feel free to look through this C6 forum if you've got some time (and the links below) to see some of the problems people have had.

    So I just bought an 09 3.0T Avant. I live in Maryland and had to go nationwide to find one I wanted.
    Prestige with cold weather package.

    19 inch sport package is killer but even harder to find and easily remedied.

    I would only get a prestige - it doesnít add much to the price in the used market and the audio and backup camera among the other things are really worth it.

    Make sure you get a PPI done no matter where the car is located. Mine is in San Diego so I called purems and mike did a ppi for 106 bucks. This uncovered some very minor problems that would not have noticed.

    No matter what get a ppi done if you are buying private party.

    As people said, itís a more tunable engine as it shares with the s4. That said an off the shelf exhaust pretty much doesnít exist and intakes are limited. I plan on going custom exhaust and will probably do the roc euro intake.

    Good luck in your search. IMHO nothing beats an Audi Avant. There is a nice prestige with 19 inch sport in Sherman oaks CA or about 13.5 with 106k on auto trader. I considered it but found a red one with less miles.

    WTB C6 A6 Avant 3.2 vs 3.0?

    I disagree with the timing chain issues being more prevalent in the 3.0t. There are some instances of failure, but overall much less than the 4.2 and 3.2 motors.

    The big downside of the 3.0t is the layer of extra complexity with the supercharger and possible failure points added there. My coworker with a 3.0t s4 has lots of expensive repair bills. I just got a 3.2 A6 because the thing is much simpler and things are easier to get to if they do break. If you need/want the power, get the 3.0t, otherwise 3.2 is probably sufficient, but that is an older motor at this point so you will be stuck with higher mileage results, which might push you back towards a lower mileage 3.0t anyway.

    Iíve heard that. Might be too loud. I plan to make a custom cover for it to attach to the heat shield so itís completely enclosed which would deaden it a bit and keep the air cooler.

    I have a 2009 Avant with the 3.0t. It has 125k miles and eats oil like a champ, but I love it. I'm pretty sure it needs the PCV system addressed and I plan to take the job on in my driveway once the weather clears up and I build up the courage to do it. For the last 30k miles I've just kept a 5 liter jug of Liqui Moly 5w40 in the back and top her up when she asks for it. I usually have to add oil every 1000-1400 miles which isn't ideal.

    The only other issues I've had to deal with are front and rear drivers side wheel bearings that I had a shop do for me.

    I changed out the plugs and valve cover gaskets a few months ago (SUPER EASY JOB DO NOT PAY SOMEONE TO DO IT FOR YOU! ) While I was in there I used a scope to check out the condition of the cylinders and there was quite a bit of carbon baked on the piston heads so I'm sure the intake valves are a mess. Should probably clean that up during the PVC service too.

    In 40k miles of ownership she's never thrown a check engine light, but I do have a small EVAP leak that throws a code that I'll eventually get around to solving (maybe)

    Either way, I adore this thing. I had to shop far and wide to find one of these things and I hope to put at least 300k miles on her.
