Contact a mechanic that specializes in Audi's or European makes... make sure that he is certified..
If the repairs are too costly, you have two choices:
1. Fork up the $$ if your car is not under any type of extended warranty...
2. Be in the market for a new car (hopefully it won't come to this) - unless you really want a newer car...
Audi's have always had the bad rep of breaking down after they have given you their best years (like 4-5 years after their birhtday)... so you might want to consider that for future reference...
I hope it all turns well... good luck!!

Sounds like it could be the idle stabilizer valve - this is a valve that regulates air intake and stabilizes the idle making it less rough! It could also cause hard starting (car seems to start then stalls). After a while the ISV gets dirty and needs to be cleaned out. If you are handy, it is easy to do by yourself. Just follow the air intake from the filter, the ISV is normally near the throttle body. Remove it and spray with throttle body cleaner (not carb cleaner) . You'll probably find it to be filled with black gunk!
Someone else mentioned plugs and plug wires. Plugs are always a good thing to change and it's worthwhile doing anyways if they haven't been done in a while. Wires could also be the cause, but it's hard to say, do you notice more of a problem when it is wet/raining outside?
Oxygen sensors don't even get used when the car is starting so it's unlikely to be that. Coil packs are a known problem (more so on the 1.8T engines), but if you had a bad coil pack you'd really notice it (i.e, car pretty much undriveable).
You might also have a vacuum leak somewhere... any hoses seen unplugged?
If it were my car, I'd start by cleaning the ISV and changing plugs which are the cheapest/easiest things to do, and maintenance that probably should be done anyways.

Sounds to me like a vacuum leak. Have you checked all the vacuum hoses along with the air intake boot? It also could be low fuel pressure but not very likely if the car runs fine other than what you say.

how long has it been since you replaced the spark plugs in it the 2.8 v6 that those vehicles are equipped with are sensitive to the plugs fouling out they need to be replaced every 40k miles. make sure to use plugs from audi do not buy aftermarket plugs they dont last very long. another known issue with those cars with higher mileage is the plug wires arching out to gnd. a good way to check the wires is to take a spray bottle and fill it with salty water and spray all the wires and ignition coil assembly. then brake torque engine slightly a few times and check for external sparking of wires make sure to check down in the cyl head/valve cover area wear the wires connect to the spark plugs spray a little water in that area to. if you see any external sparking on wires replace them with factory wires and if coil archs externally replace it too. hope this info helps you i see these same issues on the passat v6 engine.

You probably have a faulty coil pack the v6 was prone to this there was a recall in Europe for this fault Regards Mick. PS Have just checked Audi owners club USA they are reporting coil problems also .In Europe its the Sagam type coils that are mostly affected Hope this helps Mick

how long since last tune up.check fuel delivery may be low fuel pressure

most likely the throttle position sensor is bad or the oxygen sensor.
