Changing the alternator itself is the easiest of tasks on the A6. It's getting to it that is a problem.Here is how.Disconnect the headlight connections the remove the headlamps.Disconnect the water hoses between engine and radiator.Remove transmission cooler pipes from radiator. (You have to plug these somehow to prevent loss of ATF and dirt contamination)Remove spot light covers from bumper. Look under there and you will see 2 alled bolts fixing the bumper to the chassis. Undo these.Next remove the bumper bolts on the fenders whichn yo can only reach through the headlight holes.Ease out the grille and disconnect any wiring that could be strained especially the one on the radiator lower hose.Pull the right side of tf the bumper out more to see the alternator. You do not have to remove air con pipes, just un-hook any hangers.You need a 17mm socket and power bar to remove the serpentine belt then you undo the 2 bolts attaching alternator to motor and the 2 elecric cables to the alternator.

Make sure your tire is inflated properly. Jack the car up and spin the tire and check that you don't have a bent wheel. after that bring it in to a tire shop and have them pull the wheel off and put it on their balancing machine. It may be out of balance or have a broken belt in the tire

Sounds like it's time for a new clutch. Get it fixed as soon as possible, if you keep trying to drive it you can wear down what's left of the clutch and damage the internal plates.

It's possible the broken muffler could cause a misfire. Your engine is expecting a certain amount of back pressure from the exhaust. If that back pressure isn't there things may not ignite properly. It's also possible that the hole is messing with the expected gas ratio in the exhaust and the emissions control system is trying to correct it by changing the fuel/air mixture and causing a misfire.

On the side of the transmission.

Check for code I'n glovebox.

The biggest problem with intermittent problems is getting them to occur.It seems that your trouble is sticking around,and maybe you need to just give in and have it flat-bedded to an Audi shop(hopefully the ride on the truck will be gentle enough that the trouble won't clear itself).

is it just the instruments that are acting up? if so thats probably a bad connection somewhere that, when in a certain temperature zone, say from 90 degrees to 130 for example, doesnt have enough current but when heated, regains the current. but if you mean "auto box malfunctions" as in your automatic transmission does not work, then its time to have some pros take a look at it.

Yes you need the tool.

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems.
