Sounds like you have several issues going on. What are the OBDII codes you are seeing. You would need to start with that. Go back to the basics and start with a compression or leak down test. As for the oil light it is not there to tell you you need an oil change it is telling you the engine oil is to low and needs to be checked.

start with diagnosing coil packs and work your way from there.

Oh man, you car is falling apart. CEL, TPMS light, EPC, OIL warning, out of gas....

Start with: how much oil does your car have. Look at the oil level screen on your MMI. Then go get some gas and check your tires. Go to Autozone and have them do a free code scan and lookup the codes (you should also get your own cheap OB2 scanner that talks to your cellphone)

Are these "mechanics" familiar with Audi? After plugs and coils I'd look at carbon buildup.

Oh man please don't say that. I got those codes...

The mechanic said cylinders 1,3 and 4 are misfiring and I need a fuel injector replacement.

The shop that replaced my spark plugs and coils was a Audi specialist dealer.

It sounds like you are in the loop of throwing parts into the car without someone doing the proper diagnostics. It also sound like maybe you have an electrical issue going on and maybe a ECU problem. The mechanic that worked on the car is just fishing assuming the injectors are bad. I believe the 3.2 V6 had a valve carbon build up issue but before you do anything about this I'd go back to the basics. You most likely need to go back to a dealer. I would ask for a compression and leak down test to see what you get. At 90K miles you may be seeing the start to major repairs but with the different codes and warnings that are unrelated I think something in the various computer modules are causing problems. A TPS or low oil or low fuel does not relate to cylinder misfires . Find a reputable dealer.
