If you send your PCM out for repair, make sure they are aware of the code you have. Also, there are online places that sell remanufactured ones for good prices. I know because I was in the same situation. LOL And it was plug and play.
It's funny you are the first one I'm replying to tonight. I just had to replace the oil pressure switch on the A4. All I can tell you is this. It should be a 20-minute job. It took 30 minutes to locate it (impossible to see), another 45 minutes to get the connector off without breaking it, and about 2 minutes to replace the sensor. LOL The manual shows it right behind the oil cooler. Well, that's correct, but it is recessed back into the engine block where you can't see it. Ugh!
And yes, the CVTs on any vehicle are known for having problems. The purpose? To meet the constantly increasing federal emission requirements. The CVT helps prevent the engine from revving too high.
Anyway, if you have a chance, let me know how things turn out for you.
