What did Audi the dealer say when this is the second time it's happened? A good way to tell if the car has had a major service will be to.loook at the air filter or pollen filter as these should be clean.
Definitely worth a shot with the eBay option. Check the feedback though. The steering wheel is easy to remove but remember to disconnect the battery and leave it disconnected for at least 30 mins before removing it.

Beautiful ❤️ my a6 is a similar spec and a year older. My dad bought mine new in 2002 abd I inherited it. Mines done 332k on the original engine and gearbox which have never been rebuilt. 90k is very low mileage and should provide you reliable service 🙂
Definitely don't think the brake pad sensors would put it in limp mode. But not sure about the oil level situation. Is that down to a sensor I wonder? If so then hypothetically it could be this.
