I'm interested in buying a pre-owned 2016 A7 3.0T Prestige, and was ready to go into my local dealership tomorrow to get the transaction started; however I got a call from the salesman today saying the vehicle is subject to a recall that was announced this week and they can't sell it until they replace some sensors.

I don't see any sign of this recall when I look up the VIN on the NHTSA site - does anyone know what recall the dealership might be referring to?
