Audi R8

I have 2012 Audi R8 and the TPMS light keeps coming on and I constantly check the tire pressure and it is not loosing air. Any ideas?

One of the sensors is probably going bad. Take it to a local tire shop that has a TPMS scan tool and have them find which sensor is going bad. It could also be the spare tire is going flat.
