No. In-wheel sensors were done away with on most models beginning 2010 (in the USA).

BTW: rubber valve stems = no sensor in wheel

You'll only see direct TPMS on some RS models and the R8.

Wheel speed sensors. It is a flat tire warning.

Also the A8 and S8.

Indirect TPMS works with the ABS and wheel rotation. No wheel sensor transmitters are needed (no expensive wheel sensor transmitters to be replaced as batteries wear out or for a second set of wheels).
