I have a 2016 CC R-Line with 19k mileage, 2 weeks after buying it I have this warning flash up on the dash every time I start the car

TYRE PRESSURE MONITORING SYSTEM UNAVAILABLE

I scanned with CARISTA which says

ABS - 02214 - tyre pressure warning

I took it to a VW specialist who charged me 244 and apparently fixed the problem but a day later its back, I dont want to take it back there to be charged for more work that isnt going to fix it.

Its driving me crazy, Ive done a bit of searching and digging around but cant find anything similar.

Has anyone else encountered this problem?

Im a perfectionist when it comes to my cars and Im absolutely gutted my beautiful new CC is doing this.

Thanks!
