Hello Jan,
in 2023 I ordered this GB made TPMS Sensors for my C6 from Mal-Electronics, a German reseller, and they work perfect.
https://www.mal-electronics.com/shop/ind..._id=560212
These Sensors are programmable to use 315 Mhz (US-Spec) or 433 MHz (EU-Spec) frequencies. Simply send them an email what you need and they will tell you, which sensor type fits to your C5.
Regards
Armin
