If TPMS valves are replaced with standard valves, the system will simply come up with a message 'Tyre Pressures not detected'. If the alert comes up a couple of times, and is ignored, the alert is then stored in 'Messages', so shouldn't bother you further.
Alternatively, the TPMS system can also be disabled using ELMConfig.
Thank you for that.
I have it booked in on monday at the dealers in the hope that there will be no issues with the TPMS valves
