TPMS Failure

Hi Everyone,

I've searched back to front about TPMS failures but mine seems to be somewhat unique. I very recently put a set of 19" wheels (original Scaglietti 19s) on my 612 which was an upgrade from the 18/19 wheels. Having picked up the wheels second hand I set about putting them on the car to make my way down to the tyre shop as the tyres were shot. Shouldn't be an issue they were Pzero Rossos, so were my 18/19 tyres and so were the ones waiting to be mounted on at the shop.

I checked the sensor readings and all seemed fine. Half way through the way though I got the "TPMS Failure" message. All of a sudden at constant cruising speed. Put the new Pzero Rossos but no luck. I then took my old wheels down to the shop, took off my sensors to swap with what was on the new wheels. Realised mines were orange and those on the newly put on wheels were grey, normal grey just like epoxy.

The TPMS Failure however still comes on despite numerous resets. I've also done a battery down for a couple of hours and still that light is on.

Any ideas would be more than appreciated. She looks far better now but don't see how I may have upset her. Thanks.
