Just had some marks on the rear wheels refurbed. The bodyshop has completely f**ked the job up. They started to flash in the repair area and could match the paint. They then decided without asking to paint all of the wheel using the wrong colour and even oversprayed the M badges. The paint has run in many places and hammerite would leave a better finish inside the spokes.

As you can imagine I blew my top and the bodyshop manager is going to do the job properly.

However, driving back from the bodyshop a light came on which shows what appears to be a flat tyre. I can only presume that the wheels have tyre sensors in an they may have damaged one (pressures are fine). To add insult to injury, the metal caps have also go (bodyshop already replacing).

Does anyone know whether the wheels have tyre sensors and are these in the valves themselves?

Also, are the valve caps specific to the CSL. I never really payed any attention to them.

The tyre warning system doesn't use pressure sensors at all. It measures wheel speeds and references it against the values held from earlier, the idea being that a deflated tyre will have a smaller rolling circumference and therefore indicate a higher relative speed. Check your owner's manual and it explains the reset procedure, after which you shouldn't have further alerts unless you have a deflated tyre, or a faulty wheel speed sensor.

Good luck

Thanks for that. This makes sense. I better check that they have put the correct wheels on the same axle!!
