Welcome aboard garymiboy

Best advice would be to study the handbook, the reset is shown in there.

Be aware that the monitoring system only alerts you to changes in the tyre pressure (at least as fitted on the current C Class (W204)). Lack of a warning doesn't mean the pressures are correct.

I discovered this recently when I found an n/s front tyre was low, not sure how long it had been like that. Put it back up to correct pressure and of course then the warning system is telling me there is a problem. When you reset the run flat indicator it will ask you to confirm that the pressures are correct before you reset. If you reset at the wrong pressures it will happily accept those and only warn you of a fault when you correct them!

I understand it does not actually measure pressure but rolling radius of the wheel.

New to forums but I have not seen any mention of sluggish throttle response coinciding with every run flat indicator inoperative warning. I can live with the warning but what else is going on here, no mention in the manual? Had new ABS sensor fitted in May but problem persists.
