How to reset the tire pressure/runflat monitor? I just had an heartattack when my gauge cluster turned red and shouted one of my tires had gone flat. I actually had one quite low on pressure but I can't get it to reset the tire monitor.

I got a '07 220 CDI.

 

It should be explained in the user manual. Do you have the tyre pressure loss warning system or the "real" tyre pressure monitoring system (with actual pressure values shown at the cluster)?

In any case you can reset it from the cluster menu.

Welcome to the forum.

 

Only the warning light. I'll have to check the manual, it is in german though so I won't understand it fully.
