Where can I get a reset tool for my service lights? 99'ml430

 

Probably from a Mercedes Dealer, never saw an aftermarket reset tool. Only car I've ever seen with such a device are BMW's and they are only for the oil change counter.

If you talking about you count down for service, intervals on the dash, you can reset that yourself the instructions should be in the owners manual.

 

Not sure about manual, but have seen it on this forum several times.
