anyone know how to reset malfuction warning lights on the '03 c240, I have had the brakes done recently and I cannot figure out how to get the malfuction light to reset.

Did you have new wear indicator sensors installed at the same time?
They look like this:

I believe so if not do I need them installed?

If its your brake indicator thats on that would be the first place to look.
