there are two speed sensors one is a repairable job the other rarer failure is not fixable (or wasn't as of a few years ago) - it is safer to fit a new one... they are vastly cheaper than they once were... but it is linked to the immobiliser and Merc don't like to sell outside main dealership - plenty on naughty software out there lets naughty people swap data over - I would never bother with a repair myself
it won't be the cause of the slippage issues - if its a V12 you need an overhaul - they only last a few miles if you open the throttle
