I have an intermittent fault on my 51 plate C220 with steptronic (?) box.
Very occasionally the gearbox does not change and remaions in a single gear. If I stop the car turn off the ignition and then on again the problem goes. This mostly happens when the car has been standing say over 5 hours i.e. usually in the monring or leaving work.
Any ideas ion what this can be?
Thanks
Steve

This will or should be the speed plate that has failed, about £135 from a good indie that includes new fluid and a filter

And a third suggestion, the battery is weak, and the volt drop on startup is enough to put the gearbox in limp home - a common problem.
