If you can get your car to a shop safely, have them run a diagnostic. It sounds to me it's the cpu in your car. I had a car that did the same thing and had to replace mine. Without a warranty, it can be quite expensive though. But, if you haven't already tried, take the positive then negative battery cables of the battery. Leave them off for a couple minutes then put them on neg then pos. Simple I know but might help. Good luck.

The only other answer would be - make sure it says 'D' on the dash. If it says '1' you got manual gears too, so shift stick sideways till it says 'D'.

It seems your Mercedes is in limp home mode. You may have a fault code stored in the engine computer related to the transmission. Is your engine check light on? Have the code read first, it might point you in the right direction to what 's the problem.

Mine had similar prob. With the ABS and Check Engine lights always on. After computer diagnostic test it was discovered to be speed sensor inside the axle. It was replaced and all faults returned to normalcy. I equally changed my rear break pads.

I think something similar happened to me! The shop could not for the life of them figure out what was wrong, so they put in a transmission. The newer transmission had the same exact problem and THEN they discovered it was a computer error, but we were stuck paying thousands for that new transmission.. it was horrible. SO watch out for that! lol

Had the same problem with my C240 and went to a shop and had my transmission done yet problem still persisted, upon research I found out cranckshaft position sensor was bad(these cars are known for that). Changed it out myself and problem solved
