The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

Symptoms of a worn or faulty throttle body
When the throttle body in a Mercedes starts to fail, the most common signs are:
- carbon deposits – rough idle, engine stalling,
- worn throttle position sensor – jerking, fluctuating revs, fault code stored in the engine control unit,
- in electronic throttle bodies: failed motor or gear drive – limp mode, loss of power, engine warning light.
When measurements or fault codes confirm the problem and cleaning has no effect, the throttle body is replaced with one carrying the same number. After replacement, many cars need an adaptation in the engine control unit.
