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.

SAM module A2165450632 - does it fit your Mercedes CL W216?
This is a used, working Mercedes-Benz front SAM-V module with number A2165450632, hardware number HW A2215451832 and software number FW A2164420700, for the Mercedes-Benz CL W216. You confirm the fit with the ZB number on the label of your old module - if in doubt, we will check it before shipping.
SAM-V system - managing the Mercedes-Benz electrical installation
The SAM-V module A2165450632 is part of the electronic body control system in the relevant versions of Mercedes-Benz cars.
SAM (Signal Acquisition and Actuation Module) processes signals and controls the electrical circuits assigned to it. Depending on the vehicle configuration, the module works together with other control units and equipment.
A correctly matched electronics version matters for communication between modules and for the proper operation of the functions it controls.
Numbers A2165450632 and A2215451832 - what the markings mean
The label of this module carries three important numbers:
- A2165450632 - number of the complete module (ZB).
- A2215451832 - hardware number (HW).
- A2164420700 - software number (FW).
These numbers identify different elements of the unit and should not be treated as three independent, automatically interchangeable part numbers.
When choosing a replacement, compare first of all the complete module number and check that the hardware version and vehicle configuration match.
Electrical equipment not working properly - diagnostics before replacement
SAM module faults can cause problems with selected electrical consumers, communication errors or malfunctions of body systems.
Similar symptoms can, however, come from damaged wiring, fuses, relays, connectors or an incorrect power supply.
Before replacing the unit, we recommend running diagnostics and checking the stored fault codes.
Replacing the SAM module and coding the equipment
After fitting a replacement module, coding or configuration according to the car's equipment may be required.
On Mercedes-Benz vehicles this is done with suitable diagnostic equipment, such as Star Diagnosis or Xentry, depending on the model and year.
Before buying, agree with your workshop whether the selected module can be correctly matched to the car.
