Technical Information
The C218 electrically adjustable front seat uses multiple individual electric motors, rather than one motor controlling every movement.
Depending on its exact mounting position, a motor can be responsible for functions including:
* Seat forward / backward adjustment
* Seat height adjustment
* Seat base inclination / tilt
* Backrest inclination
* Head restraint adjustment on applicable specifications
Mercedes identifies the individual right/front passenger-side motors separately within the electrical seat adjustment system. (Charm)
Electric Seat System Information
The C218 electric seat system consists of several components working together, including:
* Individual seat adjustment motors
* Seat adjustment mechanisms and drive cables
* Seat control electronics
* Seat adjustment switches
* Associated wiring and connectors
* Memory functions where fitted
A failure of one adjustment direction does not necessarily mean the complete seat or seat control module has failed.
Common Symptoms / Reasons for Replacement
A faulty seat adjustment motor can cause:
* Seat not moving in one direction
* Seat moving intermittently
* Motor clicking but seat not moving
* Motor completely silent when adjustment is selected
* Slow or weak seat movement
* Seat becoming stuck in one position
* Unusual noise during adjustment
* One adjustment function failing while others continue to operate
Important Diagnostic Information
Before replacing the motor, check:
* Seat adjustment switch
* Electrical connector
* Seat wiring loom
* Seat control module
* Power and ground supply
* Motor drive mechanism
* Flexible drive cables where applicable
* Seat runners/gears for mechanical obstruction
A motor that can be heard running without corresponding seat movement can indicate a mechanical drive or cable problem rather than an electrical motor failure.
Installation
Installation position depends on which adjustment function this particular motor operates.
The seat may need to be raised, repositioned or removed from the vehicle to gain access.
Disconnect the vehicle battery correctly before disconnecting electrical seat components, particularly because the front seat assembly also contains SRS/airbag-related components and wiring.
Programming / Coding
An individual seat adjustment motor will normally not require separate programming or coding when replaced with an identical compatible unit.
The existing vehicle seat electronics control motor operation.
Important Compatibility Note
Please compare the part number printed directly on your existing motor before purchasing.
Mercedes CLS C218 front seats contain several different adjustment motors. Motors can look very similar but have different:
* Part numbers
* Gearboxes
* Drive outputs
* Mounting arrangements
* Electrical connections
* Adjustment functions
Do not purchase solely by vehicle model, year or “right front seat” description.
Please send us your existing motor number if you require compatibility confirmation.
Condition
Genuine used Mercedes-Benz OEM part.
Normal signs of previous use, removal and storage may be present.
Please inspect the listing photographs carefully for the exact motor, connector, mounting arrangement and condition supplied.
Ideal genuine replacement for a Mercedes-Benz CLS C218 / X218 requiring a matching right front electric seat adjustment motor.
