Description
OEM part number A0215451332, a genuine Mercedes-Benz W210 E-Class Automatic Transmission ECU, removed from a written-off vehicle and tested in working order prior to dispatch.
The TCU manages the complete gear selection strategy of the automatic gearbox in the W210 E-Class, switching between sport and economy shift programmes in direct response to throttle demand and measured road speed. Torque converter lockup engagement is controlled by this unit for optimised motorway cruising efficiency, and it coordinates shift behaviour with the ASR traction control system to modulate ratio changes under low-grip conditions.
Failure of the transmission ECU in the W210 E-Class commonly causes harsh and abrupt gear changes at all road speeds, a complete elimination of kickdown response when the accelerator is fully depressed, illumination of the gearbox warning lamp on the instrument cluster, and in persistent cases the transmission entering a limp-home mode with a heavily restricted gear range.
This is a genuine used and tested unit confirming OEM part number A0215451332. Professional installation by a qualified technician is required. Transmission TCU adaptation or a basic settings reset must be completed following installation to fully restore normal gearbox operation.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
