Description
This listing covers OEM part number A0265459132, a genuine Mercedes-Benz W210 E-Class Automatic Transmission ECU, removed from a written-off vehicle and confirmed in working condition before being offered for sale.
The transmission control unit regulates upshift thresholds and torque converter lockup timing on the W210 E-Class automatic gearbox by processing signals from the throttle position sensor, road speed sensor and gear selector module. This allows the TCU to identify the optimal moment for each ratio change, delivering refined shift quality whether the vehicle is operating under light cruising loads or heavy acceleration demands.
A faulty transmission ECU in the W210 E-Class produces a pronounced delay before Drive engages when moving off from a standstill, jerky or unpredictable gear changes during normal town driving, the gearbox or check engine warning light appearing on the dashboard, and the automatic gearbox entering a restricted operating mode that prevents progression through the full gear range.
This is a genuine used and tested unit. The OEM part number is A0265459132. Professional installation by a qualified technician is required. Transmission TCU adaptation or a basic settings reset must be completed after fitting to restore full gearbox function.
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.
