Description
This listing is for OEM part number A0355454132, a genuine Mercedes-Benz W211 E-Class Automatic Transmission ECU, sourced from a written-off vehicle and tested in full working order before being made available for sale.
This module governs the Mercedes-Benz 7G-Tronic seven-speed automatic transmission fitted to the W211 E-Class, applying adaptive shift learning to progressively refine gear change timing based on the driver’s typical throttle and braking inputs. It manages kickdown logic for immediate multi-step downshifts under full-throttle demand and maintains continuous communication with the engine management unit to ensure seamless ratio transitions under all driving conditions.
A deteriorating transmission ECU in the W211 E-Class typically produces delayed engagement when selecting Drive or Reverse from a standstill, noticeable flares in engine speed between upshifts, a loss of kickdown response under hard acceleration, and in more advanced cases the automatic gearbox defaulting to a restricted fail-safe programme.
This is a genuine used and tested unit with OEM part number A0355454132. Professional installation by a qualified technician is required. A transmission TCU adaptation or basic settings reset must be performed after fitting to complete the repair.
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.
