Description
OEM part number 7518709, a genuine BMW Automatic Transmission ECU for the E46 3-Series, E39 5-Series and E53 X5, sourced from a written-off vehicle and fully tested before being made available for sale.
The transmission control unit governs the ZF automatic gearbox across the BMW E46, E39 and E53 platforms, implementing adaptive driving style recognition that refines shift timing over repeated journeys based on the driver’s typical throttle and braking behaviour. Professional installation by a qualified technician is required. A transmission TCU adaptation or basic settings reset is required after fitting to complete the repair and restore normal automatic gearbox operation across all compatible platforms.
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.
