AMG Drive Unit U88: retrofit steering wheel buttons
Genuine AMG Drive Unit buttons give you access to compatible vehicle functions from the steering wheel. This retrofit is available for suitable AMG vehicles with V4 or V5 steering wheels, with optional installation at ProDiag in Verden near Bremen, Germany.
Check compatibility before ordering
Your vehicle equipment and steering wheel version determine compatibility. An AMG package alone does not confirm that the retrofit will fit. Please provide your 17-character VIN and, if the wheel version is unclear, a photo of your steering wheel before ordering.
- V4 with a heated steering wheel: The original configuration does not support this combination. A special adaptation must be discussed separately.
- V5 with a heated steering wheel: Code 443 can be supported, subject to the rest of the vehicle configuration being compatible.
Available controls
Depending on the equipment already fitted to your vehicle, the buttons can control drive modes, ESP, the exhaust flap, rear spoiler and Eco Start-Stop. The retrofit does not add functions for which the vehicle lacks the required equipment.
Scope and installation options
The offer covers the selected retrofit with genuine Drive Unit buttons. We use your VIN to clarify whether additional steering wheel parts are required. Registration of the retrofit in the vehicle data card can be requested.
- Installation: Yes – installation at ProDiag in Verden, Germany. The appointment is arranged separately.
- Installation: No – order the retrofit without installation by ProDiag.
Your variant price appears after selecting the steering wheel version and installation option. A shipping lead time is not a confirmed workshop appointment.
Request a compatibility check or installation appointment. Include your vehicle model, VIN, steering wheel version and whether steering wheel heating is fitted.
