Mercedes Actros MP4 Engine ECU MCM2.1 Control Unit A0014469735 A4704460035 Used

Description:
Used genuine Mercedes-Benz / Continental MCM2.1 engine ECU control unit, OEM reference A0014469735 (A 001 446 97 35/001). This module forms the main engine control unit for Mercedes Euro 6 heavy-duty diesel engines OM470 and OM471 fitted to Actros MP4, Arocs MP4 and selected Axor/Atego commercial trucks. It manages all key engine functions including fuel injection, boost control, exhaust aftertreatment and diagnostics within the HDEP EU AC system.

The ECU shown in the photos is the exact unit for sale. Casting and label markings confirm MCM2.1 and Daimler AG / Continental production with Made in Germany identification. Multiple cross references are used in manufacturer and dealer catalogues, including A0014469735, A0014466035 and A4704460035, plus related ECU numbers A0374488933 and A0374488935 used on the aluminium body. These numbers all point to the same family of Mercedes MCM2.1 engine controllers for Euro 6 trucks.

This control unit is designed for 24V commercial vehicle electrical systems and is mounted in the engine bay on a dedicated bracket. It features one large multi-pin main connector plus one smaller auxiliary connector, both clearly visible in the images. Typical compatible applications include Mercedes Actros MP4 and Arocs MP4 Euro 6 trucks from around 2012–2021 with OM470LA or OM471LA engines; some late Axor and Atego models using the same engines may also be compatible. Always verify by matching your existing ECU part number (A0014469735 / A4704460035 / A0014466035) and consulting your dealer or workshop before purchase.

The ECU was removed from a fully operational donor vehicle. Prior to dismantling, the truck was road tested and diagnostic checks confirmed normal operation of the engine management system without stored faults related to the MCM. After removal the connectors and housing were visually inspected; pins are clean and straight and the casing has only cosmetic wear from service. Condition grade B – used with normal external dirt and oxidation but no structural damage.

Professional installation is strongly recommended. In most cases this MCM2.1 ECU will require programming, coding or parameterisation to your vehicle using Mercedes diagnostic equipment (e.g. Xentry). Some workshops may also need to adapt immobiliser and SCR/AdBlue systems. Ensure your installer can carry out the necessary software procedures and complies with local emissions regulations.

This listing is ideal for workshops, fleet operators and truck dismantlers needing a cost-effective replacement for a failed or water-damaged engine ECU on a Mercedes Euro 6 truck.
