Casting marks such as "Elektronik CLCS" and Continental branding confirm the correct specification. This ECU is chassis-mounted close to the rear air suspension valves and airbags.

If in doubt, always match the OEM part number A0034463017 or A0004467817 with your old unit before ordering.

This part was removed from a fully running truck and the suspension system was checked prior to dismantling to verify correct operation. The ECU has been visually inspected; connector pins are straight and clean, and there are no signs of water ingress or physical damage. As an electronic component, further coding or calibration is normally not required when replacing like-for-like, but we strongly recommend installation and any necessary parameter setting or diagnostics be carried out by a qualified workshop with the appropriate Mercedes diagnostic tools.
