Replacing your malfunctioning Mercedes Engine Control Unit/Module (ECU/ECM) or Engine Management Electronics (ME) is not as simple as finding a good working used unit for replacement. Due to the onboard Driver Authorization System (DAS) found in your vehicle, this system locks the module to your vehicle! From the dealerships perspective, the only solution is replacement with new OEM parts, and the associated re-programming to re-initialize the module using the Mercedes SDS scan tool.
As a lower cost alternative, MBCluster is able to adapt for re-use, a good working donor ECU as a replacement for your original. Two methods can be employed, the first is a straight copy or clone of the original to the donor ECU. The other method is called blanking, renewing or virginizing, which puts the donor ECU into a "like new" condition, and can then be recoded to the vehicle using the Mercedes scan tool. Both methods involve disassembly of the ECU, and desoldering or interfacing with the vital microchips which store the DAS information. In the clone method, since it creates an identical match, no programming is required by the Mercedes scan tool afterwards.

ECU Cloning:ECU Cloning is procedure where the original ECU contents is copied to the replacement ECU, and allows it to be reused. The Mercedes scan tool is not required to complete the re-installation.
ECU Virginizing:Similar to ECU Cloning, ECU Virginizing is a procedure where a known good, used replacement ECU is reconfigured into a like-new or "virgin" state, also known as "renewing". The ECU can then be used to replace the original, but requires coding using the Mercedes scan tool. Typically this is employed where the original is not salvageable or not shippable.
