With the introduction of a new generation of electronic immobilizers, the calibration between the engine control module and electronic immobilizer is no longer required.
The elimination of the calibration for 6-cylinder petrol engines takes effect with the DMEs MSV80 and MSD80 as of June 2006.
In the case of diesel engines, the change will be introduced with DDE7 as of March 2007.
Engines from M-GmbH no longer have to adjusted to the DME MSS60 as of June 2007.
From this point onwards, DME / DDE or CAS control modules can only be replaced with control modules specifically ordered for each vehicle.
