55198930 CN MJD603.S3 – Opel Corsa D 1.3 CDTI VIRGIN ECU ready for adaptation
55198930CN / 55198930 CN is an original Magneti Marelli MJD603.S3 ECU engine controller used in Opel Corsa D 1.3 CDTI vehicles. The offered module has been professionally prepared, fully electronically tested and supplied in VIRGIN condition, with no immobiliser data from the previous vehicle.
The ECU requires adaptation to the vehicle using a Tech-2 or OP-COM diagnostic tool. The vehicle PIN code is required for correct module programming. Each unit is tested before dispatch and supplied with warranty.
Refurbished and protected ECU housing for 55198930CN
The housing of the 55198930 CN ECU has been professionally refurbished. It has been sandblasted, finished with a new protective coating and sealed with specialist silicone resistant to moisture and high temperatures. This solution provides better protection than the standard factory sealing.
Despite the additional protection, the MJD603.S3 ECU engine controller should not be exposed to direct contact with water. During installation, the windscreen scuttle area and the ECU mounting area should be checked for proper sealing.
