Model Year: As of 2015 up to 2016
Concerns: Front-end electronics control unit
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The DME control unit and front-end electronics are not switched to sleep mode on the affected vehicles when all the following conditions are met:
- Ignition is switched off.
- Filler flap release is actuated.
- Fuel tank readiness is not yet reached because the pressure in the fuel tank has not yet been reduced. The procedure can take up to 150 seconds, depending on the pressure conditions in the fuel tank (warning in instrument cluster indicates “Establishing tank readiness”).
- Vehicle is locked within 6 seconds.
This software error in the front-end electronics prevents the control units from entering sleep mode. As a result, the closed-circuit current draw is too high until the ignition is switched on.
