Concerns: PDK control unit Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. A shift rod movement at a shift gate that was not selected can be detected incorrectly on the affected vehicles due to a software error. As a result, fault code "P1767 - Hydraulic multiplexer fault" can be stored in the fault memory of the PDK control unit and the PDK transmission can switch to the reduced driving programme until the ignition is switched off and on again.
