Replacing PDK transmission control unit

Information 

All remote controls (keys) are required for teaching a DME, rear-end electronics (rear BCM), electronic steering lock (ELV) control unit for example, or for teaching remote controls (keys).

Remote controls (keys) that are not taught during this teaching procedure will no longer be recognized by the vehicle.

Information 

When the PDK control unit is programmed, the all-wheel drive control unit is also programmed and coded automatically in addition to the DME control unit.

→ Prior to disconnecting the control unit, switch off ignition and remove ignition key.

→ Ensure that the power supply is not interrupted during programming.

→ Connect a battery charger with a current rating of at least → Nominal value: 40 A  to the vehicle battery.
