BMW Installation Instructions

Park Distance Control (PDC) BMW 5 Series E34, E34/2

Technical knowledge of the System is required. Installation time: approx. 4 hours depending on the condition and level of equipment of the car.

General Information

The description of the working procedures refers to left-hand drive models. Various Steps must be carried out mirror-inverted on right-hand drive models.

Wiring

In order to avoid faults, always adhere to the specified wiring paths in the car!

Under no circumstances work with so-called “Scotchlock quick-action connectors” since they can cause faults in the vehicle electrical System!

Take particular care when installing wires in the car to ensure that they are not kinked or damaged otherwise this may cause faults which can only be subsequently localised by extensive troubleshooting procedures. The resulting costs will not be reimbursed by BMW.
