Rover 75 immobiliser fault

This car was towed into our workshop, the customer saying that they just came out one day and it failed to start.

Plugging in our diagnostic equipment brought up codes for immobiliser.

This car is based on a BMW e39 and knowing BMW quite well we were aware of communication issues between the dde (engine ecu) and the ews (immobiliser module).

We gained access to the module and were able to perform a coding of the module with specialist equipment.

The car started instantly and ran fine.
