CAUTION:

New software can only be ordered when the control module is installed in the car. VIDA reads off the new control module identity which is required to order the correct software.

The software can only be ordered when the control module is installed in the car.

CAUTION:

Wait 2 minutes after the ignition has been switched off. The main relay must be voltage-free before  the control module can be removed from the car. If the engine cooling fan runs on after the ignition has been switched off, wait until it stops and then wait for another 2 minutes.

CAUTION:

Always  check that the control module and control module box connector pins and sleeves are not bent or damaged. This may have caused the fault.
