C5 X7 Windscreen Wiper Motor Removal

Post by GiveMeABreak »

This guide is for removal of the C5 X7 Windscreen Motors

This procedure will be necessary if replacing the Master or Slave motors when they start acting crazy. There is an ECU contained in each wiper Motor. The master ECU on the driver side controls the slave ECU on the passenger side. It is important to diagnose the wiper ECUs first with Diagbox, before deciding which of the wiper motors is at fault - because the one acting up may not be the faulty one if it is getting incorrect data sent form the opposite ECU.

Recommended Tool

Removing

Prior to starting follow the BSI Reset / Battery Disconnect / Reconnect Procedure to disconnect the battery. This will allow the data networks to sleep and also prevent the wipers from moving during this operation, which they can do when the engine is off if there is a malfunction.
