Hi , I have a 2003 Range Rover L322 . I have an electrical problem when my wipers fail , my electric rear windows fail, boot opening fails. I have replaced the ECU under driver's seat. I have replaced car battery. The problem keeps reoccurring. Does anyone have a solution for my vehicle?

 

Anthony, I assume by "ECU under driver's seat" that 1) you are talking about the Body Control Module (BCM) and 2) you are in the UK and this is RHD.
The BCM is known for these types of issues, but in the US, that module is under the passenger seat, so just wanting to clarify we are talking about the same module.

Also, if you did replace the BCM (not a seat module), was it NEW or USED? Was it PROGRAMMED? Functions are limited if not programmed and I can't remember if a used one can be installed (VIN Overwrite).

 

Hi , thanks for your interest, my car is right hand drive in Australia. They replaced it with a new one located under driver's seat. The service center just called to tell me the central locking switch on dash is playing up so they will replace it and see if this fixes my problem. Do you have any solutions?

 

It is critical that the Body Control Module be programmed after installation. Is this "service center" a main Land Rover dealer or an independent shop? Can they check if the vehicle is stuck in Transport Mode? Everything that you stated as not working, runs through the BCM, so I think you are headed in the right direction, I'm trying to figure out why the new part doesn't seem to work.

 

Hi , the service center is an authorised Land Rover center. I will pass on your latest information about transport mode. I'm very grateful for your continued assistance.
