      Yeah theres a few issues with the car, but this is the main one. Im thinking that when the weight is in the boot it is lowering the suspension and creating a short circuit on the wiring somewhere. But where about?

        I think its most likely the sensor wire that runs from the brake drum/caliper to join the wiring loom on the car. These are constantly flexing with suspension movement which may have caused the thin copper strands in the wire to fracture,making or breaking contact with each other depending on movement. Or the terminal connector has become corroded ,and its this making and breaking contact with movement .

        When i had an abs fault I checked three out of four of these wires. I decided the connector was quite specialised and didnt look easy to disconnect and either clean up or replace without causing possible damage. So I decided to take the car to a garage. They were able to diagnose the faulty sensor without inspecting wires using a fault code scanner. Their own one didnt detect it, but a bloke from an adjacent garage came over with a scanner that did detect it. I dont think most DIY scanners can do it. Needless to say it was the wire I hadn't checked !. On close inspection the wire had been chewed by a mouse!

        With hindsight had I known for sure which wire was faulty I might have gone ahead and replaced it myself. In the absence of a scanner you might be able to diagnose the faulty wire by manipulating it by hand to provoke a fault.

          This makes sence, I'll have to wait for a dry day and check out the wires and conectors, i take it they run along each side of the chassis from the rear wheels.

            You should see the wires and connector easily enough. If you need to remove the car wheel for better access the usual health and safety warning applies -never climb under a car thats only supported on a jack. .

                I believe the fault HAS to be something on the lines of what Bugman says, but do try 'wiggling' the cables on both rear brake sensors to try and induce the problem.
                The only niggle at the back of my mind, is that I would have thought that the fault would appear as you drive over pot holes etc, yet you do not mention what happens when you are driving.

                Regards

                  Unfortunately the weather hear has prevented me from looking at the mo as i have no garage space. I have noticed tho that the light only comes on when the boot is fairly loaded, i will checked the cabling and also the sensors on the rear wheels. The ligh does not come on or flicker going over bumps / pot holes etc.
