While I'm on a roll I thought I might as well post this problem, like most on this car they are long running and to have any chance of offloading the nightmare I have to get them sorted.
At least once every drive I will get the flashing handbrake not working sign on the dash, sometimes if I turn the engine off remove the key and start it up again it will go out sometimes for the length of my journey which is great but eventually it will come back on again.
Last week while driving back from my Mum's the handbrake started applying itself on its own, this happened a few times until I pressed the lever down and it behaved as normal IE flashing and not working.
I have had a look on ebay and there is a handbrake solenoid and a handbrake module which is the best to change or does anyone know of some other fix for this problem?
