ive traced the problem to the immobiliser/central locking ecu (situated inside the panel to the right of the accelerator pedal) if you disconnect any of the 2 multiplugs the indicators work normally although you lose central locking and immobiliser..But i have found the indicator relay appears to be earthing through the ecu causing the fault so i earthed each wire on the multiplug in turn and found the black and white wire at the end of one multiplug was switching the indicator relay so i cut the wire and reattached the plug and now i have central locking as well. The remote key doesnt work and probably not the immobiliser but as ive just bought the car i dont know if it worked in the first place, anyway thanks to everybody for their help and i hope this helps somebody else..
