Thanks for the replies, it's a '98 megane, the RAC guy who came out said the UCH was blown. The symptoms are... the immobiliser light isn't coming on, the right indicator isn't working, the right drivers window isn't working, the hazard lights don't come on (and a few other electrical things but not all). To replace the UCH he said i'd need to replace the key fob, locks on doors, immobilser as well. Don't want to have to bring it to a main dealer and spend 100s on it so was hoping to just sell it for parts maybe? thanks again.
