Hi yeah, same thing happened to our 97plate megane. Took it to our garage charged us £90! All it was some water had got in and oxidized the contacts, just filed them off and cleaned them up good as new. (you have to take the plastic casing off the lights, go in through the boot and there's some screws. then you'll get a board to where the wire's are attatched.) Hope it helps :D
