Hi There. This is Frank Sorted that fault on my Megane.After 3 days of solid rain,every light and warning was happening with the car,I even had to stall the engine to switch it off it was unbelivable nothing worked as it should lights flashing,door Hazards locks clicking Flashing etc etc Engine would finally not start.So I took out the Engine compartment fuse box disconnected all the connectors and found that water had got in USED the wifes hairdrier and Heypresto after reassembling the unit Alls Ok now I am not saying it is the penultimate answer to every problem of this sort but it worked for me and probably saved me Hundreds of what a garage would have claimed for ONE hours work which can be done by anyone who is mechanically or DIY minded.You cant get the leads wrong has they only fit in their respective sockets etc Just a bit awkward getting unit out.Good Luck Frank
