Megane II electronic problem...

[Toaster Pilot]

Yes I know they all do that sir etc

Got a 2003 Megane II that sometimes has the dash light up like a Christmas tree - ABS, driver seatbelt warning, rear fog light telltale etc. All on and flickering like there's a bad earth or something like that.

Turning the ignition off and opening the door so the dash backlight goes off and then turning it back on seems to sort it out

Any ideas? It'll be broken for parts if it's anything terminal

I'd guess something isn't earthed properly or is intermittently earthed which shouldn't be.

Had a friend who had all sorts of electrical problems with his and it turned out to be an earthing problem somewhere really weird like in one of the rear light clusters. Only Renault could design a car where a fault in one of the rear lights causes the windows to all open every time it rains.

Does sound like an earth problem. As you must know these cars are notorious for these faults. All the Peugeot/Citroen and Renault cars seem to suffer from these electronics peculiarities. Excellent engines fair mechanics terrible electrics. I would try using the type of electrical component cleaners on the accessible joints and check and clean the earthing. No guarantees, but Good Luck.

Industrial size can of contact cleaner coming up then

Its unlikely it's anything terminal - youll just be chasing warning lights round the car for a while
