Hi Macca and welcome to Renault forums, if this problem started after you drove through a flood then it sounds like a short on the electrical components under the bonnet, I would suspect the pencil coils first. If you have the good old Haynes manual it will explain how to remove them. I would remove them one by one and check for moisture. If you see any moisture dry them out as best you can, when a similar thing happened to me I used a hair dryer at a low temp. and gave them a squirt of WD40. Hope this helps, if not please get back to us and I am sure other members will try to help you out
Regards leroy

Hi again, the ignition, or 'pencil' coils sit on top of the spark plugs and are each attached to the cylinder head by one torx bolt. It's just a matter of unbolting them one at a time and pulling them upwards away from the plugs and checking for damp. It's also a good time to check the condition of your spark plugs. If you get stuck we are here to help

The only way to see which coil is faulty is to disconnect the fuel injectors one at a time and see if the engine note changes.Disconnecting the coils in turn is pointless as they're wired in pairs,so you'll never find the faulty one.

Have a search for 'Pencil Coils' as there is a massive amount of info about them on here.:)
