Ok, apologies if the terminology is incorrect here, but hopefully it'll make sense!
My C2 is getting water in one of the connectors that plug into the engine management system - of the three its the one nearest the front of the car.
Causing the car to cut out /low rev etc.
Its happened three times so far over the last few months. To get the car running again, I simply disconnect the plug, dry it out and I'm off again.
No matter what I do, I cannot see where the water is coming from, especially given that the battery cover also covers this part of the engine as well.
Water on front plug that goes in ecu

Does it smell like engine coolant ? Unplug the engine coolant temperature sensor & check for the same in there. The sensors leak & the coolant can travel up the wire with the help of capillary action.

Not much water on plug but enough to cause engine to cut out . Ain't smelt it . Water is around pins when blown away car works fine for week then water comes back . Water is defo not coming in from top cus all sealed at top so must be wiring or underneath the car ????

I would suggest that you cover the Ecu with a plastic bags mate or some other waterproof covering. Water near the Ecu plugs could cause it to fry the Ecu and that's a bill you don't want !
