Water leak causing odd warning light display - advice needed

    My wife has a 2002 PETROL Mk2 Fiat Punto and it's displaying very odd dashboard warning light display, which is more than likely due to a mystery rainwater leak on the driver's side.

    Early this January, I had to charge the battery as lack of use over the winter had flattened it, and shortly after that, the warning lights started playing up; when the engine's running, the power steering and diesel glow plug (!) stay on, but are 'dimmed' at about 50% of full intensity. This was happening at the time of the MOT test in January, but as the steering function wasn't affected, the car passed. When the key is removed, these lights stay on in their 'dimmed' state for an average of 20 seconds. The really odd thing is that pressing the clock adjust button makes these lights flash on and off in time with the pressing action!

    The battery was charged disconnected from the cars' wiring (but still in situ), and has held its charge fine ever since, so I can hopefully rule out alternator issues. Recently (and regularly) after rainfall, water collects on the driver's mat, pedal tops and most worryingly, part of a wiring loom that can be reached by hand, to the right of the steering wheel. The car did have a rainwater leak last year and I read about water that had collected in the scuttle flowing outside the two drain tubes, and this was addressed by using clear silicone sealant so rainwater can only flow via the inside faces of the tubes and to the ground. I regularly check these tubes for blockages and all is well.

    The car is getting on, but has only done 60k from new, runs really well and my wife would like to keep it going for a while longer if possible - but I'm aware that rainwater can be death to a car - especially if it gets on the wiring, or worse, the ECU.

    Any suggestions?

    Welcome to the forum.
    From the descriptions, yours is UK varient of Punto.

    Would you mind sharing photos of the MID warnings, the water leak location(s) with markings for your suspicions?
