Can anyone shed any light on a clicking noise coming from the ECU.

When I turn the key the ignition lights don't come on. When I put a light load on the battery (which is fully charged) the clicking slows down, with a heavier load the clicking stops, but still no ignition lights ... the battery refuses to show any signs of life.

The lights don't come on even though the clicking slows down or stops.

Hass the ECU gone for a burton?

Any advice gratefully received.

Out of desperation I've had the car on charge for two hours and tried to start the engine again ... no change.

So I thought I would check the battery fluid and they're all below the plates, I've now topped up the levels and had the car on charge for an hour.

This time the mystery clicking has stopped and I have ignition lights, this is a good sign, also the starter motor engaged very briefly before the lights faded.

I'm going to leave the car on charge for a few hours to see what happens, fingers crossed.

ECU's don't tick-a relay might-sounds like new battery needed.

Sounds very like a dead cell in the battery - get it load tested.

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
