Coolant light flashing with ignition off
« on: 30 April 2015, 13:30 »
Car is a 1991 Mk2 8V GTi. It's in regular use, but it shares the daily transport with a couple of other cars and doesn't get started every day. There's an existing fault with the MFA/revcounter and dashboard lights not working.

Returning to the car after maybe a week without moving, there was very little battery. It wouldn't respond to my mains charger/booster, so I swapped the battery for another.
As soon as the new battery was connected, the coolant temperature/level light started flashing, even with the ignition switched off. The car started normally, this light kept flashing. I assume the light operating is what's run down the battery - does anyone have any pointers why it's doing this? Until now the coolant light has been one of those which didn't work at all. Coolant level is OK,

Cheers,
Bill.

Oh well, I disconnected the battery while I did some digging. On returning an hour or so later and reconnecting, the light has stopped flashing.
Cheers,
Bill.
