Hi
Yes - I checked the level just after the service yesterday and it has returned to that level.
I went out an hour ago after the car had cooled and the warning light was still on and the level was at least 1 cm below minimum.
After releasing the cap the level returned back to where it was after the service and the warning light went off.
It's not a faulty warning light as the water level is well below minimum. There's different pressure tests show ok and the two garages don't think it's a gasket.
Only one has said that the radiator hoses seem spongy - or more so that they have seen and that there's a bit of give in them.
Otherwise am I faced with an ongoing unscrewing of my radiator expansion tank - would be great if someone could shed some light.
I checked the forum and someone else has reported the problem but there was no solution posted -
