Just wonder if anyone has come across this before?
When driving my C3 (04 1.4) gets up to temperature fine and then she maintains there. I have got to change my coolant sensor, I know this. However, sometimes when I go round a sharp corner she has started to go from 3 bars (normal) to two. She will stay at that for about 3 minutes of driving and then go back up to 3 bars.
Not a big issue, just something that I have started to notice.
Has anyone come across this or know what it could be?
