Hello,
During a long drive yesterday (450 miles) I noticed that the water temp gauge, normally showing 90°, was not registering. There were no performance issues and the oil temperature didn't rise above normal. Then after a few minutes, I noticed the water gauge was back to showing 90°. Then this morning, when I started up, the water gauge didn't move showing 0.
Is this likely to be a faulty gauge i.e. sender, airlock in the coolant, loose wire or something else. As I say, performance didn't seem affected.
It is a 1998 A4 with 162,000 miles.
Many thanks.
