Water Level Warning Light ?

[Fitzy7375]

Hi,
I am hoping someone could shine some light on a moment of strangeness.
I ran my missus to Liverpool airport on Friday night ( it's about 45 mile from where I live ), I was doing approx 80 mph there and back.
On Saturday morning I got in the LCR and when I started the car it beeped 3 times ( the beep when your low on fuel ) and the light started flashing next to the temp gauge. I kept an eye on the temp gauge all the way and the needle was sat where it always sits about 90. When I got to my destination, I opened the bonnet and checked the water level and the wiring and all was Ok
When I got back in the car to start my return journey there was no beeps and no warning lights and it's been Ok since. Anybody any ideas ?

Also could any body point me in the right direction of a decently priced performance exhaust system ? Loud but not to loud.

Your help will be greatly appreciated.
Cheers

id put it down to a dodge sensor as above
my fuel gauge used to drop once a month after id filled it up, just die, go to zero and no warning light

It's a well known warranty job. They have to replace the entire water reservoir as the sensor is embedded inside it.

Becomming a common fault, the expansion tank only cost about £10-£15 for the tank itself.

Cheers for the advice guys. Now for the exhaust system, anybody any ideas on a decent priced stainless system, fairly loud but not too loud ?
