I'm new to vx, and have noticed that the temp gauge doesnt move whilst I'm on motorway driving between Stirling and Glasgow, however, when in traffic, it'll move and fall between 90 and 0, never going over the 90 mark...

Presumably this is the common thermostat problem, and as such, I wondered if anyone can point me in the direction of somewhere to get it fixed (and for not a lot of money !) ?

Thanks in advance
