The temp gauge in my s2 is reading close to 90c from startup, infact all i need to do is turn ignition on and it starts to creep up, just wondering if anyone has experienced this one before, car has not been started for about 2 months
sensor at the back of head and in thee water rail are both new

Its the MFTS in the water rail that provides the signal for the temp gauge. Sounds like it could be faulty. Check the pins at the wiring connector first though.

Be wary if you get a new 3 pin replacement. It will read 10 - 20 degrees too high. It is well documented on here.

where is the best place to get one ? plug was wet when i removed it ! wiring to plug is fine as i had replaced the plug/pins last year, i seem to remember having trouble sourcing a new MFTS at the time

Umm....Really? Never heard of that. Several years ago, I replaced my AAN's 4 Pin with a 3 Pin and the gauge readings have always matched the ones from the Autoclimate control. Still comes up to temp at 89 C (ish)(not higher than 90 C, based on an 87 C OE thermostat).

If you need one go genuine only. Ring Pete at Quattro corner. 0121 476 0034. The genuine ones are normally £100 however I got 2 from him last week for £45 each as he has come by some cheap. Think postage is about £5 next day. Good service too
As said, the Meyle ones are not recommended as they read high.
You can measure resistance between T pin and sender body to get an idea of what you'll get on your gauge.
I fitted a JP group sender which reads bang on 90 degrees on a warm engine (resistance was roughly 1100 ohms). The Meyle sender only measured ~900 ohms
Mine was from Pete at quattrocorner and genuine as far as I am aware. Perhaps I will try and measure the resistance when I get a spare half hour. Interesting.....
