Update:
Swapped the red/brown wire round on the sensors (except for the one to the Warm up regulator)...
I got the same/normal readings and as usual the red light came on when i hit the magic 114 on mfa readout!
I popped to the mechanics to get my handbrake cables changed and he reckons it could be the MFA chip behind the cylinder block that is faulty (rationale being that the red light only comes on at a certain temp reading)...will try this next weekend, other than that I am bamboozled

On a positive, did the gsf gear linkeage repair kit this weekend and deffo a firmer feel to the gears!
