    only by about 5degC at the most e.g. the temp gauge reads 85 instead of 90. Could this cause any problems? I'm not experiencing any, but I just want to know is it a problem waiting to happen if left?

    are you talking about the gauge on the dash compared to that of the Aircon readout? My Saab Tech of a brother say most modern cars average the temp out on the gauge so that is doesnt waver up and down when the fan comes on or under load unless it deviates by a large amount.

    Khufu is correct, if you're looking at block 49 on the aircon this is the actual temp, 51 (and the dash display are averages) I tell you guys don't drive around looking at 49 as you will get scared about whether your car is working right - it varies A LOT and also in stop start traffic gets VERY hot before the fans come on!
