Dave, I think you are referring to the slow speed triggering at 100 increasing to the medium speed at 106, am I right?

Then will go back to 105 plus when it hits traffic ... So it seems to do this high temperature thing only whilst driving and when in lots of stop start driving.

There's a problem with your cooling system. It should not need the medium speed at all if it's working correctly as you say here:

You are absolutely right.

Is it normal for the high speed fan to come on regularly in stop start traffic?

No.

See my post no. 3 for possible reasons for this.
