I asked about this a year back - mine rarely reaches the 90 degree mark. It
normally sits around 75 too. Has done this for 8 years, since new! No affect
on performance or consumption! Only time it ever goes over 90 is after a
decent motorway stretch, then a traffic queue. The fans kick in and you can
actually watch the needle come back down.

Mine is petrol 2.0 JTS though - did you say yours is diesel? Temps might be
different, I dunno - expert please...
