Hallmark Volvo in Stockport know these cars like the back of their hand (independent Volvo Specialist). You're based in Manchester, bring it to them and get their opinion.

Thanks Kev. I think you read the wrong profile though, I'm based in the West Midlands, south of Birmingham. There are a few specialists around me and one with excellent reviews so will consider that once my own garage have reviewed again.
Appreciate all the advice and replies and will update in due course.
The shift down/heavy load is a red herring, it's directly connected to the overheating. I bottomed that out today on a 1 hour drive.
Once the temperature begins to rise, if you back off and drive normally, it drives fine and doesn't appear to dump coolant.
One observation. I reset the trip today and drove for about 55 minutes on mainly rural roads and fairly leisurely with the odd overtake and a 5 minute 70 -80 mph dual carriageway section. In that time average mpg was 38. I thought that was quite low. Could there be a connection or am I being over optimistic on mpg expectation for the D5?
