Today i already purchased water pump, thermostat, 2 belts, tensioner and d eflection pulley upper/lower hoses. Will put my hand to work on this job when i have a free day off. 100K Miles service interval is making sense however, i would like to replace it before it breaking down; we drive this SAV on highway more than local.
I replaced waterpump, thermostat for retired E53 when it was 75K miles. and I may do the same for this E70.

About Temp. Gauge for the E70, i am learning it from "Cool Hidden Menu". It is very strange!

Thanks again Jeff!

Make sure you got the right water pump since there are two variants, one for non 4zone climate control and one with 4zone. There had been some owners who had waterpump failures at that mileage and model year E70's and it will leave you stranded since it will shutdown the engine to prevent overheating. It already happened to me, my brother and a friend of mine only months apart (we all have '07-'08's). It is also a PITA to replace the waterpump and thermostat (almost no room to get those 2 parts out).
