Hi Crasher
I have just bougt a Q7 and the coolant bottle is going down. After a lengthy journey I can smell coolant on opening the bonnet. I have pressurised the system and boroscoped everything. Its all dry, no witness on the shut off valve. V comp;letely dry, no drips coming down from V. The undertray is wet with coolant. No drips. The top of the sump is wet right under that valve you posted. I thinkit must be either the valve or the housing.

Did you get to the bottom of your leak? If this valve is oil pump pressure valve then I guess it cant be that.
thanks in advance
