    Could be the OSV but it seems unlikely on such a young 7.

    Use a folded paper towel and put it over one of the exhausts and smell it after a couple seconds with the car on idle, that will give you a good idea if its coolant burning.

    Otherwise it could just be condensation the V8's give out quite a lot.

    it does smell funny but not of coolant and the water levels are OK and have never dropped down. I thought it could be some form of condensation but wasn't sure. Thanks for your advice

    Valve stem oil seals. Known problem. Repair kit costs very little, labour will cost a lot !

    Valve stem oil seals or bore wear. Both are known issues on older V8 N62 Valvetronics.

    If it's oil smoke, get rid of it, quick!
