Hi,
I have a 2007 R320 (140k Miles) with a 3.0 v6 Cdi engine & 7 sp auto box.
For the past month I've noticed a burning oil smell when stationary on a hill. I don't know if the smell only exists when stationary or if when moving the smell isn't brought into the car. I don't seem to have lost any engine oil in the past month and when I smell the smell of oil a couple of times I've jumped out and stuck my nose under the bonnet but there's no smell from there at all. I've had quite a good look under the bonnet and don't see any wet areas, everything likes nice and dry.
I've also had a look under the car once home (not been able to smell the smell so much on level ground - could be coincidence tho?) and I can't really see the exhaust easily but from what I can see there's no obvious oil. The two hills that I'm stationary on, on the way home where I mainly smell this there isn't anywhere easy to pull over and look under the car. I've also smelt the smell on other hills so it's not the hills themselves.
My fear is that oil from the gearbox may be dripping onto the exhaust? Is this possible? Can I check the gearbox oil? Has anyone had similar symptoms? Is there anything I should try to spot?
Thanks
Louis
