Hi Guys, newbie here. My 2006 Cayenne S has developed a oil drip, unfortunately, it's onto the exhaust under the hood and so is very smoky, maybe even risky. It's on the driver side at the back of the engine near the firewall? . I took two pictures which I hope is clear. I don't want to start taking everything apart unless I know exctly what I'm trying to fix, so I hope you can help. Thank you.
The first pic shows an oil stain on what looks like a thin black pipe down the side of the engine cover. The second pic is of a small torx bolt it looks like it maybe coming from.
