So my Mercedes B Class 2015 is leaking oil from this pipe where I’ve highlighted a red circle. What is this pipe called?

Boost pipe. It’s the output of compressed air from the turbo to the intercooler. The other pipe of a similar size a bit to the right is the boost returning from the intercooler to the intake manifold via a throttle body you can see in the picture

That’s great thanks. I’ll get that replaced. It’s strange because I haven’t noticed any loss of power or any other issues aside from the oil leak.

It’s quite usual to see a little oil in the turbo output pipe, but if it’s really oily inside the pipe you *may* have a problem with the turbo. Just saying.

Yeah pretty much normal.

Duno if you can buy the rubber seals by themselves as may just be as simple as changing a rubber seal

All Renault engines do this!
