W213 E220 2.0D Fumes & Smoke from back of engine

[sutherland]

My E220 brings fumes into the cabin, which comes from visible smoke at the back of the engine. It seems to go come and go with a different note to the exhaust, rather like the sound of an exhaust brake. I can't see any obvious cause. Are there any know issues that might cause this?

What colour is the smoke?

Black I think -- it's diesel or exhaust fumes rather than oil. Smells like fumes from a Webasto night heater or something like that.

Look up the green oring and orange turbo gasket replacement threads, plenty on here to follow, my e350 cdi had the same issue and it cured my problems, the oring stopped my fumes and the gaskets cured the smoke as I believe the car was taking air passed the sensors therefore creating the fueling issue, £30 including postage and a Saturday morning did mine and I'm by no means an expert.

It turns out that the fumes are coming from some of the EGR pipework down the back of the engine, which is going to be a very big job to fix, although the part itself will be inexpensive.

My 2006 220 was getting fumes into the cabin.
there are no bad oil or fuel leaks.
eventually I repaired the seal to the bonnet that let’s clean air into the heater as it had degraded and this cured the fumes.
