fumes in the air vent

Postby Sashica » Mon Nov 23, 2015 10:54 pm

Hello guys
Maybe someone knows, or someone had the same problem.
When the car is still, and the air vent is ON, I can smell exhaust fumes in the cabin.
Since I have a DCI engine, you can only imagine my pain
Is there already a topic on this, or am I the first one to complain regarding this issue?
Of course, any advice is welcome

Seems you have the same problem as mine - on mine it's the corrugated pipe between the egr valve and the manifold that's cracked. It's a known problem (apparently) and there is a modified pipe available (at least on the 106 version), but theirs not much posts on this subject.

I had that problem and it was one of the injector seals leaking. Some diesel was being leaked onto the surface of the engine head block and the heat was vaporising it. Somehow the ventilation was dragging the smell inside the cabin. Check your injectors for any sign of leaks. I took mine to a diesel specialist and got the seal replaced quickly and cheap.

Hope it helps.
