Smell

[Knipex]

Colleagues for several weeks I have a worm 2013. But I came across the following problem: the smell of exhaust gases in the cabin and outside. I thoroughly examined the entire exhaust system, I could not find a problem. Please for ideas. ps the engine is 2.2 diesel

It could be you need a new pollen filter and also that there is a grommet or something missing on the bulkhead which is allowing fumes to enter the cabin area
