I have a 2001 C class Merc diesel which has just started producing a strange smell. I have replaced the pollen filter and this has not cured it. It is a mild exhaust type smell which is quite nauseous after a while, I have to turn on air recycle to get rid of it, it is worse when you stop and you can smell it when you get out of the car also does anyone have any ideas what it is and no it's not me!
