    Excessive exhaust fumes in car

    The TDI DSG 170 my wife drives is perfect for her, however unlike any other VAG we have owned (a good number) this has a problem with exhaust in the car.
    These fumes can be either from the car itself or of other vehicles in stopped traffic. Its sometimes better to open a window which reduces the fume.
    Having had a similar problem some time ago which was partly corrected following a service and some replacement part (I really do not remember which) it has happened again . This worries me inso much as all other Audi/WV vehicles we have previously owned were really very gas tight.
    This is due a service now but does anyone have any ideas as to why it would recur???

    An activated charcoal pollen filter doesn't allow fumes in .

    A common problem with the Touran diesel, the supplementary heater lets fumes enter the cabin, there is an exhaust relocation retro fit if it does not already have one but also a heater fault can make problems worse.

    Vile Invention

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Exhaust Manifold ?, Exhaust gasket to turbo clamp ?, hole in exhaust ?, EGR gasket ? could well be any one of these. check out first before you start forking out
