2009 V6 TOUAREG TDI STRONG FUEL OR EXHAUST SMELL
Several months ago had over whelming fuel smell in cabin. repair shop
diagnosed & replaced oil pressure switch, leaking fuel injectors & seals,
cabin air filter & cleaned as much of fuel from engine surface as possible.
Smell abated some then returned. Repair shop says no leaks after
performing a smoke test which revealed only very minor exhaust leak
towards back of vehicle. They said it would not cause the smell. Car runs
perfect with no other issues. Keeping heater fan set to recirculate vs drawing
in outside air helps keep smell out of cabin, but still strong outside after
driving long enough to warm engine up.
