    When are you smelling this, while on the move or when stationary?

    When was the last time you had a service?

    if fuel consumption has gone up it is possibly the engine temp sensor. keep an eye on your fuel bills. My local audi garage explained the engine temp sensors can fail (only about £12 and they had ten in stock). This fools the ecu into thinking the car is colder than it actually is and drops a bit more fuel in, on a bit of choke as it were. eventually it will cause rough running, not sure what else


    or it might be nothing :think:
