    Definitely sounds like a problem, my Passat Estate TDI 115 does around 40mpg all day long, and it's a heavier car.

    If you can disconnect it and drive around with it, see if it makes a difference, if it doesnt then its not that.

    See if you can get the car on VAGCOM, that will bring up any faults if there are any.

    right. check your egr is not sticking open and then check for boost leaks. those two absolutely destroy mpg on the pd lumps
