Tdi mileage issue

[hippyhippy]

My 09 tdi has done around 130k and is up to date on its service schedule, only recently done the major. I've noticed that I only get around 650km for a full tank when previously I would get 750, anyone else notice a drop in economy?

Do you always use the same pump.

Using a "tankful" would be the most inaccurate way of measuring consumption.

Different pumps can have different shutoff pressures which could give that much varation.

I always fill at the same pump and fill it till I can see the level, then I know its the same amount each time.

Agreed, too many variables.

Even the weather will affect your fuel range.
