Aftermarket rim/tire size adjustiablity in VAG-COM?

[Kruat]

So I just picked up some 19's for a steal, and I've relized my speedo is no longer accurate. I looked up a tire calculator online, and it says I'm 3.1% slow. I'm running a 245/35/19 falken 452. I've also noticed a drastic drop in MPG. On stock wheels, i was getting around 27mpg, now it's 24ish. I believe most of that is due to the extra unsprung weight.

So does anyone know if I can get into VAG-COM and modify a setting to get my MFD accurate? I saw somewhere that you can go in and adjust miles to empty, but have not been able to find out how.

Did anyone else notice a change going from stock 17's to 18's or 19's?

because your speedo is off, your odometer is also off. some of that mileage difference is due to you traveling more than a mile before you odo registers a mile. ...not that this helps you with your problem....
