Default 48 MPG...woohoo!

Today was our first time taking our brand new TDI out on the highway. A trip that was 110 miles long. We never thought it would manage 48 mpg on an engine that's not fully broken in yet. In any case we're happy to be getting this type of mileage on this size car. Just amazing! I can't wait to see what mpg's we get once the engine's fully broken in.

Welcome!

How exactly did you determine that MPG? Did you fill up and calculate or read the MFA(computer)?

As well we love details on here. What kind of terrain? weather? temp?

Thanks everyone!

Here are some details:

2012 Passat SE TDI w/DSG
200+ miles on the odometer
95% highway / 5% suburban driving
55 deg F. Partly cloudy
Mostly flat highway driving with a few miles of a slightly graded mountain pass
Traveling west bound (against head wind) - Not windy today.
Relying on the car's MFA for MPG. Reset the avg mpg before heading out. Haven't filled the tank yet.

Love the car!

48 sounds great, my Passat SEL is on its' first tank, my 22 miles to work is about half highway, dash readout mpg is getting to 41, very promissing. Can't wait to fill up and get the actual. A shame we have to wait so long between fillups. My 98 jetta did about 48, be great to get the same with this bigger car.

Just wanted to make sure you were flying AGL, with that barometric pressure. 48 MPG with the DSG transmission is really good... curious, how fast were you driving, average to get those kind of MPG's? You can get that on the right stalk if you turn the ignition on, then start the motor, then for settings, go to "Consumption 2" with the "OK" button, then push the arrow down button until it gives you your " average speed".

My avg speed according to the MFA was 50mph.

Do you guys think the MFA's on the optimistic side? I guess the real test would be to fill her up and calculate the miles with gallons dispensed.

There's already a long thread discussing this. Maybe this should be merged with it?
My MFD is optimistic, I'm still working out how much, but so far, about 2%...when it reads 50mpg, I'm really getting around 49mpg. i don't have enough fills to think about adjusting it.

To all the veterans, you get the pressure using the VAGCOM if you have one, right? I dont use it often enough to remember.

I think you need to stop focusing on the mpg and break the engine in correctly...mpg shouldnt be considered until the engine is mildly broken...Its important to not baby these engines during the first couple thousand miles...and not to baby it all the time after that either.

If you break it in 50+ will be no problem
