Couldn't tell you but I would honestly stick with a tsi wagon... It'll get under 7L/100km on the highway... It won't be 5L/100km but like I showed, unless you're getting a tdi for close to the price of an equivalent gasser, it ain't worth it for the amount of km you doI do about 33K per year, pretty much all highway. You're right about the 2015 fixed TDIs though. Stupid expensive. Seems the 12-14 TDIs are much less. Although seems like they have more undesirable effects from the fix which may be why.
