    I own a 15 golf TDI manual trans. Two questions what is the capacity of the DEF tank? An how much DEF does your car use. I am using about 2 1/2 gallons per 2500 miles about 4 percent of fuel usage. Car has a Kerma tune and runes great.

    Nothing in the owners Manual. The capacity is 14.5 litters. Still would like to know how much other people are using. My car uses about 2 1/2 gallons per 2500 miles

    Okay I didn't realize that a tune would effect def usage. Thanks

    If you change fueling and turbo, then DEF either keeps up or not. So your results/number/speculations would be skewed.
