Mk7 VW Golf, Sportwagen and Audi A3 TDI forums
I have a 2015 VW Golf TDI SE. I bought it used about a year ago. When idling, the average consumption wouldn't go down. Now it goes down. For example, just now, I drove until a number was displayed (22 mpg). When idling at a traffic light for a few minutes, it dropped to 19 mpg.
