Well I have checked everything that could be cousing poor mileage and can't seem to figure it out. Dpf is far from being full, brakes are not dragging, tire pressure is normal, no codes, alignment is spot on,fuel filter is new,been diesel purged, use additives, air filter is new. Golf has 168k on it and was hoping to be getting better mileage as it aged rather then worse. I'm struggling to get 39mpg highway. Mileage did briefly go back to normal when I found the breather hose that comes off the air box was not connected, has not come off this time.
