I used to average 22 , I ran into another Eco diesel owner and he also averaged 22 , my high was 27 , pre emissions refit, now I average 19 but its winter here ..... keep your tire pressure at the correct level it helps some
I have a 2015 Eco diesel with 130,000 miles .....the check engine is on I have brought for service and was told its the Regen code , garage wasn't a Dealer but a diesel mechanic. He doesn't know what to do , does the Regen system have a life and does it need to be replaced ? If yes what parts...
