Hello dear elk drivers, I can finally report something positive about my C30 D5. After the 5th or 6th software update my consumption is in the city and short plugs, no expressways at approx. 9L/100. Slowly on the BAB at approx. 6-7 L/100 I also have the consumption of approx. 9L/100 on the BAB at an average of 180KM/h on the route from Stuttgart to Cologne with compliance with all speed limits. The speedometer is also very consistent with the GPS at the Vmax of more than 220. Langs at the beginning I like the car. My FAZIT: Nerv your dealer!!!
