Hello everyone, look for your experiences and experiences that will help me make a comparison.To the problem, about 6 weeks ago I bought a R280 (petrol) 4×2 short, first registration in 2008, checkbook maintained at MB, at my MB dealer. At takeover he got a new big inspection. The R-Class is a 5 seater, motor 272 with comand and trailer coupling etc. (information due to vehicle weight). According to operating instructions the consumption on the motorway is 8,6-8.8 liters and i m average 63% highway 37% city 10.9l. I have a very gentle gas foot and move the vehicle mainly on the flat land (almost no traffic lights, traffic jams, etc.) and on the highway usually hit with cruise control at 120 km/h rarely even at 150 km/h, no frantic driving maneuvers simple predictive driving. Have now good 3700km behind me with an average consumption of 13.7 liters (calculated by tank receipts and driven kilometers) at good (all 80% highway, 15% land and 5% city traffic. A conversation with my MB seller has of course already taken place the car was also read out briefly (some errors in the memory), supposedly everything normal … stop the usual bla bla didn’t really want to help me get rid of me quickly. I made a consumption trip in the first 14 days after purchase = extreme sneaking, very slow driving almost never over 2000 rpm etc. at approx. -1°C, 95% highway 5% L and s. 280km consumption 12.7litres (calculated as above) So far from the 8.8l. I recently made the second consumption trip at +10°C and according to instructions from MB, all consumers from = no climate, light etc., pure highway ride, start of the measurement with warm engine, refueling at the same tank / position etc. consumption = 10l14,43% above the manufacturer’s specification. The measuring drives of about 500km extreme loops are in my above 3700km with an additional consumption of weni 26% (via manufacturer’s specification) are included. 1. I find that quite a lot or is this a normal consumption for this vehicle? 2. How are your experiences? 3. My guess is that what is wrong with the vehicle, but the error is not stored in the error memory or is not displayed in the short test is also possible? Thanks already for any help / experience. LG CP
