207 1.4 HDI temperature + fuel problem

Hello. Last week, I bought my 1.4 hdi 207 vehicle in 2008 model 200k km. There was a leak in the diesel return hose, we renewed it. Now my vehicle burns between 7 and 7.2 liters. the temperature never exceeds 80 in the city. How can I lower the fuel, of course, in your fuel? Movement never seemed normal to me. I'm waiting for your help

First of all, welcome to us. I wish you to use your vehicle without any accident, good luck. The cold engine increases fuel consumption, as my teacher probably keeps the thermostat defective and always on, the engine cannot warm up and increases fuel consumption. Of course, in which region you live in ankara, if there is a heavy side, it may occur in stop and stop situations. In addition, if you want the fuel to fall, if the maintenance is not done, I recommend that you make the maintenance of the vehicle and use the original parts in the filters or use filters such as high quality sub-industry bosh. Another factor is the pressure pad's condition.

Thank you. I live in Batıkent. I also think from the thermostat. Because I came without stopping from Etlik to Batikent without stopping in light traffic. Since the weather was hot until 90, the day I bought the car. Firstly, I will change the air and diesel filter myself. Maintaining new oil is in good condition. Let's see how much it will matter. But 7 liters is too much for this car. I use it calmly, I don't have to compress the car too much. oguzzkann 2019-11-18 16:25:04

Thank you, Soner, thank you. I hope I will stop by the weekend. I am originally already away from the supplier industry

I would be very pleased if you inform us as a result of the master procedures.

I would have resolved the problems. I learned that the cold weather was not rising, during the daytime in the heat of the weekend. But I will still have the thermostat checked. If we come to fuel, I think I came to the saint of the on-board computer. I filled the tank last night and burned 6.56 liters of diesel at 100 km. Again high, but in the morning and in the evening, if we count the 5-km business-to-home journey with a winter tire (with a cold engine) it is quite normal. I just changed the air filter of the vehicle 20 30 km ago. To find out when the maintenance is done from the pollution in the filter.
