Servus, probably a thread title that you don’t read every day… I’ve had my moose for about 6-7 weeks now – except for a defective generator everything was fine. A few relevant informations about the vehicle: A 2005 S40 2.0D summum, apparently with DPF, 240.000km and auxiliary heating. The problem now is this: I always fill up my car in general. If the tank needle bends slowly towards empty, I see that when the yellow tank lamp lights up I steer towards the petrol station. From the appearance of the yellow lamp I don’t really dare to drive much further (although often still 100km “stretch distance” on the BC stand), because the car starts to jerk and brings less power. (Why always). I associate a jerking with empty tank with too little fuel -> so quickly to the tank. Now when the full tank is then filled up hardly more than 40 liters into the tank – you really fill up at the beginning of the “reserve”, come even 38 liters. At first I thought that the Volvo really only had a 45L tank, which then seemed strange to me. So I looked into the boardbook: “Tank content 2.0D: 53L” Suppose there are still 3-4L reserve in the tank inside – where are the remaining 8 liters of fuel? Do I just not drive out the full reserve? –> Why is the car then jerking (from about the middle red line of the tank indicator?) noticeable? (Only from the specific tank filling level, otherwise the jerking does not occur) I we ate’, you don’t have a magic glass ball – but I would be interested in your ideas and experiences! Small information on the edge: With me it’s called full tanking: the automatic end of the pump + about 0.5 liters.
