I honestly thought that Volvo intentionally only filled the sump to around 75% to allow a little headroom if the DPF regen process caused diesel to enter the sump? But my knowledge is merely anecdotal!

I'm generally happy to trust electronic gauges (i.e. the fuel gauge) but I don't understand the logic of this particular system... apparently the electronic dipstick gives an average for the last 30kms, however I wouldn't necessarily expect the "add oil" warning to be driven from the same sensor (as presumably an immediate warning needs to given that the level is dropping?).

I'll admit that I'm worried...either the level sensor is playing up or my engine has actually lost oil. Neither are good outcomes!
