Evening all, recently picked up a 12 plate v60 D5. Absolutely love the car but have an issue or two.
Something funky is going on with the DFP. Once up to operating temp the soot reading jumps up 11-18gand once it jumps past the threshold (22g?) it's starts to regen which isn't hugely problematic but it kills economy because it's regenerating 3x the normal amount. It also means once it starts it won't stop untill I'm sub 5g and cycle the ignition, all this which means frustratingly I've averaged 37mpg over 800 miles. Is this likely to be the DPF pressure sensor or is it something else. One thing I will add is that the spiking is throttle dependant. When off the throttle it will eventually drop back to the correct reading but as soon as I'm back on it it will start spiking again. It's not load dependant as even in 3rd at 70 it will drop when I've lifted off Example pictures Spinking with cruise control on https://ibb.co/tmpyTYQ After stopping https://ibb.co/72Pddfv |
