Hi everyone. Could someone please look at my Vida graph and let me have opinions or suggestions as to possible faults. Initially I was getting limp mode on roundabouts or gradients and after reading these forums decided it was oil level sensor issues. I lowered the oil level and bought Vida dice and did the adaptation and reset the sensor. That fault seems to be cured now however I get limp mode and code 1507 now low boost pressure. It is intermittent and very annoying and testing my patience. I have completed lots of work including New turbo cartridge with new VNT nozzle kit. New MAP and..used MAF ..used o2 sensor ..new intercooler...cleaned EGR and had the turbo actuator reconditioned. I bought the car with an overboost condition knowing I would have my work cut out. The engine runs beautifully when its on form with lots of power after the new turbo but often when under load I get this fault. I also did away with the resonator and fitted a new pipe to do away with the stupid seals. A smoke test showed no leaks so I am running out of ideas now. Im still suspicious of the reconditioned actuator but vida is new to me so could do with some help please. Btw 2010 XC90 D5 185 bhp. The graph is a gentle drive through the gears to a small roundabout then labour out of it in 3rd gear to cause limp mode. Blue is boost pressure ...Green is EGR valve...Black is air mass...Red RPM. Any advice much appreciated thank you ..Alan....cannot attach graph...security token missing
