Hi, V40 D4 2015 115k km here, anyone knows if the Vacuum controled valve that actuates the flap on the EGR COOLER can be moved manualy? The Electrical valve is giving 20%-50% error most of the time. With car off, the valve sticks open if i push it by hand. But it still closes and have a EGR flow between 0 and 19g/s readings during driving. If the cooler is clogged completly would it still give any flow?
Symptoms are, rpm flutctuation at idle when cold, light aceleration is slow/labored and it will give a big hicup sometimes around 1200rpm in drive, Shifting gears the car is not smooth(manual), tendency to stall in low rpm where it should have more power, even compared to a gasoline engine. Tested the re-adaptation removing the battery, truth is the car drives perfect that first drive. EGR is off on first BOOT, afterwards starts, EGR valve opens as soon as i start the car and does like a Self test that opens and closes the valve 5 or 6 times or something and is there that RPM fail 825rpm to 730rpm drop for a split second and EGR Error above 60%. car has the newest pipe work done. Intake manifold is new, had Swirl motor stuck also...
