E70 40D n57 EGR problem.
Hey guys! Having some trouble finding problem for X5 40D. At about 2k Rpm on highway speeds i get CEL which disappears instantly, at same time i feel car a little bit jerks on around 1.7-2.2k rpm,happens more often when going slightly uphil, but not everytime.. i changed 2x EGR valve, done adaptions but nothing helps. First EGR valve that i changed was aftermarket one, second is used original, which have been problem free. Codes i get is :
40D4 DDE: Exhaust-gas recirculation controller, position control 4C9E DDE: Exhaust-gas recirculation valve, plausibility 4C9F DDE: Exhaust-gas recirculation valve, plausibility Last two are stuck open and stuck closed. Maybe some people have seen something like this, please show me the right path without spending a lot of money just throwing in new parts.. I can plug Ista if anyone need some data off it. Or could it be that i have too old ISTA version (4.01.21) And adaptation cant take a place? Last edited by Belekaa; 05-01-2024 at 03:31 PM.. |
