Vad ca ai scris ca ai schimbat si bujiile. Dar releul de bujii e ok? se stie ca cedeaza la e90 si e60. Sau..., Doamne fereste, bat in lemn, mai poate fi simeringul de la turbo. I.ti mai consuma ulei? Zici ca ai gaurit dpf.ul. Poate softul nu e facut corect. Atasez cateva pasaje luate de pe un forum bmw din UK, in care 'Stan' de la Ecotune, explica posibilele cauze. poate te ajuta. I bet yor remap have wiped off glow plug error together with dpf delete remap. Esy fix flash dde with same software back to stock an check for glow plug faults or just dicconect glow plug cyl no 1 with existing sofftware (its still posible without removing inlet manifold and check if you get that fault coming up in dde fault memory. * White smoke can be caused by: incorrect engine timing, unburned fuel, or coolant getting into the cylinders. * EGR (exhaust gas recirculation) valve, if stuck open, will cause white smoke and will make the exhaust sound funny. The EGR system recirculates an amount of exhaust gas into the combustion chamber to lower cylinder temperatures in order to lower NOx emissions. When you remove the DPF, disable post injection and recalibrate the VNT on the stock file without making any further adjustments to improve the burn, the car is to you or I... visibly smokeless. If you take these engines and do the following - 1. advance the injection to allow the fuel more time to burn(diesel is slow burning)- releases more energy from every drop of fuel increasing performance. 2. Increase injected quantity by both increasing the injector opening time and rail pressure with an aim for the injector to close at a similar time to stock. - this further improves the spray pattern and allows the fuel to atomise in the cylinder more efficiently. 3. Increase boost within the spec of the turbo manufacturers compressor map relative to the increase in injected quantity * Detin un e60 530xd, 2006, si.., in urma cu 2 luni mi.am scos fizic dpf.ul ,urmat de softul aferent. Dupa 2 zile a inceput sa scoata fum alb,cu miros intepator, dar la cald, nu cu motorul rece. Am verificat egr,turbo,injectoare...totul ok. Am citit pe forumuri despre problema nea, am gasit aceste pasaje, le.am copiat, si i le.am aratat baiatului care mi.a facut softul. In concluzie, a umblat iar la soft, rezultatul fiind zero fum alb. Bafta!
