DDE inseamna mai exact "digital diesel electronics" ! La tine nu cred ca sunt bujiile de vina daca zici ca ti s-a aprins din mers acel martor , bujiile la diesel folosesc doar la pornirea motorului :blink: Ok! Am cautat pe net ceva informatii despre DDE, ce face si cum face , si am gasit ceva "Fine tuning for fuel injection - the Digital Diesel Electronics (DDE) system manages all engine functions in BMW diesel models. This saves fuel, ensures you enjoy smooth, cultivated performance and helps reduce lowers exhaust emissions, thereby minimising your BMW’s impact on the environment. Common rail fuel injection in BMW diesel engines combines greater fuel efficiency, lower emissions, improved engine sound and significantly smoother running. Digital Diesel Electronics (DDE) supports these important advantages. Digital diesel electronics (DDE) is a system that monitors the position of the accelerator and the driver’s application of pressure to determine exactly when fuel injection is to start, as well as the volume of fuel supplied and charge pressure. This ensures optimum fine tuning for the relevant engine responses under all running conditions. The result of this micromanagement is even greater economy, improved smoothness and a reduction of harmful emissions. The DDE system is also responsible for speed regulation, and gives the electronic immobiliser clearance for ignition when the correct key code has been supplied." Sper sa va ajute cu ceva... Bafta ... :)
