procesul de regenerare incepe cand vrea ecu, nu cand ii dai talpa. DAca il lasi sa termine, si nu opresti, nu ai probleme. El se face nu neaparat la un nr de km, ci mai degraba de la cata motorina arzi.. Circuli mai mult urban, cu un consum mediu evident mai mare, o face mai des. Sa mergi 4-500 de km cu 2500 rpm nu ajuta la regenrarea dpf-ului in nici un caz. Poate ajuta la altceva, dar nu la dpf. Poti sa mergi cat vrei tu, daca procesul nu e declansat de ecu, nu desfunda nimic. cei care stiu engleza, pun jos citatul de cum functioneaza dpf-ul la bmw. Practic scrie clar, ca in timpul procesului, masina nu trage la fel de bine la accelratii partiale ( adica daca nu pui pedala la fund) totodata, daca e automata, cutia va trege singura pe modul sport, in timpul regenerarii. deci la tine radu, daca masina iti trage mai slab din cand in cand, practic atunci face regenerarea. Daca apoi iti trage bine, inseamna ca procesul al reusit. Ce spun colegii se intampla cand procesul de regenarare nu reuseste, si incearga non-stop. Dar daca apoi merge ok, e normal, e in regula. Daca mergi extraurban, si nu sunt -20 de grade afara, torul dureaza 10-15 min. Urban poate dura mult mia mult. "This process, which may last between 10 to 15 minutes, is repeated on a cyclical basis, the frequency depending on the driving style (but no sooner than once around every 180 miles (300 km) and no later than once around every 1200 miles (2,000 km)). If regeneration is interrupted by the engine being switched off, regeneration will be resumed with the next driving cycle. However, to achieve the high exhaust-gas temperature required for successful filter regeneration, the parameters for the quantity and location of injections, together with the air mass (reduction in charge pressure), are modified in the engine control such that their values differ from the normal engine tuning. In addition, the transmission shift points on vehicles with an automatic transmission are adjusted to match those of the S program.Regeneration of the particulate filter always takes place when the engine is at normal operating temperature. In full throttle mode (not kickdown), there is no difference between the engine tuning and normal tuning during regeneration because the exhaust-gas temperatures are sufficient for the deposits in the filter to be burnt off on their own. Even in this driving mode, however, the transmission shift points on vehicles with an automatic transmission are still adjusted to match those of the S program.The perceptive customer may notice that vehicle characteristics, such as response and noise, are different during particulate filter regeneration. These differences are related to the modified engine tuning during regeneration and do not constitute a technical fault in the particulate filter system or the vehicle as a whole.The somewhat delayed response under acceleration, mainly at low engine speeds, results from the reduction of intake air by the throttle valve during regeneration, which does not need to open fully again until there is a significant increase in load. The maximum engine power output available remains available even during regeneration.The modified injection parameters, such as additional post injections, and the increased exhaust-gas temperature during regeneration affect the noise characteristics of the vehicle, especially towards the low-frequency range when the exhaust system is hot. Noises (sizzling) from the exhaust system may occasionally be heard if the engine is switched off during regeneration. These noises are similar to those heard if the vehicle is parked immediately after a period extremely sporty driving. Odours are common when particulate filters on new vehicles undergo their first regeneration, particularly at low road speeds, because coatings applied during production evaporate (also occurs on vehicles without a particulate filter, but at high speeds on the motorway).The observations described are, as stated above, normal for the particulate filter system and do not constitute a fault.The existing quality and longevity risks are increased dramatically if performance tuning is carried out on vehicles with a particulate filter. The calculation models for particulate filter system management stored in the DDE do not work correctly if performance tuning is carried out, which inevitably leads to malfunctions and/or damage. We would also like to point out that performance tuning is generally prohibited by BMW. The same applies to the use of bio-diesel/RME. Their use is therefore not permitted on any BMW EU4 vehicle.
