Bluetec.

HI, i have an W211 bluetec nad i want to know how bluetec works on my car, how regeneration process works and i want to know if i have to replace my bluetec filters, DPF or smth else because i have now 110.000 miles. pls I have searched on forum for bluetec i have took some informations but not what i really need to hear from you guys. Also i have some leak of power... when i'm stopped and i kickdown my throttle the car 0-100 time is 9 sec, while she is accelerating in first gear, 600rpm to 2000-2200 rpm is to slow very slow...is this a problem?

The dpf are regenerating by long highway drives with the coolant temperature above 80C. If below 80C, check the thermostat. Try that first. Then there are regeneration solutions and physically cleaning the dpf, which I lack the experience. Search this site for more information on dpf regeneration and diagnosis. Also check the warranty -- it still might be active.

do a search with using cdi instead of bluetec. the W211 did not the urea bluedef and commonly listed as cdi. I recall a thread of the problem your car has, but not the details. I don't know if it was mbworld or another benz site. tray googling it. the cat usually will cause higher back pressure. I think there are some ports before and after the cat to measure the pressure.
