Car is:
passat 3b 1,9tdi bls
EDC16U34
03G906021AB
03G906021JQ
SW 394193
I need help with this one. First I don't see maps that are related with DPF, I have downloaded map with mpps.
Secound I have problems with the car, original maps, the car somethimes don't go very well and I get a lot of smoke from the muffler, but this only happes somethimes, not always... I have checked everything regarding the engine and all components are OK.

I have download map from another 1,9tdi bls passat that has no problems like mine
03G906021AB
03G906021AB
SW 380794
compering some maps I see that duration maps is completly different only duration map 0 are same, other maps are same. Can this duration maps be the problem?
Can I upload this SW to my ECU, or make change on my maps to be same as this one?

Thanks!

I know nothing about your passat but I have a jetta (bora) of the same year that had similar problems (lots of smoke sometimes). Mine would mainly smoke a bunch in 1st gear. The fix for me was to adjust the stop on the turbo actuator that limits the travel of the VNT vanes. It seems they were worn and going beyond the normal range and would hang up every so often causing the black smoke. You may not have a VNT I have no idea, but if you do this may help you too.

I forgot to mention. My car does not have DFP, are you sure your car does?

Maybe this happened when your DPF is cleaning( i mean smoking )

guys thanks for replay,
@Atstodd this is happening somethimes, but not only in first gear, I have changed whole turbo but I have same sympthoms as before so I think this is not the problem, I am shure that my car have dpf because I see it.
@ludbe don't know exactly but one of our muffler mechanic did something on DPF but he did't touch ECU. Can you explain me why I don't see dpf related maps in ori file that I have downloaded from car, I have done this with mpps.
