Audi 2005 A6 BPP DPF ash level reset

[willystark]

Hi, after physic cutting off, and cleaning dpf on my dashboard still remain DPF symbol. In measuring block I got about 30 ash level, 36 calculated soot, and 0,6 measured soot. Tried to make "stand-regeneration" of dpf, but it was unable to reach temperature, I think cause of low level of soot. I suppose there is need to reset ash level, to tell ecu that there is "new" dpf installed and get rid of this symbol on dash. I tried this way -engine - adaptation - channel 12 - get info that this channel is not accessible, so tried through security code - filled box by "12233" and got "controller refused the key, first attempt error 35: invalid key, second attempt: error 35: invalid key" so access is not locked, just look like it's not valid code. Have anyone faced with that issue?

Once u get this dpf sign, car has to complete one successful regeneration cycle and it will go off...

Have tried to perform "on stand" regeneration but exhaust didn't reach required temp, tomorow will try to do regeneration while driving. Just one question: could it be harder to get required temp if there are few glow plugs faulty?

If you have fault codes, regen is not possible. That was probably the original fault.
