If yours is using the same PIDS as the Euro5 1GDs these may work:
DPF buildup (This one is not a standard OBDII code and from reports didn't work on a 1KD Euro5 but give it a go)
Name: PM Accumulation Ratio
Short Name: Soot %
Command: 2138
Header: 7E0
Decode Scheme: Formula
Formula: J*2
Min.Value: 0
Max. Value: 512
Units: %
Notes:
* When PM forced regeneration is necessary, 100% is displayed for PM Accumulation
Ratio.
* If the ratio exceeds 100%, PM forced regeneration will be performed automatically
DPF differential pressure sensor value
Name: DPF Differential Pressure
Short Name: DDP
Command: 017A
Header: 7E0 or 7DF
Decode Scheme: Formula
Formula: ((256 * B) + C) / 100 (twos compliment signed value but not certain how that is specified in App)
Min.Value: -5
Max. Value: 100
Units: kPa
Note: At 3000 rpm (no load), if Catalyst Differential Press is 0.45 or more, the DPF catalyst has
become blocked.
Requested boost (requested MAP value)
Name: Target Boost Pressure
Short Name: TBP
Command: 0170
Header: 7E0 or 7DF
Decode Scheme: Formula
Formula: ((256 * B) + C) / 32
Min.Value: 0
Max. Value: 320
Units: kPa
Notes:
* Inspect while comparing with "MAP".
* With the accelerator fully open, if the actual manifold absolute pressure (MAP) is low
compared to the target booster pressure by at least 20 kPa for 5 sec. or more, a feeling of
a lack of power will occur.
* When the vehicle is driven with the engine speed at 3000 rpm or more and the accelerator
pedal fully depressed, "MAP" is approximately equal to "Target Booster Pressure".
