Congrats, you've done well and obviously a lot of km in a relatively short period- the way the diesels seemingly prefer to run. Do you a readout of your calculated DPF ash level? I'd like to know what to expect before a DPF replacement/rebuild.

Which model Coopers do you have? The only ones seemingly available for me (215/65R16) are the CS4 Touring. I currently have Yokohama A-T/S at 50,000km with lots more to go yet, am very impressed but I just don't do enough dirt road (let alone off road) to really justify a full All-Terrain type.

The latest NRMA magazine "Open Road" has a letter from a reader in it - on holiday in a DPF'ed (read it however you must) Navara. I must say they were not happy with first on the road repair bill of $4,500$ I think for a DPF , then another DPF replaced before they got home ? $2,500 and then a turbo or two .... I think the gist of letter was that they were unable to buy premium diesel fuel on their trip in north qld.

The letter did not indicate whether they suspected fuel played a part, or whether mechanics suggested

Hi. I have the CS4 touring. Been happy with the grip and not much road noise. I got 75000km out of the Yokohama.

Thanks Scotty, straight to the top for consideration next time.

Using a bluetooth OBD-II adapter and the Android "Torque Pro" app I've managed to configure a custom PID so I can read the DPF Soot Accumulation Ratio.
The required codes were found at
http://subdiesel.wordpress.com/gener...tended-obd-ii/
You need to go to the Settings, Manage custom OBD2 PIDs, Add custom PID.
The OBD2 Mode and PID is 22114D, Long name "Soot Accumulation Ratio", Short name "SAR", min 0, max 100, scale x1, Unit type %, Equation A, then OK.

What I haven't found on the Internet is the OBD2 mode and PID for Active Regeneration Count. If anyone finds this PID info, please reply here.

NRMA workshop wanted some serious dollars to fix a friends RAV 4 that was in limp mode.
Found the rest code for him ie ignition on off etc on line fixed for nix.
Possibly the numbers quoted where for the NRMA approved repairer and not by Subaru au?

DPF Active Regeneration Count, Soot Accumulation Ratio

I think I found the OBD2 DPF Regeneration Count parameter.

At a service two weeks ago the DPF regen count was 51. That's one regeneration per week for the life of the car.

Using OBDwiz I asked for all PIDs between 221140 and 22119F. The only one near the value of 51 decimal was PID 221157 with a value of 00 34 = 52 decimal.

The Soot Accumulation Ratio (SAR) was 55% before I took the car for a drive down the freeway at 100km/h in 6th gear, just below 1800 RPM. The SAR slowly climbed to 66%, then PID 22125B = DPF Active Regeneration Switch changed from 00 to FF indicating that it had started active regeneration. The SAR was steady for the first minute or two, then progressively dropped down to 0%. Then the DPF switch flipped back to 00 and PID 221157 incremented to 53 decimal. That looks like the right behaviour.

I'm not sure if the Oil Dilution Ratio PID 22114E is working, because it is reading 0% even after two active regenerations. The Oil Dilution Amount PID 221189 is not supported by my car.

So the settings I am using in Torque Pro for regen count are:
OBD2 Mode and PID is 221157, Long name "DPF Active Regeneration Count", Short name "Regen", min 0, max 65535, scale x1, Unit type [blank], Equation A*256+B. The equation may be incorrect - I won't know until it reaches 255 which will be another 4 years.

In summary, I'm monitoring:
PID 22114D, Soot Accumulation Ratio (0-135%)
PID 22114E, Oil Dilution Ratio (0-100%) [not confirmed]
PID 221157, DPF Active Regeneration Count (0-65535)
PID 22125B, DPF Active Regeneration Switch (00=Off or FF=Active)

As reported by others, don't use 6th gear at 100km/h unless you want the DPF to clog up. Use 5th gear instead.
