Sorry to jump in , but i am interested to know part numbers and where to buy the silicone intake hoses from ?

Regards Paul

Hi Paul

I bought a 500mm section to cut down (I seen someone else on a thread who had done this).

From what I gather I've got more than twice as much so if you private message your address I'd happily post across the left over section.

Pm sent , very kind of you .

Regards Paul

Hi DrRob, sorry for the late reply. I've ordered the hoses to replace so when they arrrive I'll fit (probably over the weekend).

I told the ECU the DPF had been replaced (given there were no fault codes other than "P259-65 (6C) Diesel particulate filter regeneration frequency - Algorithm based failure - signal has too few transitions/events".

After this, the DPF filter was reset to 0.

Using the IID tool, whilst driving to the motorway to give it a blast the soot rose from 0 to around 15 (from memory as was driving at this point and not recording the levels).

I was on around 1/3 tank with engine at temperature etc and drove for around 25 minutes (10 minutes A roads / 15 minutes Motorway with no stops).

Pulled in for petrol and hooked up the IID again. Soot reading was now 0....

No demanded regens recorded, nor any partial regens.

Driving back the way I came and under same conditions EGR live readings in the region of:

Bank 1: Sensor 1 @ 415°C / Sensor 2 @ 145°C / Sensor 3 @ 320°C
Bank 2: Sensor 1 @ 160°C

The above where whilst accelerating quite hard (circa 2500 to 3500 RPM in sport mode)

Normal motorway miles at approx. 1500mm RPM the DPF pressure sensor voltage on Bank 1 was around 0.79 to 0.82v.

I will upload screenshots when I get chance.

The above retrun journey added around 6.5g of soot, but I'm not sure the reductions are applied / caluclated during the journey or afterwards once you stop?

I'll plug in again tonight and read the new soot levels.

I'm still learning on the IDD tool so once I'm a bit more aufait with the functions I can be more concise. But so far so good.

Hi Range Rover L322 - thanks for the link and further advice, I like the big orange dog anology (it does feel accurate!).

Unfortunately I'm not an engineer (Quantity Surveyor so spend my time counting bricks ).

I'll fit the replacement hoses and get the smoke test as soon as possible then start doing a few more long drives. The live values monitoring will be helpful in spotting trends, I can knock up a good spreadsheet .

@kevinp luckily it was diesel (freudean slip wishing I had a petrol car with no DPF)!

Hi guys, sorry for my еnglish
first I want to say thanks GGDR great job!
I want to say about how I solved the problem with the dreaded Red DPF
because the car driving a very short distance, one day I saw Red DPF
i tried to run reqen DPF using my software, but it was not possible because soot mass was 31g
but in my software, it was possible to replace DPF, I chose to replace with a new one, then I cleaned up all the errors,
started regeneration and went to the highway, after 30 minutes soot mass was 0,1g
once again I am sorry for my english, have a nice day

Regards Sergei

Hi Sergei - ah thank you, glad you have found it helpful.

So can I just check:

- You had Red DPF warning with 31g
- You tried a forced regeneration but it didn't work
- You then 'told' the car you fitted a new DPF
- You then did a forced generation for the second time which worked
- And then it went down to 0.1 gram (which is nothing)

Is this correct?

. Cheers, Greg

Hi GGDR



- You had Red DPF warning with 31g
- You tried a forced regeneration but it didn't work
- You then 'told' the car you fitted a new DPF
- You then did a forced generation for the second time which worked
this correct

when I drove on the highway my computer showed 0.0 gram (because car thought there was a new one)
after the values began to up, and when the value reached 17 gram, I started regeneration,
and after 30 minutes soot mass was 0,1g
I hope you understand me

Great thanks. Your case may prove very helpful to this thread....

What computer did you use?

. Cheers, Greg

You're welcome
I have the best car in the world
and it was a pleasure for me to be useful

I am using this: V159 JLR Pro for Land Rover JLR OBD2 Scanner
if you want i can give you the china seller link

Thx Sergei! Yes a link would be good.

In desperation I have also done a DPF reset myself (with IID) (mentioned pages 15/16 of this thread) but stumbled through and wanted to hear how you did it - especially without an IIDTool.

There is a lot of black art around the DPF's and I have never been clear how a forced regeneration has been done at a garage and with what kit. Yes I know a few consumer-level kits claim to be able to command a forced regeneration, but I have tried two and they haven't worked.

What I don't especially know is how the garages deal with a +30g soot level. I am starting to think the DPF reset is what they do (one mechanic did initially suggest this) and is therefore an option for all HOWEVER I have and will continue to warn that if you do a DPF reset, you do it at your own risk.

Notwithstanding, I have found - and Sergei too - the DPF seemed to be able to take it, they do seem to be reasonably bulletproof rather than made from chocolate.

In Sergei's case and mine, the theoretical soot level reached around 47-49 grams (31g + 17g give or take) and then it regenerated back down to nearly zero.

Mine has been fine ever since and that was 11 months ago - it still regenerates periodically as it should.

One thing I would say Sergei is that you need to find the cause of your high soot. Hoses / air leaks are the common cause.

Any techs / garage mechanics reading this?
Don't be shy, we'd love to hear your inputs.

.

Dear GGDR here is the link to the seller
this is a replica of a dealer scaner

"to warn that if you do a DPF reset, you do it at your own risk" I totally agree with you!

i know my reason why i have high soot, because 2 km a day trip, is too little for regeneration:)
usually i saw a yellow warning light, and there were no problems, only 10 km on the highway and everything is ok
but this time, immediately red warning
but there is always a solution even from difficult situations:)

And this experience today from Ian1275 confirms my suspicion that garages simply reset the DPF to clear the red:

very very important you carry out a regeneration immediately after.
