Greg,
You are right... I am also convinced , that telling the car it has a new DPF and clearing the R.P. RED DPF full , is worth a try, providing you follow it up with a good run monitoring the Soot and Temps until it gets to the 18-19g regen threshold and burns back down to a genuine single figure soot level.
Ian’s today must have had 34g + 18.9g actual soot mass before his successful regen brought it down to 8g.

He just needs to find his air leak now and , touch wood, it will be fine.

This is very interesting.

So to clarify the points and some questions that I am uncertain of:

1) We suspect garages "force regen" on a Red DPF Full it is possibly them setting it as a New DPF then doing a regen. This sounds plausible and likely.
2) Is the IID Tool capable of setting a New DPF
3) Will this clear the Red Warning Light?
4) In this case is an IIDTool effectively capable of clearing a Red Warning light? I thought it wasn't?

Best,



.

Yes the IID can tell the ECU you have fitted a new DPF.

Can The IID then clear the red / RP too?
Not in my experience (see pages 15+16).
But that was a year ago and I was fiddling with my then new DA-DPF tool.

Neither Sergei because he used another tool.

But if it happened to me again I'd try using just the IID.
In theory it possibly could now that I am thinking back over it.

I'm jogging my own memory here with a clip from my post on page 15:

Quote:

Plugged the DA-Dongle DPFDR first; I'll post up the manual. It says it has two functions:
Function #1 Clear Settings Engine off, plug it in and it will clear DPF settings.
There's no interface, just some coloured LED and beeps that tell you what's happening. Red warning still on dash. So I tried again. Red still on dash so ran it again. Then thought I'd plug the IIDTool in and I saw it'd reset the soot to zero. Ok, so I thought what if I clear errors with the IID. Which I did and that worked.

I would add that the IID give a hearty warning about resetting the DPF.

. Cheers, Greg

Ian May be able to tell us in more detail how his was reset to zero , .. what tool they used etc., but only when someone does it all using only an iid will we know for definite.

I know this must have been said many times, but what a brilliant write up, extremely helpful, thanks GGDR!

No issues with the DPF on mine, but I'm sure the day may come!

I agree - this thread and the contributors are life savers when it comes to DPF issues.

I am remiss in confessing that I've not had time (due to work) to replace the 4 hoses on my inlet manifold. However, having cleaned the MAP sensor and ensuring that the EGR butterfly is not clogged, and having told the ECU (using the GAP IID tool) that the car had a new DPF. My car has had it's first regenration with soot falling down to 0.8g.

It was on around 31g (from memory) when I first told the ECU there had been a reset.

My earlier posts describe the first journey after that which appeared to be undergoing passive regens and reducing soot.

After a couple of weeks of very short journeys I lent the car to my brother (it didn't have a DPF warning).

My brother had the car for a day and drove for around 100miles mainly dual carriageway and motorway. Quite soon after he got the car from me (20 miles or so in) the soot eventually accumulated to the point of a yellow DPF warning. Unfortunatley my brother did not have the IID tool to masure the soot, however he used the car for a good 50 miles after the yellow warning and carried out around 30 miles of motorway driving bringing the car back to me.

I plugged in the IID tool and seen that there had been 6 demanded regens and 1 successful regeneration during his 100 mile use. The soot had come down to 8.4g. This was a sight for sore eyes, knowing the car was performing regens and clearing yellow warnings having had a red visit dealer warning. All of this without further intervention from a garage / mechanic and all with the IID tool (which has been said before and I endorse further, is a must have tool for an L322 owner).

I used the car for around 20 miles after getting it back from my brother, and having read the soot levels again, the soot was down to 1gr. My driving was steadily around 30 to 50mph on dual carriageways with no traffic so seems like passive regens are working too.

I will replace the hoses as I have the materials, and will continue to report back on this thread.

On another note, I purchased a key blank that needed coding using the IID tool. It wasn't working however Pat at GAP pointed out that I have a more modern ECU module than would be expected for my age of car (My L322 was first registered as an LR1 vehicle probably for a Land Rover employee or promotional vehicle so has some extras that were probably special order). Pat (GAP) have gone out of their way to write a new ECU flash to allow key writing to the ECU I have which was I thought was beyond what could be expected from them and I'm extremely grateful for.

Cheers

Hi all

I’m sure the garage told the ecu it had a new dpf and by default it resets to 0

They removed a sensor and put the aerosol can cleaner in the dpf and let it do what it does

Then went for a drive , possibly to allow the dissolved crap out the dpf.

Then it was at 0.1

£85

I’m sure there was no “forced regen” as it was genuinely full.

It went to 18.9 after about 2hrs and then regen at 640 deg back to 8

They won’t regen unless between 6 and 24 and have above 1/4 tank I recall..

It’s not had a problem since .

I’ve towed a heavy trailer to lydden from York and done about 3k miles since no bother.

It’s booked in to Jas Land Rover this Wed so will see what the root cause is.

I will keep you posted

Hi Guys,

yesterday I got the "DPF FULL - go to dealer" message on my car + limp mode.
My car has just over 200k km (+/- 125k miles) and I've never had any issues with the DPF so far.

I drive my car hard, only 50km before the red message I was driving the car on the German Autobahn at 210km/h (then the limiter kicks in).
I've done some reading on the oil drain mod, but I've never experienced any smoke coming from my car so I don't think there's a problem there.

My guess is that the DPF actually is full because of the mileage on my car. What do you guys think? '17 Range Rover 5.0 Supercharged AB (Sold)

Sudden change.
Check for boost leak , search donut hoses Cheers, Greg

Hi RRD, yes Greg is 100% correct. You've had a sudden change so there's a checklist to go through:

It's probably a split inlet hose or a dirty MAF sensor.
It is unlikely that the "DPF is full" due to mileage. Clean the MAF sensors and then a high pressure smoke test is advisable.

The DPF itself is a filter (made of ceramic I believe) that basically collects soot then gets heated up by over-fuelling and burns off what it's collected. There's not a lot there to go wrong with it and they usually last forever.

The full list pf potential problems is something like this (in no particular order)
Induction System pressure test
MAF sensors cleaned
EGR issue
Turbos checked with borescope
DPF checked with borescope
Injectors
ECU software up to date
Exhaust manifolds have no leaks
Turbo Drain Mod is usually cited but it's not really considered a cause. It's sort of a stock supposed solution to DPF issues but I don't agree that it is often the cause of DPF sooting or the Mod will fix it.
Check Oil Dilution
EGR Sensor


Hops that helps.... Let us know how you go...

Thanks for the help guys, keep you posted!

So I checked the tubes yesterday, and to the naked eye I don't see anything wrong with them. I checked the 4 tubes indicated in red:
