Any help/nudge in the direction to understanding the output from the regen/if something else needs investigating would be much appreciated.

Also, the EGR values are a mystery to me. What do the % mean?

Hi give it dose of Cataclean I used it on my daughters Q3 which when purchased had only done 12 miles a day for most of its previous life and suffered with this sort of problem, follow the instructions to the letter and the most noticeable thing on her car was the ball of rubbish that shot out of the exhaust during the first cycle drive the car now runs like a steam train and does more miles now so a year later the problem has not reappeared. BTW no such thing as a passive regeneration on these cars that only occurs on cars with early cordierite cored DPFs, Ford, Fiat.

Hi Steve,

Thank you for the suggestion. I've ordered the cataclean and will report back.

My car was running fine, responsive, mpgs were high 70s and no light. I only picked this up from a scan, so it'll be interesting to see if it yields some improvement.

Do you know what 'time since last regeneration 4.287 H" means from the first set of measuring block data?

 

Edit: as a side note, I've only had the car for a few months (driven 3k miles), it has full Audi history and I did an oil change after a week, just because. I only use ESSO diesel and put a shot of Millers Oils Diesel Power Ecomax in with every fill up) as I did with my A4 B8 🙂

Hi the measurement is a over complicated time span since the last regeneration, the bit you are interested in is the code for the particle trap which is telling you that the entry to the core is becoming blocked this won't affect the regeneration to start with but will further down the line, the core of the DPF is a bit like a sieve in its collection of particles and if you get some big bits it will throw that code, the Cataclean removes/melts the larger particles and restores the holes in the core to their former size so it breaths a lot more efficiently, the Millers is good but is only really helpful if doing a lot of mixed driving and you may want to switch to an additive specifically for cars doing a lot of town work as I have had to, there is still no substitute for a long blast on a motorway  every so often, let us know, BTW the Catalan has no cetane booster in it as it simply cleans.

Steve.

[jdragon]

This is really interesting; thanks for the explanation. What is the measurable I need to look at for the particle trap?

Most of my driving to work (3-4 days a week) is 30 miles each way of A roads, and I average 60 mph sticking to the speed limits. Is there a better alternative to the Millers for that?

The cataclean should be here next week, at which point I'll be able put it straight in the tank and run it to work.

Hi the trap has no measurable base it just throws a code when the entry appears to be congested it won't take a lot to trigger this as it works the same as the CAT and that will throw a light and a code because it is only working at %95, the error margin is that small, with regard to the additives  the Catalan will sort out the immediate problem after that you could give Hydra Maximus a go or Archoil 6900 d synthesis a go, I use both and found the Archoil had the edge as it cut the regens down and if you consider as a cab my car is mostly short journeys what I have been using so far has kept it clear for the last 90k of its life so far.

Quick update:

On Friday I did a 40 mile drive, then a few days of short trips, and a 40 mile drive on Monday. Today I drove to and from work (34 mile) and checked the soot values which were:

IDE00434 Particle filter: soot mass calculated 22.48 g
IDE00435 Particle filter: soot mass measured 6.52 g

The car stood idle for ~2 hours then I took my son to football training which is a 10 minute drive of A roads. When I got back and parked the car, the fan was running so I checked and it was doing a regen.

I measured the values just before the fan stopped at:

IDE00432 Particle filter: time since last regeneration 7.547 H
IDE00434 Particle filter: soot mass calculated 11.19 g
IDE00435 Particle filter: soot mass measured -0.23 g
IDE00436 Particle filter: kilometers since last regeneration 367.5 km

Looking at them again, the values had reset for time and kilometres since last regen

Research suggests the regen should happen every 483km/300miles, so this was a little early but the fault code has disappeared.

I'm still planning to use the cataclean when it arrives, and will likely monitor this over the next few weeks to better understand what is happening.

 

[Steve Q]

Please keep us posted on how you get on with the catclean when it arrives 🙂

Not cataclean yet but I did my usual 34mile (x2) trip to work today and hooked up the VCDS to look at this again.

The error code has not returned and values as follows:

---------------------------------------------------------------------------------

Wednesday,20,April,2022,19:10:25
Mileage: 114294km-71019miiles

  IDE00430-ENG57549   Particle filter: field regeneration request status-Bits 0-7 0 
  IDE00432   Particle filter: time since last regeneration 1.322 H
  IDE00434   Particle filter: soot mass calculated 9.49 g
  IDE00435   Particle filter: soot mass measured -0.67 g
  IDE00436   Particle filter: kilometers since last regeneration 105.8 km
  IDE06059   Particulate filter: oil ash mass 27.4332197 g
  IDE06060   Particulate filter ash load limit 80.000 g
---------------------------------------------------------------------------------

It looks stable currently.

I wonder if there is any possibility that the initial error was caused by some build up being dislodged(?) since the car has been moving again, and I've been using Millers Diesel Power Ecomax (used with my old A4 B8 with good results) which has now been burnt off - too early to tell perhaps.

I've been posting this on the Ross Tech Forum should anyone not be familiar with that resource

Hi the original fault was flagged as the entry flow to the DPF was becoming blocked this is measured by the DPF pressure sensor which has one pipe connected to the intake flow and the other is connected to the out flow, both pressure measurements are sent to the ECU so it can monitor the flow of gas and particles that are being trapped by the DPF, as soon as the readings on the in flow start to drop below threshold status it starts a regeneration to burn off the soot, problem is it only burns enough to start operating again within the prescribed parameters therefore some particles are left in situ, thats where the Catalan comes in as it dissolves the remaining particles in between regeneration so the frequency for that process becomes less as the holes in the core are less blocked as when new.

The ultimate DPF technology was designed by the Italians who were experimenting with Microwave technology for city diesels this gave a 98% burn rate and resulted in near minimum Nox but the project was binned when the European Union went anti diesel, and of course all the nobs in Brussels know whats best for us.

I appreciate the explanation, so thank you for taking the time to reply.

My engineering mind is running wild with this, though at some point I need to accept the system for what it is, and enjoy the car.

From what I can understand, the soot values I'm seeing are OK and will be easy to manage with decent fuel and the millers/Hydra/Archoil with my current driving schedule?

I'll definitely be using the cataclean. Is there a recommended frequency for using it?

Hi they say to maintain optimum results use about three times a year and with regards to the other additives I have used them on my last three cabs racking up some 750,000 miles and never had to have a DPF van when the last one got to the near solid volume because the wonderful fifth injector had packed up a new injector and a forced regeneration sorted that out, my other cab before that got plugged in at 270k by my neighbour so he could check out the latest Bosch software his boss had got him, he remarked that it was all pretty good for the miles especially as I must have had a new DPF recently, WRONG it was the same one it was built with, he looked shocked and explained the car was only showing  2% soot loading and 4% ash, I would definitely give the Archoil a go.

Steve.

[jdragon]

That's a very convincing recommendation.

Is this the correct version?

I have the cataclean and instructions say "remove seal" but there isn't one.

The seal/foil insert in the lid is damaged because I picked at it to see if the seal had popped off in the post, but there is no chance that could've happened.

Is this normal?

There was no other seal on the bottle securing the lid or contents.

Hi thats fine its the latest Hazchem regulation packaging with the seal integral to the cap, please note the raised lip on the bottle this allows you the luxury of re sealing the bottle if you don't use the entire content the original peal off seal wasn't very good when trying to preserve the remainder of the bottle and as you have the latest type of bottle at least it proves its not old stock.

Would there be any advantage in emptying two bottles into 30 litres of fuel?

Hi I can't see why not as its not got a cetane booster in it so it won't compromise the the cylinder head temperature as it would with overdosing with the other fuel additives.

Steve.

Hi forgot to say run like that for half an hour then top up fuel.

Here's the data from the night before I used the Cataclean:

-----------------------------------------------------------------------

Monday,25,April,2022,20:06:45
Mileage: 114587km-71201miiles

  IDE00430-ENG57549   Particle filter: field regeneration request status-Bits 0-7 0 
  IDE00432   Particle filter: time since last regeneration 5.650 H
  IDE00434   Particle filter: soot mass calculated 22.12 g
  IDE00435   Particle filter: soot mass measured 5.39 g
  IDE00436   Particle filter: kilometers since last regeneration 395.1 km
  IDE06059   Particulate filter: oil ash mass 27.4953320 g
  IDE06060   Particulate filter ash load limit 80.000 g

-----------------------------------------------------------------------

I drove to work in 5th gear so the revs were at around 2000rpm

There are several corners and roundabouts within 0.5 mile of leaving work before I get onto the the A road. I instantly noticed the car was much smoother accelerating cold, so much that I forgot to stop and fill up on my way home 😄

Measured values after driving 86 miles with cataclean in 1/4 tank:

-----------------------------------------------------------------------

Tuesday,26,April,2022,18:25:59
Mileage: 114725km-71287miiles

  IDE00430-ENG57549   Particle filter: field regeneration request status-Bits 0-7 0 
  IDE00432   Particle filter: time since last regeneration 1.049 H
  IDE00434   Particle filter: soot mass calculated 7.55 g
  IDE00435   Particle filter: soot mass measured -2.93 g
  IDE00436   Particle filter: kilometers since last regeneration 64.4 km
  IDE06059   Particulate filter: oil ash mass 27.5283779 g
  IDE06060   Particulate filter ash load limit 80.000 g

-----------------------------------------------------------------------

Looking at the mileage, the car did a regen shortly after starting my drive home, so not stopping wasn't a bad thing in the end.

The soot values are slightly less than when I measure after the last regen, but the last regen was done at idle, and I had done an additional 25 miles before I read the values posted Apr 20, so I cannot say for sure if the soot values were reduced more. The best I could do is check after another 25 miles to see how the values compare.

However, I assume with the cataclean running through whilst the regen was being done, it would yield the best possible outcome in terms of cleaning?

Looking at the mileage, the car did a regen shortly after starting my drive home, so not stopping wasn't a bad thing in the end.

The soot values are slightly less than when I measure after the last regen, but the last regen was done at idle, and I had done an additional 25 miles before I read the values posted Apr 20, so I cannot say for sure if the soot values were reduced more. The best I could do is check after another 25 miles to see how the values compare.

However, I assume with the cataclean running through whilst the regen was being done, it would yield the best possible outcome in terms of cleaning?

Hi with post injection static regens do not work very well as the ECU readings are very mindful of the temperatures involved when standing still [set light to tarmac], my mate burnt a ruddy great patch on his drive doing a forced regeneration on his mondeo which lasted ten mins, the fact the soot loadings etc were down slightly bears witness to the cleaner doing its job as you experienced the now smaller particle mass rushing at the DPF which triggered the regeneration, run it through and then fill up with the addition of another bottle it will only get better, post injection engines generally run a lower soot/ash readings note your maximum allowed ash rating, on the Ford pulse pump assisted   system that could go up to a max loading of 300% it is in engineering terms a more efficient system until the feed pipe blocks or the heater element goes down [frequent occurrence], post injection relies on the timing of injection being retarded therefore allowing very large droplets of heated fuel to go down the pipe and ignite in the red hot DPF core which then burns the soot, pulse pumped merely chucks extra fuel into the DPF and sets it alight with the integrated glow plug in the fuel chamber of the feed unit which is generally better for the cat as its not had to be soaked in diesel, thats where the Catalan really works as it clears the excess build up from pre regeneration over fuel.

From the little data I have over the past 8 or so weeks, it's doing a regen every 290 miles - Google suggests this is normal but I don't know?

I'll happily put another bottle in with my next full tank of diesel. And the Archoil should be here on Friday so I'll add that too.

Hi run the Cataclean through and the fuel down before refilling and using archoil then you will get better data from your readings as to what the Archoil is actually doing 290 miles is pretty good going as mine regenerates about every 200 miles bearing in mind my vehicle does a lot of short stop start duty cycles, I did just over 250 miles today and it had a regeneration on the way home.

Thanks Steve. I'll do exactly that, and keep tabs on the regens, soot and ash values.

I found a TPI about this P2002 00 code I'm seeing. Interesting statement about the clogging being caused by the reducing agent.

If the code keeps returning, I'll have to consider the EGR as the next step.
