Had a look at this one a few times, it has 2 exhaust pressure sensors , the readings looked OK, but we swapped a new one in both positions have run a regen back to zero, lasts for a few days then code back in.

The dealer has told him that they would change the EGR and cooler, but couldn’t guarantee it would fix the issue.

Customer tells me noticed no drop in performance, just concerned about EML on. He is using good fuel and motorway driving in a regularly

I would have thought there is software upgrades for this year model? anyone had similar issues?

Were you able to check on MVB`s for ash load?
Maybe if the ash load is too high one can investigate leaking injectors?
No black puffs of smoke from the exhaust?
Engine not noisy/clattering at times?

[h=2]Persistent DPF fault Audi A6 2.0TDi Ultra CNHA eng code coe 19226 or P2002 00[/h]
Had a look at this one a few times, it has 2 exhaust pressure sensors , the readings looked OK, but we swapped a new one in both positions have run a regen back to zero, lasts for a few days then code back in.

The dealer has told him that they would change the EGR and cooler, but couldn’t guarantee it would fix the issue.

Customer tells me noticed no drop in performance, just concerned about EML on. He is using good fuel and motorway driving in a regularly

I would have thought there is software upgrades for this year model? anyone had similar issues?

Thanks Jack. Per an email the OP (Andy) asked the dealer to update the EDC but they said updates weren't avail. We came up with the same 8284 for 04L 906 021 BD after rummaging through the whopping list of TPIs:

1. 2040900/1
2. 2040900/3
3. 2040064/7
4. 2040064/8
5. 2040064/9
6. 2040064/10
7. 2040908/1​

They all use SVM code 01A209 so I'd ask the dealer to apply that update while it is at the dealer getting that EGR Cooler replaced.

Hi Folks,

not a great way to start a first post but anyway..

was there ever any resolution to this issue via software update or otherwise ? Have seen a car with exactly same symptoms, very same EDC software version and similar mileage etc.. DPF seems to be healthy and regen-ing normally and no loss in performance.. seems very like a software issue as the system ages.. dealer was asked about software updates but customer was told none available..

as this thread is only two months old by now maybe it was too early to tell..

I can post logs if need be but they're almost a carbon copy of the logs on this thread..

Thanks and regards,

Owen.
