Particle filter emergency regeneration Audi FL 2009?

Hello,

I'm having another small issue with my particulate filter. The vehicle is a 2009 Audi 4F 2.7 TDI, which is the facelift model. The car is driving normally, and there's no warning light on. However, the error code in the diagnostic memory indicates "particulate filter overloaded, cannot be cleared" because it immediately reappears. The oil ash content is 0.35, which is within the acceptable range (the limit is 0.46 according to my VCDS). I was planning to start a service regeneration, as described in this forum, using login code 10016, and all the conditions seemed to be met. If I enter the code "11" in the "Encoding II - 11" field, I get the error message "11" is not allowed.

Can someone explain the forced regeneration process for the facelift model? Perhaps the description from the previous model doesn't apply here in this forum.

Thank you.

Hello,

You are confusing the amount of soot accumulated in the DPF with the ash content.
The forced regeneration process is working exactly as described for you.

The article describes when regeneration is still possible.
Okay, I'm ready. Please provide the German text you want me to translate.

Quote:

Particulate filter loading state is below 68g. See measurement block 104, field 3. If the particulate filter loading is greater than 68g, the filter must be replaced, otherwise the filter could become too hot during regeneration and could catch fire!

"Beladung" always refers to the amount of Russian material present in the filter. The biogas is burned periodically in a process called regeneration.
The ash will never decrease but will always accumulate, until the filter eventually needs to be removed, cleaned, or replaced.

Best regards, Rainer.

Hello,

I tried again today. The login isn't working for me. Specifically, with encoding II-11, it doesn't work. Then, with access permission 16, I was suggested the following code: 27971, and that was accepted. Unfortunately, I still couldn't start the regeneration. I opened all the MWB 100, 101, and 102, but nothing happened. At the very bottom left is the block "Basic settings visible," but for me, it remains bright and cannot be clicked. Is this normal, or does the regeneration start immediately when all 3 main circuit breakers are opened?


Best regards.

First, please perform an initial scan, then read the instructions again (check the prerequisites), and save the relevant measurements so that you can post them here later.

Hello,

It's likely that it will then work similarly to how it does with the 1.6/2.0 CR-TDIs. Please check the requirements listed there.

If the soot load is too high, the regeneration process will no longer work while the vehicle is stationary (due to the risk of the DPF overheating), and at even higher levels, it will also fail during driving.

Finding the root cause of why a situation deteriorated to the point where emergency measures were necessary is just as important as successfully implementing those measures.
Except for extreme short-distance traffic, there are essentially only defects or errors as possible causes.

Also, please provide the text you want me to translate from German to English. I will then provide only the translation, without any explanations.

Best regards, Rainer.

Hello,

I will try that. I already replaced the differential pressure sensor as a precaution, and I will also check the temperature sensors. Should I be getting ambient temperature readings there when the engine is cold? My problem is really with very short distances, a maximum of about 15km.

At approximately what mileage does the regeneration process occur in a 2.7 TDI engine?

Thank you.

Quote:

15km maximum

They should be enough.

Yes, when the engine is cold, the temperature readings should be approximately the same. Please also check if the temperature readings are reasonably plausible when the engine is warm.

Best regards, Rainer.

Hello,

Today, I analyzed the data from the MWB 099 temperature sensors after the vehicle had been stationary for about 2 hours, and the coolant temperature was 57 degrees Celsius.

Address 01: Engine Control Module (4F7 910 401 L)

15:13:12 Block 099: Exhaust gas temperature.
0 /min Motor speed (G28))
849.6°C Temperature before the exhaust turbocharger
5.9°C Temperature before the particulate filter.
224.2°C - Temperature after the particulate filter.

What do you think about the values? The sensor before the turbo is likely defective. I'm also not sure if the reading after the DPF is correct, as it's showing 224 degrees, while before the particulate filter, it's only measuring about 5.9 degrees.

Should I replace both of them, or just the one before the turbo?
As I said, there are no error messages (the "full load" message appeared repeatedly before, but it hasn't appeared for the last 2 days, so the error memory is now completely empty), but a DPF regeneration (forced regeneration) is not possible.

They are all perfect for the most important person. Since it's unlikely that all three are defective, I suspect there are cable problems, possibly due to damage from rodents or something similar.

Best regards, Rainer.

I would definitely recommend checking the values again after a longer period of inactivity (at least 12 hours).
After 2 hours, there is still residual radiant heat everywhere, which doesn't tell us much. Sure, the value before the turbocharger is definitely implausible, no question about it.

Hello,

This morning (so, with the vehicle completely cool) and with an outside temperature of 1 degree Celsius, I read the following values again when the ignition was turned on, without the engine running:

Address 01: Engine Control Module (4F7 910 401 L)

11:49:26 Block 099: Exhaust gas temperature.
0 /min Motor speed (G28))
Temperature before the exhaust turbocharger: 849.6°C.
-17.7°C Temperature before the particulate filter.
224.2°C - Temperature after the particulate filter.

"After I started the engine, only the middle value (temperature before the DPF) immediately increased, while the other two remained unchanged. Is it really possible that both sensors are defective, or is it more likely a weasel bite? I haven't had time to get it on a lift for a visual inspection of the cables yet. Unfortunately, my vehicle is not yet listed on Erwin's website. Does anyone happen to have a wiring diagram for the DPF and its sensors?" Engine is CANC.

Best regards.

Hi Luiggi,
Check the Irrwinn catalog under A6, models 2005-2007, RLF (Rear-wheel drive), power transmission, 6-cylinder TDI Common Rail, 2.7L and 3.0L engines. The CANC (likely referring to a specific component) is located there. If you click on the MKB codes, all of them will become visible.
Happy New Year!
Herbert.
