Audi A4 2.7L: Specs, Problems, & More

Hello, I have an Audi A4 2.7 TDI from 2010. The engine code is CGKA. The problem is that the differential pressure sensor triggered an error message. I replaced it. I wanted to perform a DPF regeneration, but unfortunately, I can't access the measuring blocks or the adaptation settings.
"These fields are grayed out. It also doesn't work regarding the access permissions. Currently, the car is running in emergency mode, and I can't perform a forced regeneration. Can anyone help me get it working without having to take it to the dealer?"

Hello,
Perhaps this will help you: a technical article on forced regeneration.

Hello, I've already tried that. But as I said, I'm unable to access the measurement data blocks with my program; I can't get into the fitting section.

Hi,

1. Measure whether the values from the differential pressure sensor are correct (0 mbar when only the ignition is on), and check the plausibility of the values under load. There is a topic about this: https://community.dieselschrauber.org/en/viewtopic.php?t=24222
2. Check the exhaust temperature sensor values for plausibility.
3. Read the article about forced regeneration, which was updated some time ago: https://community.dieselschrauber.org/en/viewtopic.php?t=17091
"Modern control units no longer have 'data blocks' in the traditional sense, but instead use 'extended data blocks' or other functions. The specifics can be determined by performing a vehicle scan."

Best regards, Rainer.

It only has extended measurement data blocks.

Best regards, Rainer.

And how can I perform a factory reset? It doesn't work the way the instructions describe.

Anleitung für DPF Regeneration, Steuergerät mit UDS wrote:

Forced DPF regeneration for 1.6L/2.0L R4 & 3.0L V6 CR-TDI engines (UDS). Sure, here is the translation of the text from German to English: "Background information:" In newer common-rail TDIs, there are two types of DPF regeneration, depending on the soot load of the filter. If the calculated or actual soot mass is below a certain threshold, the regeneration can be performed while the vehicle is stationary or while it is being driven. If the soot mass in the filter is higher, regeneration can only be performed while the vehicle is being driven. Prerequisites for regeneration: Ignition ON. The engine is idling (park position with automatic transmission). Make sure the tank is filled to at least 25%. Coolant temperature above 70°C (see corresponding extended measurement data block). Hood closed. Particulate filter loading status (see the corresponding extended measurement block) within the specified range. If the particulate filter loading exceeds the corresponding limit (see Screenshot below), the filter must be replaced immediately, as otherwise the filter may overheat during regeneration and potentially catch fire! As many electrical consumers/loads in the vehicle as possible should be turned on (e.g., lights, rear window heater, air conditioning). Regenerative braking: Engage when driving at a minimum speed of 60 km/h. Regeneration during driving: Engine speed between 2000 and 2500 RPM, exhaust gas temperature in the exhaust manifold > 700°C. Read the engine control unit's error memory to identify potential causes of errors and then fix them. The regeneration process can take up to 20 minutes. Drive until the filter is as empty as possible (0%). Be careful, as high temperatures can occur in the exhaust system! If the regeneration fails, it's either because the engine was running under too little load (e.g., driving downhill for a long time), causing the exhaust temperature to drop too much (approximately 170°C before the turbocharger, 150°C before/after the particulate filter), or there's another engine fault that needs to be addressed. When regeneration is performed while the vehicle is stationary, and if supported by the control unit, no input is required at Security Access - 16. [ECU Selection] [01 - Engine] [Default setting - 04] Select the appropriate option from the dropdown menu to regenerate. [Ok!Bitte gib mir den deutschen Text, den du übersetzt haben möchtest. Drive until the amount of soot or the volume of soot is as small as possible (0%, 0 ml). Find and observe the corresponding measurement value for this in the advanced measurement data blocks. [Back] [End connection, back - 06]

Which of these points is not possible? Please provide a Screenshot of the VCDS dialog showing the control unit information and buttons.

Best regards, Rainer.

I've tried it several times. Unfortunately, it hasn't worked. It keeps getting interrupted.
But thank you for the instructions.

?

What did the measurement blocks show regarding ash mass/volume and soot content?

Are you getting any information, or was the entire question rhetorical?

The volume was 0.15 liters, and I don't have the rest of the information anymore. I wrote what I had in the scan. I can check for errors again if you like.

I can't retrieve the error code anymore. It had already been taken to an independent repair shop. I would have liked to know why it kept failing for me. I thought the conditions were met. However, the mechanic said that it also failed multiple times at the workshop because certain temperatures weren't reached. I think it was the exhaust gas temperatures. And I believe that was the problem for me as well. The car could then be regenerated while stationary.

Bad luck.

I would have liked to have achieved that too. I'm really frustrated right now.

Well, unfortunately, you haven't addressed any of my questions, and no information was sent.

Then there's no point in speculating about which conditions might not have been met, as they are all listed in my instructions.
