CFFD 2.0 TDI 110 HP

Post by S1ngler » Sat Mar 11, 2023 3:15 am

Greetings,
Could someone confirm me if CFFD 2.0 TDI 110 HP engine is supported in newest version of VAG DPF application? I could not find it in supported engines list. I'have found CFFB engine which is very similar but has 140 HP.
When I choose in settings: Custom engine group - Read from ECU I got all readings except for Low Pressure EGR closing (ND). I'm not sure if my EGR has problem (maybe removed and turned off by previous owner) or just VAG DPF application can't read it's values on my engine?

I don't know if it's my problem, but I see a black image.

Anyway, try so set the engine group 2.
As you said, the engine CFFD is similar to the CFFB, probably only a different power version with the same electronic.

Apologies, couldn't be able to see attachment before post was approved. Yes as you said I guess CFFB and CFFD should have the same electronics but just different power, different turbo etc. I had all the readings except for "Low Pressure EGR closing" and on other car which has CFFB engine I had all readings right values. Another thing about this CFFD/CFFB engine DPF measurings - Soot Mass Measured (-2.81g) and Soot Mass Calculated (11.92g). Is it normal to Soot Mass Measured has negative value?

It's an impossible value, but it's what the ECU shows us. I checked with the official diagnostic software, it's the same value.
We don't know what the VAG engineers want to provide with that value, but it seems that when there is a failure in the DPF system, the soot measured value becomes correct while the calculated one don't. This is the only one reason why I keep that value in the app, but if you don't have issues or failures, you can ignore it.

You checked with official diagnostic software and the value for the Soot Mass Measured is -2.81g?

If I understood you well my DPF should be fine because my Soot calculated value is within normal range and Soot measured is negative which is in real life impossible.

No I don't have any issues for now - no check engine light or dpf light on the dashboard. Also I followed your advice and changed to Engine Group 2 in settings, and after that I got measured values for High Pressure EGR closing (not for Low Pressure EGR closing) but different measured values for Soot Mass Measured and Zero (0) for Oil Ash Residue! I'm now tottaly confused...

Update: Meanwhile I returned Settings Custom Engine Group to Read from ECU and again got N/D for Low Pressure EGR closing but this time 0.7g for Oil Ash Residue. I captured state of DPF at 100% just before start of regeneration. Is this 0.7g (1%) value for Oil Ash Residue accurate and good value? DPF has regenerations at 230 miles (345km) in short city drivings. Is it short distance?

Yes I used official ODIS that confirmed negative soot mass measured values.

My advice is to ignore the measured value and check only the calculated one.
You could need to check also the measured value only in case of failure, for exmaple if you see a sudden jump of the calculated value, synthom of some sensor failure.

I don't see your picture, it's an empty black rectangle. Can you resend it?
