Audi SQ7 CZAC engine code

[Mosanu]

Hello,

I have an Audi with CZAC engine code and the application reports that engine code is not supported.

Is it possible to add support for it, please?

No feedback about this engine, I'm sorry.
Anyway you can try every existing group, maybe some of them is ok for your engine. Also using the free app, just to check that the communication is ok ans some parameter can be read.

Let me know the results

Hi,

Thank you for your answer.

I have the paid app as I've been using it for 4 years on a CRCA.

I have attached a printscreen from the application. The percentage fill level is not correct as at some point was showing more than 100%, I think 108%.

If you need data from the ECU, please tell me as I have OBDeleven and VCDS available.

Best regards!

Hello again,

I have attached two print screens from the app, one is before regeneration started (I don't know "how much before" it was, but I suspect not more than 130%) and one after the regeneration finished.

Can the app be modified to support the CZAC engine code?

As I have said, I have VCDS and OBDeleven and I can get VAS5054, if needed.

Thank you!

You can make some test by playing with the "field regeneration limit" parameter that lets you change the value corresponding to the 100% filling.

It's happened many times that a 30 grams value is the correct one, in fact I added that option just for those cases. Anyway try and let me know what's the correct value for you.

Hi,

Thanks for helping. I will try it and report back. Unfortunately, the car is a vacation and weekend car, so it's not driven that often.

What I noticed from the pictures that I uploaded is that the distance since last regeneration didn't reset. When I parked the car, the post injection was active, so I waited until it deactivated, around 5-7 minutes.

Regarding that the distance is not reset, is it possible that the ECU stops the regeneration before it finishes the cycle?
