Using VAGCOM to log Haldex activity?

[Westy]

Does anyone know if it's possible to log the haldex activity using VAG? I'm interested in understanding when the hadex unit is engaging the back wheels.

I can't see anything obvious in the label file Wes.

Damn it! That's a shame. I wonder how Audi/VW diagnose issues with the Haldex system?

Thanks for looking for me Stu

[VRStu]

I only checked the Haldex lable file. It's possible that it's in another file, maybe ABS or ECU. Also possible that VAS has some functions we don't.

Thanks Stu. I checked the label file for the ABS and there is a block for "transmission" and "AWD".

I think i'll try emailing Ross-Tech and see if they know anyway of doing it.

What sort of issues are you trying to look at here?
