I've produced some custom PIDS for monitoring the Haldex on my 7R. PIDS are Haldex Blockage (% of engagement of Haldex clutch), Haldex pump current, Front left wheel speed, front right, rear left and rear right. You will need a quality Bluetooth or WIFI OBD2 dongle that supports commands like ATAL and ATCRA. Chinese clones probably won't work 😉 . There is an app called "ELM327 identifier" on Google Play Store which will tell you if your device supports above commands.
1) Create a new Vehicle Profile and in the "Very Advanced" part of the Vehicle Editor add ATAL \n ATSP6 \n
2) Download CSV file (link below) which needs to be unzipped and copied to the .torque/extendedpids directory on your mobile.
Personally, I have only used the Data logging on Torque Pro and exported the data to an Excel spreadsheet. I'm not sure whether the dials will work for these??
I've not produced a step-by-step guide yet as I would like some experienced users to have a go first. I expect some of the experts might point out a better way to do this, but I have done a few logging sessions and the data seems to compare well to results from VCDS. More work is needed.
Hopefully people with a good working knowledge of Torque Pro will be able to get it working using my basic instructions, but if you have any questions I'll try and answer them.
