Hi I am working on a DIY Haldex controller for my C30 AWD and would like to display some custom text in the DIM. Tried all the CAN IDs and data sending options that I could find (mostly for P2) but nothing worked. My car does not have PHM so I can't sniff the CAN to find the correct IDs and message ...

I have successfully cracked the pin on 2005 V70, read the flash and changed the conf to disable fourC. Is there a tool (freeware or I can also support) to write CEM for P2 apart from Vdash, SMOK etc?
