Hi I'm trying to flash my stock vin into a new A50 tcm for my 2011 LML. I read the new tcm and changed the vin in v8 under properties. When I reflash my tcm with new file and read it out again the vin goes back to all zeros. What am I missing ?

You can change it in the V7.5 scan tool.

I've gone into 7.5 and changed it then saved the file. But when I flash it to the tcm it doesn't take the vin. It stays all zeros.

SCAN TOOL not the tune editing tool.

You will need to connect to the TCM with the scan tool

+1 always use the scantool to change the VIN on any PCM, ECM, TCM.
