For those who need a better explanation of how to accomplish this...
You need to scan the NETTODAT file once with the triple blink disabled within the gauge cluster (or idrive) and once again with it enabled. Then use beyond compare to scan the two NETTODAT files and find the value that has changed. That value is the HEX value you need to modify to increase the blink count.
Once you've changed it from XX to 37 (or whatever), save the NETTODAT file as NETTODAT.MAN and recode the car using the codeNETTODAT command.
Hope this helps.
