It was the last on the list.
Did you have any problems accessing JBBF with that adapter?

I had problems accessing that module with my random cheapo BT adapter I had. Getting the BMWhat brand adapter fixed that issue and made everything work better, which is why I keep suggesting people stop cheaping out on other adapters. Now you need to buy the real one anyway if you want to code that module.
With the BMWhat adapter I can code any modules on my car. With a random OBD BT adapter I can code some, if it feels like it. Not worth going cheap here.
