Hello,

I'm trying to connect to the ECU using my cheap ELM327 via bluetooth but for some reason it says it could only connect to the ELM327 but not to the ECU. It tried a bunch of different preset protocols but in vain.

The car is a 2007 9-5 Kombi.

I'm not sure if there's a specific protocol that isn't on the list that I'd need to specify or if there's a maneuver to do before it's activated?

Does the key need to be on the ON position? Does the car need to be running?

If anyone had this issue and managed to resolve it, please share some tips

Thanks in advance!
