In the coupe the module is behind the rear wall boot liner. I could just about get my hand in with my phone, take several pictures and eventually I managed to take one of the module enabling me to see the code. If the roadster is the same then this is where you'll find it.

You will also need to use the bt button that's in between the seats in the lid of the drop down storage compartment,

Do you mean the code your car asks for when pairing with your phone? If so its either 0000 or 1234 .

Its called the PAK code which is written on the outside of the ULF / BT module and on the front of the comms user handbook. Unlikely to be the default codes 0000 or 1234

You can also read it with INPA

Not on an E86/6. It’s hard coded into the BT module.

The module sits in the boot against the bulkhead/firewall to the passenger compartment. You’ll need to remove some of the carpet trim to get to it.

Well done that man! Do you know if it's possible to initiate bluetooth pairing in INPA also? What would be really awesome would be a screen shot of each menu stage to get there

I dont know if you can initiate real pairing.
You can activate all seperate functions for diagnostic purpose (including pairing mode) but I dont know if you can actuatlly pair a phone then.
Maybe I can test it, although my phone doesnt work with my ULF (2004 ulf doesnt work with android 3 and plus because of the way the bluetooth stack is integrated, but I think it works with iphones). I can pair my phone though, it just disconnects after a few minutes.

Ok, thanks. It was this post https://z4-forum.com/forum/viewtopic.php?f=3&t=102155 that led my to thinking that it might be possible. I couldn't even find the right menu to get to it in INPA, maybe |I have an older version software. It said it couldn't find the ECU when I tried to go into telephone menu.
