I just bought a 2006 330 CI Convertible and want to pair my iphone. I need to find the pass key. Unfortunately the documentation for the phone operation was missing. I found the instructions on how to pair the phone but need the pass key and do not know how to find it

I think it might be on the TCU as well.

If you have a 2006 E46 convertible with the BMW Assist/SOS button on the mirror, it should have Bluetooth.
Contrary to ANYTHING you hear, there is no button to push for pairing the Bluetooth in the car.
The ULF/TCU module should have the passkey right on it. You might try the last 4 of the VIN, but I cannot say this will work.

I had my 2006 E46 convertible for 4 years and I have never located the ULF/TCU module. It is likely in the trunk, but I did not want to pull all the lining off to access it. You could probably search the net for where the ULF/TCU is located in the convertible.

The easy way is to just buy the BMW Scanner 1.4.0 software from www.xcar360.com and then you can read the Bluetooth passkey and also program your windows and top to close with your keyfob and do some other things.

One piece of useful information to note, when you are looking for parts other than the dealer, tell EVERYONE it is a 2005 not a 2006. Most parts people and parts applications do not realized the coupe and convertible in 2006 is an E46, they always think these are E9x.Very common for people to get the 2006 confused for an E9x chassis.

The tcu is mounted against the rear seat on the left side of the trunk. I believe the passcode is printed on it. It is easy to get too, just pull out the left side and rear seat trim panels

Right, its against the rear seat but the HF (handsfree) code is hidden on the backside so you may need to loosen it or remove it.

I think you are right, you have to unbolt it to see it. I retrofitted bluetooth so I wrote it number down before I installed it

I'll give that a try. What does TCU stand for?

Here's a picture of the TCU (Telephone communications unit) or something like that. The numbers after the "PK" are the "PASS KEY" numbers. Hope this helps.

Fwiw, PA Scanner also lets you program your own passkey. This is what I did to a more easy to remember one in case I get in the same situation in the future.

What & where "PA scanner" did you buy?

there is a passkey sticker on your tcu (actual it is your ULF). your telephone control/communication unit is located in the trunk. on the rear driver side.

I have a pairing button underneath my arm rest and it is required for me to pair my phone initially.

Useful Thread. 9 years later I have an old 2006 325ci and I was tracking down the bluetooth module. Pulled up the lining slightly to the left side of the trunk rear seat hatch, put my phone under and took a pic. It picked up the PK without having to remove all the linings at all.
