Z4: Finding Bluetooth Code

This has been a commonly asked question, and I did this today to find my bluetooth code so I thought I'd give it a try.

Difficulty: Easy. If you can change a light bulb you can do this.

Tools required: Something flat (butter knife, flat screwdriver, etc)

Procedure

1. Move drivers seat all the way forward, and tilt the seat back all the way forward..

2. You will see the large speaker grille that goes over the subwoofer.

3. Using a flat head screwdriver or something else flat, gently pry up the subwoofer grill. Go around the edges until all of the clips have come undone. Once you get done, you will see what you see in picture #1

4. Looking at the subwoofer enclosure, you will see an opening on the right hand side (outboard on the car).. This is the hole that you will look into to find your PK code.

5. Using a flashlight and the same flat object you used to get the grille off, move the wiring harness that is sort of on the top right of the hole. You will move it down.

6. You should see something that says "PK:xxxx" which will be a 4 digit number. Write down that number which is your bluetooth code.

7. Put the speaker grille back on and return the seat to it's normal position.

Awesome! I've had my car over a year and havent been able to use the bt because I did not get the code with it and thought the only way to get it was to tear out the trunk (which I didn't feel like doing). With this it took me all of 2 minutes, thanks for the write up!

elwesso: you rock! I have owned my Z4 since Aug '12, and drug my heels about paying the dealer to get my code or tearing out my trunk.
I had 15 minutes to kill this morning before work, so I grabbed a trusty butter knife, popped off the sub woofer grill, and read my PK code, instantly being able to connect bluetooth. The hardest part of the operation was:
1. pushing the wiring harness down far enough in a small space
2. getting my eyes to focus on the small print.

Thank You once again.

Just in case, my number is PK-7273. I'm guessing there are a number of codes out there?

This should be a sticky for as often as people ask. Thanks for the tip! I went the other way and took the trunk stuff out to get the code. This looks like it would be way easier.

elwesso,

Great how-to! FWIW, my dealer (Russell BMW in Baltimore, MD) looked up the code for me for free when I asked.

for what it is worth, if you are close by NJ/NY area, I can check and also recode your bluetooth code using BMW Scanner software

Thanks

I had tried to get at the PW through the trunk but it would have been a lot harder.... this took 5 minutes as advertised. I had a slim plastic trim removal tool that removed the speaker panel without marring it. Damn it was hard to see the last of the 4 digits - but it was possible....

Bluetooth

Do all Bluetooth codes start with PK ?

This might be a dumb question but does the 2.5i have bluetooth capability? I have looked in the area that was supposed to have the code and I couldn't find the code. Much less a label with it on there. I may be over looking it but it seemed pretty easy to find.

RealOEM lists parts for it.
They seem to be pretty good at "parts not listed are not equipped on your vehicle".
Is there a microphone on top of your steering column?
It's the last diagram that says "SINGLE PARTS F HANDS-FREE FACILITY".

It works! Used a dinner/butter knife long enough to make it happen; placed the knife at the top of the opening at 12 o clock and used the top edge as a fulcrum point to push up on the handle, that pushed the wiring harness down....and the small LED flashlight exposed the PK #....wanted to mention the fulcrum point, as there just aren't enough hands to make it all happen w/o doing this (for me)....I am grateful for the post that disclosed this!

If this method doesn't work on your car, don't give up. I have a Z4 with a January 2005 build date. I tried this but the sticker wasn't there. I was sure there was Bluetooth in the car since it had the microphone, BMW Assist, steering wheel buttons and when I searched with my phone it found "BMWxxxx." So I pulled the carpet from the forward bulkhead of the trunk to expose the TCU, removed the bracket with the TCU attached, removed the bracket, and voila', there was the sticker with the pass key on the side of the TCU covered by the bracket. My phone is now connected!

Just to answer this question and fill a bit more info, there are 10,000 codes. 0000-9999. 0000 is the typical default for devices like keyboards, etc. where there are no security concerns. A specific code is assigned when connection control is desired.

Thumbs up Thanks for sharing this information!!!!

I had to go through my trunk. But I found the Bluetooth unit!!!

I had to go through my trunk because a wire harness was blocking the label and the space was too tight to get something to lift it.

Took me about 20 min to remove two plastic screws and maneuver around the felt lining. But I got to the unit. Unscrewed two little bolts and used my phone front camera to take a picture of the label.

My code is 7307

Thank you for all your help. I'm a new owner of a 2006 Z4 roadster.
Very happy I found this forum.

I just went through trying to find my code and I could not get my head, a flashlight and a screw driver to move the cable all in the same space. I didn't want to tear out my trunk so I thought I'd go the dealership and see if they could look it up for me. The "Geniuses" told me the only way was to have the service guys pull out the trunk. So I wasn't going to pay for something I could do myself. I stopped by my local BMW mechanic and he was so excited to see the car he pulled it in took lots of photos and threw it on a lift to do an inspection. He hooked it up to his computer and what do you know, he sends me the code. No contortion or interior removal required. All that he did for free because he's a great guy. He did note because of the mileage the Diff fluid needed to be changed which he did, the ATF system needed a flush coming up, and the water pump is throwing codes. So I am changing my water pump and thermostat this weekend and will have him change the ATF fluids/filter once I hit 100k. Having a good relationship with an Indy mechanic is a huge plus, I highly recommend it. If you are in the Atlanta area my guy is Todd at Bavarian Repair in Woodstock. I can't speak more highly of him.
