DIY: Disbale X3 seat belt chime

So I finally got around to fixing the seat belt chime problem on my X3.

A few weeks ago, I had my indy BMW shop program my 2006 X3 to disable the seat belt chime and to turn off the chime when it gets below 37 degrees. Unfortunately, the programming does not work on US spec cars--despite the fact that the Autologic displayed the chime as disabled. Blah.

So here's my DIY on removing the seat belt chime...

Step 1:
Remove instrument cluster. 2 Philips head screws holding it in. Remove screws, then pull out cluster and disconnect cable harness.

Step 2:
Remove back of instrument cluster. There are 4-5 tiny torx heads screws holding the back of the cluster together. Remove them, then gently pry the rear of the cluster off with a small flat head screwdriver.

Step 3:
Remove speaker. With the back off of the cluster, I turned the car on, found the source of the noise, and err solved the issue. There is a small speaker held on by 2 solder points. Gently sway the speaker back and forth until the connections sever.

Step 4:
Reassemble cluster.

That's it... We read the cluster with the Autologic for faults, and it came up clean... The whole project took about 15 minutes to complete, and I am much happier without the ear-piercing beep every time I throw my laptop bag on the passenger seat...
