Bluetooth & Audio Suddenly Out

Started my car after polishing and waxing, and received warning light saying "SOS Call Failure" (which then proceeded to disappear). My iPhone failed to sync with Bluetooth, and my iPod failed to load via AUX. Checked the Bluetooth display option and it showed OFF, but would not allow me to turn it back on. Checked Entertainment menu and FM/AM/WB/CD all showed available but emitted no sound when selected. AUX was not highlighted as an option.

The only thing that "changed" since my last start was I machine polished the roof of the car and hand-rubbed the Shark Fin. I also opened and closed the trunk several times to clean/polish the lid and fender edges.

About a year ago I had to splice about 7 broken wires in the trunk harness; some remained intact. Is it possible that the Bluetooth functionality and the AUX functionality are connected to the wire harness that runs through the trunk lid? Perhaps another wire or two have broken?

TIA for your suggestions as to where I should focus my attention to get these items working again.
Nick

It's very likely the bluetooth module since when that goes out it takes out audio too in a lot of cases. It all runs on a MOST loop and when one module goes down (typically bluetooth), it takes down everything with it. I've experienced this myself and the choices were a new BT module or just coding out bluetooth.

Theroux:

Many thanks for your response and guidance; I'd like to ask a few more questions.
Where do I find the BT module? Is it under the hood, in the dash, in the trunk?
Is it a simple DIY fix?

Thanks, Nick

It's in the front left of the trunk behind the carpet. You'll have to undo a few clips to get to it but you'll know it when you see it, it should be a big silver box bolted to the side with various wires coming out of it.

As for the fix, it depends. Some people have luck with just bypassing it with a MOST loop connector (which will effectively disable BT though) or you'll have to replace the unit and have the new one coded. Or the option I went with was coding out the module since the bypass didn't work for me, so it really does depend on the car and version of BT.

The fact that you can't turn on BT from the iDrive really points to the BT module failing since that was an issue I noticed when things started going that way.

UPDATE: Problem Solved

UPDATE:

I was driving this morning and hit a bump in the road, after which I heard a "chime" sound.
I looked over at my display and noticed that my phone was now paired to the car. Turned on the stereo/tuner and received a blast of sound from the CD player. Checked for the AUX port and it was there; selected it and my iPod loaded. So 100% back to normal now.

I have to conclude running the polisher on the roof near to the shark fin must have disturbed a connection somewhere. And the bump was strong enough to reconnect it.

Possibly but I wouldn't rule out the BT module possibility since a loose wire in the fin wouldn't disable BT. When my BT module was failing it would intermittently allow bluetooth to come back. I'm happy it's working for you now but if it goes out again, look at the BT module first.

Thanks, I'll try not to get overly excited at my good luck in case it goes out again.

Can you think of any other explanation as to what may have happened given the detailing work I had been doing?

Definitely seems like a module. I do not believe they require programming and can be found cheap on ebay.
