Recently had to remove the passenger rear plastics to gain access to the rear drip tray drain hose as some of you may know. During removal, I uncoupled the tweeter in the rear panel at the connector block vs. removing the whole tweeter unit from the trim itself.

I went to reassemble it all the other day and I thought I would test the speakers before refitting as I didn’t want the hassle of having to remove the trim again.

I reconnected the tweeter unit and left it sat in the cubby hole and fired up the radio.

No sound from the tweeter! - I’m pretty sure it was working before removal and has been stored safely so damage is unlikely.

Is there any reason why it ain’t working now?

I read the post below on a different thread which could indicate a problem - I don’t know if uncoupling the tweeter has somehow made it unrecognised but I’m a bit stumped 🤔

(I should note that all other 11 speakers appear to be working correctly, just not the one I disconnected at the plug.

What's weird with the Bose system is the amplifier knows when a speaker was disconnected while the radio is off. There are only 2 wires going to the speaker.
Do I have to reset the amp or something? 🤔

Possibly there could be a stored fault in the amp (address 47). This should be able to be reset via VCDS.

It sounds to me, that the amp carries out a confidence/handshake check through the Can Bus network, found your tweeter disconnected/not working, so the system had 'locked' the tweeter out until reset, I surmise.

That’s all I need. No VCDS and no one near me who wouldn’t charge me an arm and a leg to get a bloody tweeter working again just because it was disconnected at the connector plug.

Bloody great design this Bose system……

@ Steviejonees133 - You might want to double check the connection. If there's a sound system fault code, you'd need an OBDII device like VCDS or OBDeleven to find out what's reported and clear it. FYI - Fault code: 00876 - Tweeter, rear left-R14

OMG, are you guys serious? - I need to search for fault codes just because I disconnected a speaker at its connector plug? ……. That’s absurd!! I’ve never EVER heard that disconnecting a speaker would cause any kind of fault code……

What the hell is it with these cars? - why is everything so complicated :(

Doesn't need to be VCDS, just someone with a decent diagnostic equipment. To be fair all modern cars systems will be can bus or similar, nothing to do with Bose more like VAG/Bosch design, but I feel you grief 😢😢.

Just checked Halfrauds site, unfortunately they state this particular unit will only clear engine management faults/issues.

It doesn't help you but I have OBDEleven which I can recommend if you need to look at purchasing something for the future. It's handy piece of equipment to keep in the car. There maybe someone on the forum who's near your, who would be willing to help....

I have one with an iPhone and it works, get a 2nd gen would be my advice. There maybe a secondhand one on Fleabay.

My thoughts exactly, please bring back MK1/2 escorts, oops I'm showing my age.

Have a look at this, this should be good for clearing faults OBD Eleven You don't need a subscription unless you want to start coding new feature etc to the car, I think.

That looks good to me, if I wanted to start adaptations etc, I’d have to go pro with a subscription but otherwise it’s the same unit, right?

@ Steviejones133 - I have both the Ross Tech VCDS and the OBDeleven. As a casual user, the OBDeleven is probably the best way to go. Having said that, as a Roadster owner, you'll need the VCDS if you run into problems with the top and need to run the Adaptation for the Roof Flap Servos. The OBDeleven doesn't have this feature. Which is why I highly recommend doing the R&R on the servos sooner than later. The OBDeleven is perfect for checking and clearing faults codes and works on both Android and iOS platforms. If you haven't read it already, this post discusses the most commonly used OBD devices used in this Forum.

I've used the OBDeleven on both my Roadster and the wife's diesel Tiguan. The Tig had an engine light a few months ago, so I pulled over, plugged in the OBDeleven and found a fault code for a bad glow plug. Drove it straight to a local shop, showed them what was wrong and had all four glow plugs replaced. Job done!

The beauty of these devices is you can go in forearmed when you talk to a mechanic which significantly reduces the chances of getting pulled over the table.

Thanks SJP. So, even if I “upgraded” to the pro OBDEleven, it wouldn’t run a roof adaptation? - I’ve already bookmarked the servo R&R as very occasionally I’ve noticed a “roof not secure” light on the dash even thought it’s fully closed - as of now, opening fully and closing gets rid of it……oh the joy of owning an Audi
