Default Bluetooth Issues

Any suggestions on what to do about some bluetooth issues? For some reason, I cannot get the phone to connect back to the Q. It's an iPhone and has worked just fine in the past. For some reason now, it's not discovering and connecting properly. Any suggestions?

BTW, I don't need SA suggestions like "Don't use an iPhone" or "Is it turned on". I'm wondering if there is possibly a way to reset (I've already tried resetting the defaults in the MMI) or tell whether the BT system is messed up.

My wife & I use the iPhones and have not had issues, did you try to delete devices and reconnect it?

I had a similar problem a year ago and it turned out to be a faulty bluetooth module. Do other cells perform in the same ?

Si

Yes, I've tried deleting the devices. I'm going to schedule it for service. I suspect the BT module is bad, but I'll run a VCDS to see.

did you delete the pairings on both the Q and the phone?

VCDS will tell the tale if the module's busted.

I had problems with my iPhone as well and it turned out to be a bad part in the MMI system. I was surprised, because it had worked before. However once they replace the part, the quality of the sound on my calls was MUCH better.

Default Figured it out

Hooked up my VagCom and checked the adaptation. I noticed it was set to 0, not 1 (basically the module was off). I reset it to 1, saved the coding and it paired perfectly.

See here for the coding and adaptation settings:

Oddly enough. It turned off again. I'll have to hook up the Vagcom again to see if it really turned off. If it did, to the dealer it goes.

The Q7 went in today, so hopefully I'll have a resolution/solution to post if others have this problem.

Default UPDATE

The Q is back from the dealer. According to the dealer notes, they could not communicate with the phone module. They removed the left front seat to access the module, which "smelled burnt". The put in a new 4F0-910-336-HX interface, and now all is working. Obviously, some sort of short in the system.

All is well now.
