A8 mmi issue..

Hi Guys (and gals!)
Got an A8 with a bus problem where the whole infotainment network is down, done some reads of the car and on the forums, told to chance the controller mmi panel, which I did, but hasn’t fixed it. I have noticed that the fuse for the phone keeps blowing even when the module is disconnected and I run an optical bus check.
Can I

A: put an optical loop in so I can get the network running and then code the phone off
Or
B: get one of you wiz’s to help me fix it…

I'm not a whizz but I would use the optical loop down by the phone bluetooth module under the passenger carpet. You may have a damged cable somewhere.

So, your saying that the A8, not only has the module under the arm rest, which has the audi phone in it, but also has a bluetooth module under the passenger carpet? is this front or rear? do you know where I can buy a optical loop bypass from if this is the case?

Thanks

Sorry for the late reply as i've not been on for a while.
I'm not sure about the phone module under the arm rest. I have taken my phone cradle out as it is pointless if you have bluetooth and I'm not sure if there is a seperate module there. My phone and bluetooth was working fine then I disconected the phone just to use blutooth all good for 6 months or so. It stopped working (errormessage phone not connected) so I bought a bluetooth module. i took out the old one without replacing the new one right away and it stopped the mmi from working because it brokle the optical ring network. Plugged the broken blutooth module back in and MMI worked again. So I would buy the bypass loop (ebay they're not expensive) and place it on various places on the optical ring where modules are to see which one it is. If there is one under the arm rest I would start there then the blutooth one under the carpet.
Also have you tried posting in Audiworld.com? the a8 forum is a little busier than here
