Hi!
I'm a new poster, but an old reader!

Like the title read my MMI has gone down... totally dead.
From one day to the other.

I've checked all fuses and they are good so far my eyes can see.
When I do a hard reset the unit In the glovebox (5f?) makes a Buzz but nothing else happens.

The other threads I've read everybody have seen the splashescreen for 3 sec but mine is totally dead.

It hasn't rain since last time it worked.

The car is a 2009 Avant c6
I have MMI 3g basic without nav.
I don't have access to VCDS but obdeleven.

Thanks in advance!!

Bypass the Sirius satellite radio module if you have one by replacing it with a this loopback fiber optic bridge: 4E0 973 802.

Read my comments in this thread for more info: https://www.audiworld.com/forums/a6-...blems-2963758/

Thanks for answer!!

Ok. But I'm not sure I have that module. I only have one module in the back left side and that's this 4F0 035 056 A.

Or am I wrong??

Rickard Olofsson

I did also see the aerial antenna amp 4F9 035 225 A in the back.
frogot to say that I can't reach the 5f module with the obdeleven.

And another thing I thought of was that I change breakpads back and open, closed and test cycle the parkingbreake...everything works fine but I couldn't reach the parking brake module either...don't know if this is related but...

Is the Arial antenna a part of the loop?

kelisko

No, not that one. The one I am referring to sits vertically and faces the left tailamp. It is smaller.

Here is its part number: 4E0 910 593 N

It looks like this:


I am not saying I am sure this is the cause in your case but it was what was causing my issues and the fiber bridge is cheap enough to go for it and give it a try. You will find it way cheaper on eBay.

kelisko

What do you mean by "you couldn't reach the parking brake module either"?

Rickard Olofsson

Ok. I can't find the one you referring to....I have a EU car so maybe I don't have satellite radio??
I just see those 2 modules in the left back.

Oh sorry...I might just use wrong words...in obd eleven there is a controll unit that reads "parking break"...the one I entered when I change breaks..after this happening I can't enter the unit anymore.

Thanks again for answers it sucks to drive without music....😟

I was really hoping it was the Sirius because the fix is cheap and easy.
However I have heard the bluetooth module can also fail and cause these issues.
Here is a thread that discusses that: https://www.audiworld.com/forums/q7-...odule-2860677/
There are also other threads around here about the MMI issues. Do some research and you should find more info.
Good luck...

Thanks alot....I will check around!!
