Once I remove the three cables as you did, you left them not connected and only plugged in the MMI part only leaving the others hang loose?

[@toddbecker5730]

I have watched many videos from you! The way you explain everything is so great! Your efforts have given me the confidence to work on my 2006 A6 (C6). I've done a brake job (rotors & pads all around), changed O-rings on the variable timing solenoids (which stopped a massive oil leak the previous owner hadn't addressed), that led me to have a go at detailing the engine bay last weekend. Also, the MMI has been giving me issue ever since I took ownership two years ago. I've replaced the battery (under warranty) at least 4 or 5 times, thinking that the battery was faulty after the drain from the bad MMI. It was the Sirius radio transmitter that was bad! I bought a $10 fiber optic loop off amazon and swapped it out last weekend, came right back on just like your video! thanks so much brother! Keep your 2005 going and the videos coming! Thank you so much!

You save me so much time. I was about to call the company and say they sent me the wrong connector for the Bluetooth module before I saw your talking about the cover being on it and then I realized that that must be the case. So thank you. You save me probably a week's time and I will see if the repair works. Thanks awesome content, much appreciated

I’ve been driving without my MMI for over a year now and I just performed this exact job on my car verbatim from your video. Sure enough my MMI is operating normal again (without Sirius Radio of course) Thank you so much for all of these detailed and incredibly informative videos. If there isn’t something I can fix myself, your videos at minimum help me diagnose my car properly and allow me to provide a mechanic/technician with much better insight.

[@RomanTrollanski]

5:32 yes you are right,. That`s the XM radio, my car came without and without navigation as well, I ended up buying a used DVD Nav. for around $40 USD and used the XM Radio link cable to connect it to the antenna since it had one there already, I didn't have the XM Radio module anyway, and I didn`t want to purchase a "fakra cable" and run it trough since it had one there but wasn't used anyway... I ended up not using the navigation either, Waze can't beat yet by anything. But in the end, I purchase an MP3 Module ($140 at that time, in 2018), I place it in the glove box, upper wall compartment and I am able to play music from a Micro SD card or via Bluetooth from my phone, but I prefer from Micro SD card since it plays at 320kb like CD quality. Works with MMI interface, it displays songs on the LCD you can play/pause from the MMI console buttons which is just great!

[@Kinetic-Energy117]

Great video ty! I wish I could see a video of how to bypass all of the MM1 ring options

Hello there I have a question so the middle bottom and knobes aren’t working anymore

[@ThatAfricanGuy]

That happened to me too. I let somebody use the car for a while. When I took the car back, the middle MMI knob was not working well. He probably did not know how to use it and tried to tilt it. When I removed the knob, it was broken. I replaced it with another one and it fixed the problem. Try removing the knob to inspect it. To remove it, pull it up. It has a sort of spring and a plastic ring under it. If the plastic ring is broken, you have to replace to knob. To install a new one, just push it in.

Very good content keep it up. I have a question about the same car. The CD/Radio sound cuts out every 20 seconds or so for about 10 seconds then the sound comes back normal. What causes that to happen? Thanks a lot.

[@ThatAfricanGuy]

If you replaced the CD player with a used one taken off another car, the car will reject it. To make the car accept it, you should have component protection reset on the CD player at an Audi dealership. I believe component protection is to prevent theft. Some other electronic parts also have component protection.

[@yassergf1904]

@@ThatAfricanGuy No it is the original that came with the car. FM and CD both cuts out the sound then comes back normal. Not sure if the MMI module broken or not. Thanks a lot for the help

[@ThatAfricanGuy]

If the CD player was not replaced, inserting the key and turning on the ignition is enough to fix the intermittent sound disruption 😉

[@ThatAfricanGuy]

@@yassergf1904 If the MMI was having issues, you wouldn't have a working display. If you are sure nobody replaced your CD player without you knowing, and if inserting the key and turning on the ignition does not fix the problem, I would recommend disconnecting the CD player and reconnecting it to make sure it is well plugged in.

The screen stays on ok but works super slow and doesn't complete any tasks on any system. The radio switches in and out every 5 seconds. I bypassed the Sat Nav, Amp and FM radio units in the back with the fibre optic loop but its still not working. (I haven't looped the CD auto changer as it looks hard to get to in the glove box). It also makes the same quiet popping sound as yours did from the speakers but I don't have the Sirius sat radio unit. I had a slightly sticky button for years but it all worked fine. I removed the centre console to clean the button and took out the MMI board to check it, and it looked ok. I still got the popping sound even with the board out. Do you have any ideas. Thanks in Advance

Mine stopped today after i jump started my car and changed over the battery, what do i do?

[@ThatAfricanGuy]

How did you jump start the battery?

[@theholyoneofisrael.9550]

@@ThatAfricanGuy ive changed to a different battery now the centre conlsole and mmi unit is off, blank sat nav screen.

[@yizzysamathegreatest7034]

I just bought the loop fiber and I installed the fiber but my Mmi still won’t stay on

[@ThatAfricanGuy]

This means the malfunctioning module is not the Sirius. Plug the Sirius module back and try to bypass other modules shown on the MOST Ring in the video.

[@yizzysamathegreatest7034]

Idk where they are and how to remove them to do that

[@krazy2k334]

Hey bro, I really need your help. So I activated Sirius, to try to get it to work. Yet it still doesn’t work. What do you think I should do?

[@ThatAfricanGuy]

Hello bro! Just to get this clear, the MMI is working right? You just want to use the Sirius feature?

[@krazy2k334]

@@ThatAfricanGuy no brother, the whole thing is not working.

[@krazy2k334]

Same exact thing as yours.

[@krazy2k334]

You know how you said that they all connect to each other and if one thing isn’t connected it can cause it all to not work.

[@ThatAfricanGuy]

@@krazy2k334 Oh okay. The remedy is in the video. Did you watch it till the end?

[@gzimstyle9475]

What about the amp?

[@ThatAfricanGuy]

I'm not sure whether the amp is part of the loop to be honest.

[@yyz125]

That happened to me....but was the tuner

[@lii_Tyy5x]

Wym ?

[@jacobsolariechegaray4150]

The name of the ring?

[@ThatAfricanGuy]

M.O.S.T ring

[@ThatAfricanGuy]

I think I got your question wrong. If you are referring to the bypass device, it is called "fiber optic loopback connector". I purchased mine here: www.ebay.com/itm/322387179056 Here is the part number if you want to buy it from Audi or from another source: 4E0 973 802

[@enoal9242]

my radio doesn’t work radio is not installed

[@ThatAfricanGuy]

I apologize for the delay. If the CD Changer / Radio is not installed, the MMI will not work.

[@BOOOTNEYFUNZWORTH69]

Well done! I appreciate the feedback 👍🏾

@@rival3825 What did you unplug a few days ago?

[@FirstNameLastName-fu8ml]

Mine happened that for about 1 day because my battery died. The reason my battery died is because I leave my car for almost a month witgiyt driving. After two days of driving the mmi just fix itself

[@ThatAfricanGuy]

I am glad you are back on track!

[@AdanBarber84]

Is the plug male or female?

[@ThatAfricanGuy]

The connector that comes from the car is male and the loopback connector is female.

Watch this video about the MMI fix very well. It may help you fix yours.

[@squrl21mimi]

Yea I watch it twice but mines doesn’t come on at all even when I start it up ⬆️

[@ThatAfricanGuy]

Did you check whether you have the Sirius Satellite Radio Module at the back of the car?

[@squrl21mimi]

@@ThatAfricanGuy I didn’t look but I saw on your video in the beginning the mmi turn on twice and mines doesn’t come on at all

[@ThatAfricanGuy]

@@squrl21mimi Still, give it a try. That day I got lucky that's why it came on with the bad module.

My A6 got completely MMI DEAD never turned on again,. I checked fuse. ALL GOOD. vcds says: telephone/mediaPlayer/soundSyatem CANNOT BE REACHED. Also says: CanGateway 00384 optical databus 011 open circuit, ANY SOLUTION? Thanks

[@ThatAfricanGuy]

The way to troubleshoot this problem is to bypass devices in the MMI loop one by one. Bypassing the Sirius Satellite module fixed mine. Yours may be another device. I listed the possible devices in the video.

[@aknightwhosaysni2475]

I had same problem, so I grabbed a sledgehammer and smashed it up then set it on fire. 4 black alloys for sale if anyone interested

[@zilla4593]

Bruh saved you some money if you could remember to unplug it every time you’re not using your v.

[@dougsinden6881]

Sirius radio is only united States. And you're in Africa?

[@ThatAfricanGuy]

Correct. I purchased my car in the United States and I shipped it to my country in Africa because these Audi's are very very rare here.
