Hi
This Q7 came to me with the MMI system completely dead!
Once I found what was causing the non power up of the system, the system started to work, but the controller in the centre console did not...

Hi, I test the system with optical loop cable. I tried connecting different. Systems installed at in the boot (Sat Nav, sound amp, etc) and under dash with female plug in loop cable, but still RMC MMI unit didn’t turn on.
I tied to put male optical loop cable in RMC control unit, to see if the systems cones in, but still no luck. But I narrowed down the issue to RMC control unit, I think the circuit board is faulty. Any help , how to replace or repair the RMC MMI board on Audi A1 2012? Thanks.,
The dude just dismantled the whole car like hell no I’m not attempting to do any of that. As an ordinary person with basic understanding of things, I thought the video would show an easy solution like pushing a hard reset button hidden somewhere in the car. Now a visit to the mechanic is inevitable lol
No magic buttons for when you decide to water the electronics of the car...
LoL
Thank you for watching!
@@LMAutoRepairs You're welcome. I wanna thank you as well. Very insightful video. I have the same problem with my 2010 Q7. I read somewhere that if you press Setup + the cursor and the top right arrow at the same time, the MMI would reset. Is that true? I tried it but it didn't work. You're probably right though. My wife (not me of course) probably spilled something there though there's no way she'll ever admit that lol
No worries...
I am sure there is a reset procedure...
All depends on your model...
👍👍👍
Hello
could you please tell me where connector Chestnut than you have tested number 20 goes because I don't have 12V on the radio or the center console.
for information all
fuses ok
optics is ok
My 12 V cigarette lighters work just fine, and my cd player lights up but mmi doesn’t work, it stopped working with the original circuit board so I got a replacement and it doesn’t work again. Also my screen turns on and off
H is my centre button doesn’t work when I scroll few lights are off I want to replace the board but do I need a 2g or 3g board ? It’s 2008 il has the navigation and a can conect my phone for calls
Nice one mate, always a wow when watching your videos keep it up.
Hi
Thank you for watching and for your comment!
👍👍👍
The Audi a6 c6 central panel half the keys work half it doesn't work and doesn't light up. The steering commands don't work at all and the lights, what could be a malfunction? And is the central panel of the mmi connected to the steering wheel?
I have no power on the mmi panel near the shift gear nor cigarett lighter. Also my mmi screen comes on with audi emblem and then goes out.
I dont have a fuse on my radio, maybe u know where it can be?
Thanx Louis, it always a pleasure watching your videos !!
Thanks Colin!
👍👍👍
That's a stupid place to put the fuse which powers the Cd player, the controller and the MMI. It should be with all the other fuses in a fuse box. This forces you to pull out the cd player which created a bigger headache
Meron akong inaayos na audi a8 2011 model loss com ang mmi pero kumpleto naman ang supply nag check na ako ng fiber optic ok naman .. pagkinabit ko sa iba ang mmi module gumagana.. ano pa kayang pweding posible na sira at dapat i check..
I have the same issue with my 2008 Q7, are you able to sort it for me please?
The plastics are very clean
Hi
Car.Audi Q7 2008 3000 TDI
İ will change odometer
Which path should I follow?
Sade mode
Hi, I’m having the same problem but with a Audi a1 my radio docent have a fuse on the back of it any advice
same here, did you figure this out?
What is number 18 for does that heat the car up before you go into it the auxiliary parking heating
There is no fuse behind the radio of my 2009 audi q7.
Wich is the fuse for the mmi?
i have the same problem but when i press combination of 3 buttons for reset everything turn on display and radio are working fine then when i turn off my car after minute car goes to sleep i put key in start the car radio and display is dead again when i press that combination of 3 buttons again it start again everything is working ???? did you ever had that case ?
No... never had that...
Hi i have audi q7 2011 the steering up and down not working what should i do only forward and back working any help thanks
I would start by get it scanned, and look at some live data... see if the issue is the switch or the motor...
Thank you for watching!
I have the same problem...but i can't find the fuse behind of radio!!! Where can be??
You might have a different model...
Check all fuses on the car... specially the ones on the interior fuse boxes... other than that, you might need diagrams...
Hi mate I've got a 2012 a6 and my mmi works fine but after 10 secs it switches off n the lights on the buttons stay it's like it get initial power n then looses it?
Hi
scan the car first... systems nowadays are quite smart, and they log faults...
See if there is anything that guides you in the right direction...
Thank you for watching!
my stupid mmi 2017 sq7 screen turns off while i'm driving and turning on like crazy
Hi friend can you explain audi A6 the same problem thank you
I have a a5 sometimes it boots up most of the time not but can still enter a CD and eject no mmi sat nav or steering wheel controls if u try turn on u can hear it trying to boot up
The problem others have experienced with Autel scan tools is if the computer is not responding, the Autel skips it. Unlike OTC which will list the system with a no communication error.
That's correct... it assumes that the module is not fitted...
Thank you for watching!
What did you use to take the radio unit out? Pleaseee I have the same problem
i have the same problem with my audi q7 2008
Hi I have got Audi Q7 2008 same MMI can we update it to android or Apple car play with a new screen ?
Possibly... never researched such thing...
Thank you for watching!
Any idea about 2009 mmi screen and control button lights on centre console not working? I had water in both compartments in the boot from the roof, all fuses seem to be okay. Cheers
Check the areas where the water has been... check for corrosion etc...
👍👍👍
@@LMAutoRepairs I've dried out everything, checked fuses again but unfortunately no luck.
Hello Good Morning. Where are you located?
Great work, and a nice find. When you replaced the board on the other car you spoke of, did you have to reprogram it or can it be replaced with a secondhand unit?
No reprogramming required...
👍👍👍
Awesome work/video! Thank you many times over!
😊
👍👍👍
Hi, nice videos. Wondering , what’s your location? I wanted to bring in car for repairs if you near by. Control unit & display screen stopped working suddenly. Though head unit still takes in cd/DVD & ejects etc. I need help to sort out this issue, Plzz

Nice video... my cars mmi display is fine but cd paused itself and no sounds from mmi. I checked the amp with fibre optic loop still same. Please could you give me some suggestions
I would scan the car and go from there...

Hi! I have the same problem and after to install the new board everything works fine, except te center selector cylinder. You don’t have these problem?
No...
Check live data... confirm that the button is actually working...
I know is a new board, but you never know...

WELCOME TO THE MOST BUS WORLD.....TRY DEALING WITH IT ALMOST DAILY.....I ALWAYS END UP REPLACING THE 07 MODULE...BUT I AM CURIOUS TO SEE HOW U COME OVER COMPONENT PROTECTION THAT IS ACTIVE THE MINUTE U REPLACE A COMPONENT OF THE MOST BUS CIRCUIT......LET ME KNOW..
Never had to do one... but heard is not easy...
Thank you for watching!
@@LMAutoRepairs U ARE SURE CORRECT...NOT AN EASY FREAKING JOB.....15 MIN TO REPLACE AND 50 MIN TO PROGRAMM THIS SHIT.............I WAS CURIOUS WHERE U PICKED UP THE BOARD...LET ME KNOW IF U ARE OK WITH IT...
Hi. Great vid. I have an A6 C6. Battery died and the local mechanic tried jump starting it through the battery rather than at the points under the bonnet. He eventually got it going but MMI hasn’t worked since. It starts for a second but then shuts down. I replaced the control unit, checked all fuses, replaced the amplifier in the boot and checked the radio unit in the glove compartment. Still same problem. Any suggestions?
Have you scanned the system?
👍👍👍
@@LMAutoRepairs Yes. My Polish mechanic scanned it and said that it was the fibre optic system was showing a fault and it was most likely a component in the amplifier in the boot. Mine is a Harman Becker automotive system. I replaced it and still have the same issue. He also suggest it might be the cable got damaged but it was working fine before the battery went dead. ???
The most bus can be diagnosed using fibre optic loops, and if it is a cable, you can also easily diagnose it by checking the loops...
I also doubt that the jump starting would damage a cable...
Yo7 need to check all the modules in the most bus... one by one...
And one thing... avoid to jump start cars with loads of electronics... that is what happens...
👍👍👍
Thank you very much this video really help.

From eBay at the time, if recall correctly...

Hi and thanks for your video. I did (change mmi) everything like you explained but the radio still doing the same thing. I'm suspicious to fuse. Could you please help me found where the radio fuse are located please? Thanks and God bless you.
The fuse is behind the unit... on the unit itself...
Thank you watching!
@@LMAutoRepairs Hi I have the same problem with the screen, and my system does not have a fuse behind it.. Mine is a 2007 Audi Q7 UK model.. thanks
@@MsREDCIVIC Change the amplifier in the back, my car had the same problem.
J.A.C.P I have a quick question?
Where is that amplifier located? Do you have a part number? I have a 2007 Q7 Can you post a picture of it? I already changed the MMI card and I have power on the line that plugs into the MMI card so my best guess is the amplifier may be the problem. Thanks in advance looking forward to hearing from you!!
Dear Sir, i have water damage on my amp. At the fibre inlet area. Do you maybe have a BOSE amp schematic for me - Audi Q7.
No I don't... sorry...
Nice video. Good to see you managed to repair it. I have seen that brown plug in the control unit of the windows in the driver door of my passat. :-)
Lol

Can anyone tell me how to install a aftermarket radio in a q7 sline quattro 09 TDI i have the fibers optics to the unit 10.1" and can't get the power to the unit i just want to no how the power go to the unit that is all it is 3 wire that comes out of the q7 i can't find adapter to go to my unit 1 of the wire is brown one is green with white the next one is yellow i no that it is the power i don't no if the green is the ground wire and the Brown is the key can anyone help out please i want to use this unit in the q7
Hi mate, good video. I have an Audi A6 C6 that has a similar MMI controller but the one with 4 buttons only. The screen works fine and it responds to some steering wheel controls but the controller in the middle console doesn’t work at all! I have tried to clean with alcohol as well but no success. Should have at least lighten up but is dead. Do you think there is a blown fuse as well?
Possibly... but check power and grounds at the controller plug... if all there, then you have a bad controller...
Thank you for watching and for your comment!

Hi mate, I've had a problem with a fuzzy display. There's no problems with power etc, just the actual display screen is different colours and lines, sometimes it would return as normal, but is now constant, I'm suspecting water damage as the drain in engine bay was blocked up and footwells became flooded. Do you have any advice how to fix this, thanks. Great video
Hi
If you suffered from water intrusion, there is no silver bullets...
Start by inspect and clean if necessary all the connectors, etc... see where the water went to and clean...
👍👍👍
@@LMAutoRepairs Thanks for reply, do you know if there is a connector linked to mmi, under carpet in drivers footwell. I seem to recall this, that would maybe explain problem
is the fuse behind the cd exchange or the actual radio?
