- In this video I discuss two additional fuse boxes that are located in drivers side panel and passengers side panel. The fuse box that's located in drivers side panel has no impact on the functioning of the MMI but the passengers side panel has MMI fuses that need to checked for issues if your MMI isn't turning on.

Thank you my friend i will check and tell you what my problem ben 🙌🏼🙌🏼
Feel free to reach out if you have any questions.
God Bless you, this video saved me time and money,
I’m glad it resolved your issue, thanks for watching.
Heloo man, i have audi a6 c6. I upgraded my front speakers, since than my battery gets drain overnight. I check fuses and mmi and i found out that my amp witch is factory amp is turned on when the car is off. Idk if it got something to do with speakers that i installed, im sure that i wired it correctly. Its been two months now i still didt fix than. Please if tou got any suggestions tell me ❤
I have a bose system in my 13 audi a8 3L. Bose amp has power but nothing going to sub or rca output off bose amp. I think the fuses are ok (back of rear passenger seat F 1 &2). What do you think the issue might be? I read somewhere the MMI software update could cause the subwoofer to shut down. Any ideas on this? Thanks in advance for your help!
I haven’t much exposure to the update causing issues with the amp, I have done updates myself in the past.
Variety of things can be causing this issue lack of power to the amp, the amp might have power but the voltage is not enough feed to the sub.
- Damage to the sub potentially
- faulty wires
- incorrect connection
Hope that’s helpful
I have a 2016 Audi q3 my mmi won’t turn on I’ve tried resetting it and it tuns on for a few seconds then blacks out again . I can’t use the radio either needing help don’t know if it’s a fuse. The box in the trunk or my mmi needing to be replaced
How did you solve the problem? Have the same problem in my A5
Hello, I have 13 Q7 mmi and sound, and the radio went out. The battery kept dying, and I came to find out the factory Amp was bad. I replaced it. everything works, but no sound is currently unavailable. What do you think should be my next move?
How you find out your amp was bad and did you solve your issue. I have same problem no sound but mmi works
My screen turns on and then off and I have to reset every once in a while to turn it on then shuts off again. Also, Fuse C4 in the right trunk compartment keeps blowing. I think this is for the amp? I disconnected all and have it drying. There was water inside the amp and radio bay which I will be fixing due to bad drain tubes. Any suggestions or advice?
Any type of water damage is not good near the amp. Depending on how bad it is drying it out isn’t always going to resolve the issue.
With everything being in a loop, if one module/fuse is not working everything stops working.
I would fix the leak and hopefully after the drying process that resolves the issue.
It seems like you haven’t done permanent damage to your amp from what you are saying.
I have the same problem can't get it off mute,
How did you disconnect it
I have an Audi A6 c6 2006, my audio only stopped working but MMI is fully functional, is the fuse for that? I don't have a Bose system just a standard one.
It may be the stereo amplifier they finally figured that my draw of battery was coming from the amp it shorted out by getting wet through the back panorama glass
@@DroHeadXx it randomly started working again, seems fine so far also it is all dry, been dry aswell
Hi, i have a 2013 q5 with b&o and my screen is black. It turns on and turns off something when i restart the car. Looked in the back and found that the 30amp for DCDC converter path 2, DSP
amplifier, radio was blown. When i try to replace it, it sparks and blows again. So far the only thing ive found to make it stop sparking is disconnecting the amplifier. What could be the problem?
Interesting scenario! It’s difficult to say. Did the amplifier ever had water contact ?
There are cases where the pipe for the rear window washed can leak into the amplifier.
Hi, I have audi a4 2008, my MMI is not working properly.. some time, it works for 1-2 hours and goes off. But screen is on most of the time just have an issue with audio. Any suggestions please
I’m thinking if it’s your amplifier but you mentioning it works intermittently something is causing the disconnect to happen.
Did you attempt to disconnect and reconnect amplifier that’s found in the trunk on the drivers.
Something else i would do is identify the fuse that’s responsible for audio take it out and inspect it. Inspect to see if the slot is dirty where the fuse is inserted.
I have a 09 q7 k haven’t checked fuzes yet but my mmi works the problem I’m having is the only speaker that works is the driver dash speaker all the others aren’t working. Anything you can think of? Thank you in advance.
You figure out the problem?
Same here but all of them work accept the rear speakers did you figure out the issue?
Hello , i have a6 c7 2012, when i start the car , my MMI doesn’t opened , when i force opened with button , the Mmi opened and showed Audi a6 Mmi screen and after few seconds goes down again ? All fuses i check its okay , what i need to do ? If someone have same problem please tell me
Several factors could contribute to the MMI closing after briefly displaying the Audi A6 MMI logo.
A temporary software glitch or bug in the MMI system could be causing the shutdown. Try a force restart the MMI.
Does the MMI screen open when you try to reverse?
@@homeoftheobsessed1168finally i found the problem ,
@@fitimzahiri8810 If you don’t mind sharing what was causing the issue?
@@homeoftheobsessed1168 yes bro it was the central radio , i can send the photo of piece what was the problem because the water was joined
@@fitimzahiri8810 that would be great, interested to see it.
my mmi was fully operable but after a new battery replacement it will turn on the loading screen then go completely black. and it repeats that cycle after pressing any button to wake the screen. it always ends up going black. how do i fix??
i should add it’s a 2009 audi s5
I have THE SAME issue with the same car 😫😫😫
@@jesusluna6397 so i fixed my problem, all i did was re-secure the battery ports back onto their respective socket. made sure it was extra tight and it worked for me. i’m lucky it was such an easy fix especially when i called a couple local shops they tried to charge $180 just for diagnostics
My radio works but the mmi display does not come on tested the power to it. It has no power to it but what fuse do I check, all the fuses in the boot are ok
It’s difficult to tell you what specific fuse to check since multiple fuses control variety of features of the MMI.
In the trunk area, the fuse box contains rows B thru E, the last row has 7,5 ampere rating if you want to check that.
Take it out and inspect it.
@@homeoftheobsessed1168 ok tomorrow I will check every fuse let you know want i find thanks
Right I checked today and yes a fuse was blow on the left panel inside the car. Mine is a right hand drive so not sure if its different on left hand drives. There are two fuses in the boot(trunk) radio and mmi both blown replaced them just had the radio working. Three fuses left hand side panel mmi, radio and cd. The cd one had blown all 5 amp rating when I replaced the cd one mmi works now. So I believe if any one of those fuses blow the mmi will not power up. But anyways all good now.
Glad you got it working again.The multiple fuse boxes definitely make it confusing.
I have audi a3 8V, the MMI screen doesnt rotate up neither the functions are working on the mmi panel
My Audi s5 the mmi turns on but radio is stuck on mute. Would that be the amp? Back up camera all that stuff works on the dash but the radio is muted and won’t unmute.
Did you ever figure this out?
My screen and sound when blank and mute and suggestions ?
hello, I was wondering if anyone could help me, I lent my son the car and the battery ran out, a friend of his went in his car and with the help of some clamps they tried to turn it on but they connected them inverted and from that moment the MMI and dvd, explorer lights do not turn on.
audi q5 2010
Depending of the severity of what happened after connecting the incorrect positive and negative clamps.
- battery could be destroyed and need to be replaced
- i would check to see if any of the MMI fuses have been blown. The main ones found in the passenger side.
I’m assuming you got the car running.
You could have also fried the ecu 🤦🏽♂️
My MMI turns on with white light only and I do not see anything on it - where it went wrong , any idea ?
Audi A6 2008 3.0 Quattro
Initially I would say you would need to replace the screen. How good is your battery? If the battery is bad, it enables the power management system it disables things like MMI/radio.
@@homeoftheobsessed1168 Battery is in warranty condition. I can get it checked or replaced. But the display used to flicker earlier and now it's only white screen however sometimes it comes back but flickers.
Did you ever get this fixed? It seems like it was gradual breakdown of the screen. Knowing that it seems like it wouldn’t be a battery issue.
@@homeoftheobsessed1168 i also have this issue atm, some times it works, sometimes white, sometimes grey, sometimes flickering
@@homeoftheobsessed1168 no , I have not yet get it fixed. It could be the screen breakdown issue as you have mentioned. Can it be an issue with amp ?
Hi I have Audi a4 2011 checked all the fuse the music system working but no sound coming sometimes it’s work but sometimes no sound any help ??
sam problem
is your fix sound?
My s4b8 mmi does not come only when weather it’s hot any idea please ??
You are saying that the MMI works only when it’s hot outside?
Have you done any modifications around the MMI screen like trim? Did you ever remove it?
@@homeoftheobsessed1168 it does not come on when the weather it’s hot. When the weather it’s cold it turns on anytime. And I have not done any modifications.
It seems like in B8 platform they had issues with the screen itself.
I believe some of kind temp monitor is malfunctioning that is equipped with the MMI. The only way to fix that is with a software fix. I would assume The Audi dealership would fix this issue because A service bulletin is available since it was wide issue with the B8 platform.
@@homeoftheobsessed1168 thank you so much I will contact the Audi dealership soon. Thank you !
You’re welcome! Hope everything goes well at the dealership.
Hi thank you for this video. My Mimi control, radio, volume are all gone. I can not access my mmi at all. I can not access the control panel!!
I have no audio, “no signal”. I can Not reset my tire temperature or any other function. Please help
It sounds you have no power going to the MMI at all.
1. Battery check - how old is the battery?
2. Did it suddenly stopping all at once or it did a function stop working at a time? The reasoning I’m asking is to identify the point of failure, potentially a fuse might have been tripped causing all functions to stop working.
@@homeoftheobsessed1168 it stopped working suddenly.
The battery is fairly in good condition.
One night out of nowhere, I lost signal to my MMI on the screen, no response from control buttons, no audio/radio etc… all at one
@@Tired_leopard it’s difficult Diagnose the issue when you don’t have a point of failure
1. Checking fuses, use multimeter to check each fuse and ensure that no fuses are burned out.
2.check amplifier check for water damage
3. Check the modules - going to make video on the process of checking those in the future.
4.sometimes the buttons malfunction and need to be cleaned.
I don’t have a straight forward answer. Hopefully you get it working again.
@@homeoftheobsessed1168 thank you so much. I’ll check them out soon and can’t wait for your new video!!
@@homeoftheobsessed1168 it was the fuse. I was able to fix it :) thank you dearly 🙏🏾
If anyone else loses all MMi control, sound, radio etc…. On Audi A4 2016, please check your passenger side fuse box-Brown box- change fuse #3 (ATC 5)
Help please 🙏 my mmi screen has gone blank. Volume went then seconds later the screen went blank? Tried all sorts, fuse(all good) hard reset (number of times) screen comes on then goes off after a couple of seconds and even disconnected the battery. I am lost for what to do next and advise? It’s frying my head now 😂
I’m surprised it’s not resolving the issue with the hard reset especially with all the fuses being intact and working.
If the sound went first, it could be the amplifier or HDD? Everything is in a loop, if the amplifier is fried than everything else would stop working.
Did you by any chance change your battery recently? Audi has all these safety measures if power isn’t being delivered, it shuts down battery draining features.
Temperature plays a role as well, just making sure your Audi hasn’t been outside with high temps today?
@@homeoftheobsessed1168 thanks for getting back to me much appreciated. It’s was Saturday it went down, and with you saying the outside temperature could have played a part all last week here in the uk it was hitting hight 20 degrees low 30 degrees it could well have been the issue. But as for the amplifier I wouldn’t know where to start with that.
Anyone know why my MMI box has a flashing blue light inside? Screen is black and it won’t connect to my phone. Tried everything!
A flashing blue light on your Audi MMI box typically indicates that it's in pairing mode, trying to establish a connection with a device. Since the screen is black and it won't connect to your phone. Have you tried restarting(force restart) the MMI system?
The 12 volt socket under the glove box blew a fuse when I was removing it, replaced fuse and 12 volt works, but it’s caused the black screen issue with the MMI box, and won’t recognize my phone. The MMI box must be getting power as the blue led is flashing
It sounds like there might have been an electrical surge or disruption when the
12-volt socket fuse blew, which could have affected the MMI screen functionality.
Try performing a hard reset on the MMI system by pressing and holding the control knob, the MENU button, and the top-right soft key simultaneously until the system reboots.
Disconnect the car's battery for a few minutes and then reconnect it. This can help resolve the issue but I wouldn’t recommend doing this(last resort)
@@homeoftheobsessed1168 you mean on the actual stereo. You mean the volume button and the mode button? Not sure what right soft key you mean
Press and hold the volume knob (or Drive controller) and the CD/DVD eject button simultaneously for about 20 seconds.
is there a fuse for my mmi
It doesn't have a single dedicated fuse, as it relies on multiple components and modules throughout the car if that’s what your asking.
My current problem is when I turn the car on, the screen pops up, nothing shows on the screen and then after a few seconds, it closes. The radio doesn’t work, can’t access anything through the screen. Buttons on the center console don’t light up either. Any help would be great
I have the same problem , if someone can help us with some information …
I have the exact problem too if anyone finds the fix let me know
Mee too
Same, mini literally turned off when I took it through the drive threw car wash lol
@jordanleaf2694
Did you get sorted? Mine did the same Saturday tried alsorts but still no joy
Not sure if anyone has this problem? I have an Audi A4 2018. Sometimes I have a black screen and sometimes my virtual cockpit and mmi goes very dim?
Most of these screens in Audi have auto dimming functionality - sensor is always evaluating how much light exposure is present and auto adjusting your screen.
Usually you can disable the auto dimming with Vagcom or dealership should assist with you as well.
Here because my 09 A4 mmi and radio and center control stack lights don't work :(
Didnt work for me too
You don’t have any power coming to the MMI?
I see in the dark that the screnn somtimes goes on but black no rs logo nothing 1 sec and it goes of this happening all 5 to 10 seconds the controll bottoms are all off
I called yesterday a audi garage im bringing the car to them tommorow i keep you updated what was wrong with my car
I’m interested to find out what the issue is.
Sounds like isn’t fuse issue since you checked that. It’s quite hard to figure out what the issue could be.
If you have done any electrical replacements in the car recently like battery change or module change. Usually requires dealer reprogramming.
Please let me know what you find out. Hope it’s quick resolution.
I didnt do a a change to the modul or battery the only thing i did i changed the trimm in the middel from alu to carbonfiber 4 month ago but until now it worked fine from one moment to the other after 4 month it stopt working
Onpas epäselvä ja hyödytön esitys
Ah, ah, ah..... Cocaine is a hell of a drug 🤦♂️
All we see is your scalp
Definitely need to improve my recording and just being on camera.
My screen, center console buttons and radio are all out of wack. 🫠 sometimes the screen will turn on for a few seconds, then it will shut off and not turn back on.
When it turns on or off, does the amount of lighting that comes through your car change? For example it’s sunny vs. afternoon when it’s darker outside.
@@homeoftheobsessed1168 🤔 I didn’t pay attention to that. I’ll have to check it out and see. I checked both driver and passenger side fuse boxes and everything checked out good as fuses go. Never checked the stuff in the trunk though.
@@phantom_heart2323
@@homeoftheobsessed1168 hello, hope everything is well. My MMI is completely out now. The screen does not turn on at all anymore. The speakers and red lights by the gear shift are all still out.
I have the same problem 😢
