Try to reset it as per MMI manual.The reset procedure is as follows:--- press SETUP, BIG KNOB and top right soft button together.Make sure you press them simultaneously. When done right, the MMI screen will go blank, then show the MMI booting logo and return to the menu finally.Check fig below for which button to press:-- helpmech_42.jpg
------------------- This problem is also faced by many other users too.In there cases the MMI screen goes blank after car is parked in the sun for too long.The MMI starts working in their cases after the climate gets cold.So try this also.also try resetting by shutting car off, opening door closing door, and restarting the car--------------Check out this possibilities.This will help.Thanks.Helpmech. .

SOURCE: 06 A6 MMI radio switches on and off every few seconds. Bluetooth

Your most (fiber optic) system is inoperative. Its most likely your CD player and the bluetooth is an update issue, if it doesn't take the update then you need to replace your telephone transceiver.

I'm not sure if I have any good advice for you, but my 2007 Q7 4.2 is having the EXACT same MMI issues. Nothing works. The radio is stuck on one satellite channel and cuts out every second. No nav, no CD, not bluetooth. Audi is saying it is MY fault. That I spilled liquid on the instrument panel and dial. That DID not happen, so we are now in the "prove it" stage.

Hi, the problem you are having and the warning you are getting with the lights is telling us its saying device error, now this is caused by one of several problems, now the first problem you can try and solve yourself and the second you wont be able to do but ill explain anyway.
the first thing you should do is go to a computer hardware store and purchase a laser cleaning cd, now these cd's have loads of little brushes and when you play this into your cd player it spins round and cleans all the dust and grime off the laser and doing this may get it working again.

now the problem you are having relates to either a dirty laser eye, or the laser has moved to far up the track it runs on to read the cd and it may have got stuck or the last problem you could have is that the laser has reached the end of its life and may need replacing or adjusting of it has pots that can be adjusted.

anyway try the cleaning first then try putting a cd in and see if it will read it and remove the warning. how ever as your getting this warning its usually telling us either their is a cd stuck in the drive or the laser has stopped working or has jammed, if it was just down to a dirty laser it usually gives you a different warning, how ever cleaning it can solve the problem so try that first as you can do that yourself.

if the cleaning dont work by a can of compressed air from the computer hardware store and give it a good spray inside the slot for the cd and then try it, if it still dont work then this tells us either the laser has moved to far up the track it runs on or the laser itself has reached the end of its life and either needs replacing or adjusting if it has these pots that can be adjusted, how ever here is the problem, you cant but the lasers for these devices when they made them they never made them to be repaired they where made as throw away devices after their life has run out, this is a stupid idea as most can be repaired by replacing the laser or the circuit board that controls the laser so it is a huge waste having to throw these out so the chance of getting the laser replaced is very slim if not impossible.

the only plus side you may have is that some lasers can be adjusted using a multimeter and a screw drive but the problem is to do this the unit needs taking out and stripping down to get to the laser and even then not all lasers have these pots that can be adjusted to read the cd again, what happens is over time the laser gets weaker and weaker so you can usually tweak these pots if you know what your doing and you can bring the power back up and this can give you another 12 to 18months of use but without taking it out the car and stripping it down their is no way of knowing if it is adjustable or not.

the only real option you have is if the cleaning dont work is to get the unit replaced and either sell yours for spares or just scrap it, i know its a huge waste and most can be repaired if only you could by the parts but they never made extra parts so the only way of getting it repaired is to match a laser up out of another player or even by a damaged one and swap the laser over, this to would cost money to do as the new laser will need adjusting to work with the control board in your car.

i hope i have given you some ideas to be getting on with and im ever so sorry their is no easy fix or button to press to get it working again but if the cleaning dont solve the problem then the chances are replacing the unit as a whole would be a lot cheaper than paying sum 1 to replace the laser or adjust it for you and thats even if it can be adjusted.

let me know how you get on or if you need further assistance ok

Hi my MMI system on 2004 A6 asgone dead, no power


No solution, same problem, but had many strange moments: 4 months ago during 100 kms or so it stopped, then suddenly came back, and worked ever since. A few days ago, it started happening again: NAV stuck, then radio dead, and gradually the rest disappeared. I did a Reset, and since that moment I see the intro-screen and then it goes black. Hitting the TEL button is somehow also a Reset...

Do the previous 2 posters have anything to report on this matter? It would be VERY welcome!

Thanks,
Jeff
