Question about Cars & Trucks
Hi, Thanks for reading my sade story I bought a 2007 Q7 about one year ago. Since the last 4 months problems with the MMI started. I am Angola (Africa), were we had a hot weather and dusk. - when I start my car the MMI display cuts out and dims as well and turn on the stereo and the sensor image for rear speed stop being displayed , after a few seconds the sound cuts out for a few second sometimes minutes, and then turns on again for a few seconds or minutes. I do not trust the dealer's diagnosis because initially he said to change the battery and the alternator; After doing that, the problem still. Then said maybe is the amplifier. I am looking for ideas from you all. Please chip in. Appreciate all your help.

first off, when it wont start check the voltage from the battery cable where it connects to the starter, if you have 12.5 volts there that will take battery cable corrosion out of the equation, then check to see if you have ground at the starter, which it sounds like you do not. it sounds like your ignition switch but hard to say from discription, make sure your battery cables are all tight, if you have all of this and its good i would say its the ignition switch which you can look up how to test in a chiltons or haynes manual from the auto parts store, if all of that stuff is good you can take the starter off and have it tested for free at autozone or any autoparts store, but usually the starter goes out really quick or just quits all together, if your not hearing a click noise when you turn it then your solinoid isnt engaging and means you dont have ground to it due to a short or bad ignition switch, that about covers the whole starting system, fuse isnt bad since it works sometimes. good luck hope that this helps you send me a message if you need more indepth help =)

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.

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:--
------------------- 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. .
