I have owned a standard MY2006 A6 saloon for the past three years, which has been running perfectly, until it went in for an annual service. I have used the same independent garage for many years and have faith in their mechanics. The car is running factory fitted MMI High (colour SatNav screen) and that was working perfectly until the service.
Now the radio cuts in and out every three seconds - all the time.
If I press the DVD/CD button, the display shows I have discs loaded and tells me the player is 'Paused'. I can't access the CD player from the console and it won't play any of the discs, though I can load/unload CDs from the unit in the glove box.
The SatNav will display the map showing my location and tracks my progress, but I can't enter any destination.
If I select the phone option, the screen menu simply says 'Please wait..' which is not what it normally does. The car no longer acknowledges or links to my mobile phone via Bluetooth.
It is as if the whole MMI system is going through some sort of reset every three seconds (polling for a missing device?). The top element of the display between the speedo and tacho on the dashboard (which shows which radio station I am tuned to) flashes on and off in time to the radio cutting out.
The garage changed the pollen filter during the service, and I wondered if they had knocked/disconnected a cable when they had the glove box out doing that. The car has been back into the same garage and they have removed the glove box (again) to confirm that all cables are securely connected and nothing was damaged. They disconnected the battery for 10minutes and reconnected it again in an attempt to hard-reset everything, and that made no difference. I have reset MMI (press Setup/rotary button/top right button around the rotary button) and this has made no difference. All the modules in the boot appear OK - with no signs of moisture or loose connectors.
Are there any MMI experts out there who may have an idea where I go to next with this? I am pretty much resigned to taking the car into the local Audi dealer (Newbury, Berkshire) for their advice, but thought I should check here first in case anyone else has previously experienced anything like this and identified a fix.
I don't have access to any diagnostic tools, so can't provide any scanner data, and I appear to be miles from anyone with VCDS kit according to the map.
Thanks, Graham
