    Audi A8 D3 fault codes. Repairs ideas.

    Hello all,

    I have recently bought an A8 d3 2005 (UK) year, and have been experiencing issues with the MMI, it is currently stuck up and blank. Boot screen will load then it shuts down. I have intermittent success by removing the battery, charging and reinstalling. This has worked to return the MMI to operational order a couple of times. But it is not solving the problem, so I have had someone perform a VCDS scan on the full system and the Optical bus.
    There appears to be an issue with the battery regulation management system and some of the MMI components.
    The dealer I bought the car from (non specialist) has offered to repair the car and I would welcome anyone's thoughts on what a repair/component strategy might be.

    From my own research I am thinking, replace battery, battery management module, boss amp.

    Full VCDS scan results:

    First thing I would do is check voltage supply to the amp.

    How old is the battery?

    -Uwe-
    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Battery is 2 years old. From the looks of the history that came with the car, it has had a new battery every 2 years since 2013.
    I have had the battery tested at 3 auto shops, with the battery on the car. Two readers displayed a 'excessive noise' message and didn't give any useful data. The third, gave a reading of 'battey unserviceable', 100% charged and 60% capacity.
    When I have had the battery in charge overnight, my charger says 'full' and I measure 12.8volts at the battery after charging.

    I tried a brand new battery on the car today at the shop and the MMI remained the same.

    I cannot figure out if the majority of the faults are battery/power management related or component failure.

    Can I check the voltage going to the amp using a multimeter? How?

    Thanks

    A new battery every two years seems excessive. Given that this car has almost 150,000 miles on it, it's not like it was only driven around the block.

    I wonder if the Battery Manager was ever told that the battery has been replaced?

    Have you tried the Battery History function available in our current Beta version? Take a look here:
    http://www.ross-tech.com/vcds/download/beta/17-5.php

    Sure you can check the voltage to the amp using a multi-meter. Wiring diagrams will tell you which pins should have power. The following threads may be useful:

    Thanks for the reply.

    I don't have the VCDS software, I paid to have a scan done so I can't check the battey history.

    Thanks for the links, I'm away from the car for a few days but will check at the weekend.

    I opened the car this morning and as I was putting bags in the boot (trunk) the MMI screen stowed itself away, having been up and blank previously. I started the car and turned the MMI on, I got maybe 20 seconds of music playing via CD then it all went blank and non responsive again.

    Do you think I have multiple issues here? (Amp, access system, battery manager, battery). Or could all these faults be traced to a single source of failure?
    The used car dealer I bought it from has offered to repair the car, but I know they are not VAG specialists so I'm trying to get the diagnosis myself so i know what needs to be done.

    Thanks

    Well, if you're going to own a 12 year old A8, I'm going to suggest that getting VCDS yourself would probably be a good investment.

    I think there are multiple issues here. If it were me, I'd work on the most obvious one first, and that's the MMI. Trouble with these cars is that when some things don't communicate, other things may not properly go to sleep, and then your battery gets drained..

    If they are not VAG specialists, I'm not sure they're qualified to work on this car. The systems in a D3 A8 are rather more complex than those in a typical Golf or Skoda.

    Yes, I agree that a VCDS is a much needed investment and it's on my list.

    I am more inclined to carry out the repairs myself as I believe that with the research I am doing I will be better equipped to do so.
    I do need to agree this with the dealer first.

    What are your thoughts on the battery management unit scan results? Does it need to be replaced?

    Thanks
