MMI Motor Problem

[manca]

Hi All, three months into A8 ownership and the costs are mounting up...

At the weekend my MMI screen refused to raise when starting the car. I pressed the button to manually open it and it made a half hearted appearance stopping about a third of the way out of the dash. I pressed again and it retracted fully as normal. Next press up it came to its full position, but it didn't want to stop there and the motor continued to presumably spinning the cogs for a further 3 or 4 seconds before it stopped.

This has continued ever since, it opens fully but wants to 'keep going' for a few seconds causing a loud ticking noise and the screen to 'wobble' as I presume the cogs are still being driven. Everything is then fine and when I finally switch off the screen retracts normally.

A local specialist has told me I need a new motor. They believe Audi will only sell a whole new unit (including screen). Has anyone else had similar issues and/or found a solution If I can get a motor they are happy to fit it.

Thanks in advance for any advice
