The flickering mmi screen is a well known issue. For me it's only visible in certain light. I think it's improved by setting the mmi screen to full brightness. It does seem like the mmi ambient light sensor is hunting between levels, almost seems like there is not enough detailed brightness level steps so the it appears to be flickering when its just changin brightness levels. Just my opinion.
I booked it into the dealer a few weeks ago with these 3 annoyances.
- Flickering mmi screen as described.
- Ambient temp display sometimes reads 0 degrees or lower when it's clearly a hot summers day. This seems to be getting more frequent.
- Radio logos don't display on mmi screen.
When I collected the car the next day, the service rep literally said "we'll done, you've found all of the issues that we are waiting for software updates to cure"
The car checked out fine with no faults when in the service bay.
He was able to show me other incident paperwork for the same faults. Just a case that they are waiting for software fixes.
Compete waste of time apart from getting the car cleaned! Oh and being able to test drive a brand new A6 for a day. Didn't like it, feels heavy and cumbersome compared to next gen A4 and seems dated inside in comparison.
Save yourself the time and effort, unless anything serious is wrong with the car then no point in booking it in under warranty.
He did say we will contact me when the software updates are avaliable, I dodnt hold out too much hope though.
