2016 A4 MMI turning off and on randomly

I need some repair advice here. My middle screen keeps turning off and on randomly while the digital driver display behind the steering wheel stays stable. Also, the buttons block doesn’t work when these issues happen. It seems to be particularly bad during heavy rain, so I suspect some circuit issue. Most of the time, there are no problems. Rebooting doesn’t help either. What could be causing this? The official dealer quoted 9k to replace a bunch of parts, but they didn’t even know what the exact reason could be, and I’m not ready to pay that much. Has anyone experienced anything similar?

That sounds frustrating. I had a similar issue with my car. It turned out to be a loose connection somewhere.

It could also be a software issue. Have you checked if there are any updates available for your MMI system?

I’ve heard that moisture can cause weird electrical issues in cars. You mentioned heavy rain; maybe some water is getting into the connections?

If you’re comfortable with it, you could try opening up the panel and checking the wiring yourself. Just be careful not to damage anything.

Did the dealer mention any specific parts they thought were causing the problem? Just wondering if they had any leads.
