Audi Q3 2014 - the MMI screen is dead, so I ordered a replacement second hand unit with the same part number as the screen removed. I've plugged the unit but still no display.
I've read various posts on the subject and I've tried the following:
1. Resetting the MMI - I think on this model it is the main centre button, menu plus the top right arrow together - the radio goes off and comes back on after releasing the buttons
2. Checked all fuses (in the cabin and under the bonnet)
3. Checked the cable that plugs into the screen as I read it can become worn due to the screen popping up and down - there isn't any noticeable signs of wear and tear
Of course I can't rule out having been sent a faulty replacement screen but before I return it are there any others things to check as I'm kind of out of ideas.
Thanks in advance.
