508 head up display problem

hello my car 2011 allurepaket I bought a second hand bought the head I could not get up, it was not working up, we went to the service, connected to the computer and opened it.

I had the same problem, we solved the problem by removing the front panel and moving the gears that enable the head up display to open 7-8 turns back and forth

Thanks, but I do not want to infect him at all recently. In the industrial industry, the screen has opened the man. Since then, there is no obstruction, sometimes it does not turn on.

Hello Who did you solve this problem? If I ask for information, my 508 sw tool has the same problem. Thank you very much.
