Nothing works on my bmw I drive blank black screen flashes now and again
Unfortunately, you will need to replace your screen.
It might have started as sporadic flickering and that were early signs that the whole part was failing. Sorry about that my friend!
That is an indication that your CCC unit has failed. I have seen that happened many times. You can install a used CCC but it will need to be programeed.
You need to code 5 modules in order to have the CCC working completely:
In that order. Autologic should be able to do that but NCS Expert can definitely do that. Main dealer BMW software cannot code used modules, they can only do new stuff.
