Have you tried this:
1 - Module 09 - Electronic. Code (31347)
2 - Adaptation
3 - Select - Control of intermittent
4 - Sub - Komfortblinken blinkzyklen
5 - Change to the desired value - Maximum 5
6 - On the car infotainment screen, reset factory settings for the lights section.
will give that ago, when you say reset is that the whole MIB system or just the lights section?
