2018 E Class dash board lights going off
Hi all im new to MB world, im hoping someone can help me diagnose the problem with my W213, firstly from time to time the centre where the rev counter and speedometer are located goes blank also the back light for both gauges goes out for a second then comes back on displaying the seat belt warning, the other strange thing is when on DAB radio it starts off fine then the tune starts playing a bit slower than it should, we have verified this with another merc DAB parked next to mine.
its been back to mercedes twice now and im waiting for them to call me to get it booked in, i was hoping someone on here might know what i should look out for.
i hope someone can help any ideas are greatly appreciated.
