Weird electrical issues - 2015 E63
2 days ago my 2015 E63, the 360 cameras stopped working. Screens were just black but no errors. They work sometimes but 8/10 times, they do not work.
Then yesterday, I was driving slowly through town and the engine felt lumpy and I got a CEL. I pulled over and luckily had my code reader in the car so I scanned the codes and had 2 codes. "Misfire on cyl 6" and "cyl 6 ignition coil open fault. P0356".
I cleared the codes and it has ran fine ever since. Nice and smooth and no errors and I have done about 20 miles since then. Cameras are still not working though.
Any advice? My only plan at the moment is new coils and plugs. Should be arriving next week so hopefully no harm being done in the meantime.

I had issues with my cam too the solution was
replacement my aux battery. This was totally by accident. I notice my brake HOLD stop working being cold out ( NYC) I said that can wait.. I ordered new AUX battery and once I swapped my brake HOLD started to work and so did my cam. I would have like to verified this by reinstalling the old battery but you know.. So not 100% sure but maybe related to AUX

Update: Went to start the car and it is misfiring again. Checked codes, same codes, cleared them but the problem stays now.
Seems like I shouldn't drive anywhere. Now just got to wait for new coils and plugs to arrive.
Aux battery may explain the cams but my brake hold function works fine. I will do a resting voltage check tomorrow and see how it looks.

When I had a fault with my reverse camera I found that I had some moisture that had got into the connector on the underside of the boot (S212 wagon) and one of the pins had corroded and stuck in the connector block and snapped off, I linked the wiring straight through and replaced the fuse for the camera in the boot and all has been working fine since. It would definitely be worth checking the fuse, Mine was in the boot fuse box from what I remember. It seems that this is probably a separate issue to the misfire and hopefully the plugs and coils sort that.

Update:
I am still waiting for 8 Beru coils from Germany so I bought a random branded one off ebay to get me going and it is working fine. Still not changed plugs so it was definitely the coil.
My rev/360 cams are all working now every time. It seems letting the car sit for a week may have solved that issue somehow? I need to check under the boot next time it is up on a ramp to see if maybe there is a dodgy connection.
