W204 C63 check rear lights, but all working?

[AL3X]

Again i'm back, another issue with my C63

I was travelling down the motorway today when randomly the nav/cd player etc shut off and the screen folded away, i tried to press the on button but nothing happened, after a couple of minutes I pressed it and it came back on.

But then just afterwards i got a message on the dash for literally every rear bulb(parking lamps, number plaste lamps, turn signal, bnrake lamps, etc both sides. theres 11 messages stored!

I have checked and all bulbs appear to be working, and the connector doesn't look melted or anything, so now i'm stumped.

The weird thing is the lad that was with me was adjusting his seat at the time, and now the lumbar adjustment appears to have stopped again, as I replaced a fuse for the other week. The seat movement all still works though so maybe just a coincidence?

I have checked all fuses already...please help i'm losing the will to live!

Sometimes a low battery can throw up a lot faults at once, might be worth checking

Battery seems to be fine I think...

An update, tonight I've messed about and noticed when I tried to use the lumbar support on the seats I could hear a relay clicking/humming from the rear fuse box, so I removed and replaced all relays, and now the bulb warnings have gone...the lumbar support however still isn't working!
