Hi all, I've changed my star to the light up emblem and connected it to the fuse box. Upon starting the car, there's an error message that says malfunction with a red battery symbol on the dashboard. Any help is appreciated.

I had a mid 70's Wolseley six that had an illuminated logo fixed to the centre of the front grille, great car, like riding around in your living room :)

Hi, Aqueel, I have exactly the same problem with my C350e/2016 for a couple of months now. drove to MB service two times, first time was told not the problem of battery, upgraded the software, second time told could be the problem of hybrid battery and waiting for confirmation from it.

they made that illegal in the end and they had to be disabled - pretty sure it still is to this day, I thought I came across it checking something about LEDs in construction and use regs.

I think it might be this (which would be pedantic) https://www.legislation.gov.uk/uksi/1989/1796/regulation/11/made
11.—(1) No vehicle shall be fitted with a lamp which is capable of showing a red light to the front
except– (b) a side marker lamp or a side retro reflector;

but had it been on the side rather than the centre it would be ok ???




FYI as a huge wind up for LEDaphobes !!! for NO good reason I can think of, the MOT failure for running nasty bright illegal bulbs on motorbikes has been lifted..... https://www.gov.uk/government/publications/special-notice-01-21-headlamp-conversions

I suppose you could say the same about illuminated door handles & sill plates. It was good enough for Wolseley ;)

I would disconnect it and see if message goes, if it does you know why.
Perhaps you would have been better off taking a feed from the side lights for it, or running a fused supply from the battery to a switch inside then back to the light, and switch it one when you wanted to.
