Parking / side lights indicator light

I don't know about the solid indicator but my 3 Series passed an MOT in September with the amber bulb error on the dash. It was one of the tail-lights on the boot lid but the one in the light cluster in the rear wing was working and you only need one!

Well the error on the dash was concerning me most about the mot and you have confirmed what I read which is that the dash must correctly display the information ( that you are signalling a turn, have your lights on etc) I read that the likes of tpms errors are acceptable.
Cheers

So the plot thickens.
My sonar headlights apparently used to have an eyebrow which was powered on the same source as the angel eyes wired to the sidelight switch. Mine have wires cut. So allegedly when the eyebrow is connected these lights would be error free but lots of people didn’t like the eyebrow strip so removed them.
I am contemplating wiring this back up and adding a w5w 501 lamp back into the light or alternatively I have found w5w load resistors to try.
In the meantime I have put the bumper back on so I can drive the car for a while so it may be some time before I test this.
Chris D - if yours are the same you could try, or have a good look at the top of the cluster as this bulb may be your culprit.

My headlights are stock xenons fella.
I'm pretty sure it was due to the dodgy Chung Fang Dung LED sidelights I had in there causing the issue.
Replacing the old original halogens didn't resolve it so I'm going to throw in some new halogen sidelights this weekend while I swap in the winter wheels if I have time and see if that fixes it.
It's no biggie, as like yours the indicator solid stops when I use the headlights.

Any LEDs without resistors ("CANBUS compatible" just means they have them and about 4 W of heat to dissipate too...) will do it. If you want to used LEDs just code out the checks

I've had OSRAM and Philips for at least 7 years with no dramas, I'm sure filaments would have needed swapping out at least once by now.
