Assuming you have a 1999 323i, check the following:
The only common factor is the light switch.
Remove the light switch, have it hanging out and still connected and measure the pins / wires as follows:
Position
0 = Off
1 = Park lights
2 = Park lights and Headlights
Right Hand Taillight
F37 (Engine Bay, 10A) feeds power on Red/Blue wire to pin 11 of the light switch
The switch switches power to the taillight.
The wire to the taillight is on the switch pin 2, and is Grey/Yellow.
If no Check Control fitted, the wire goes direct to the taillight.
If Check Control, it goes via the Check Control module and becomes Grey/Blue/Yellow for one bulb and Grey/Blue/Yellow for the other bulb. (maybe BMW made a mistake with wire colours here?)
Left Hand Taillight
F33 (Engine Bay, 10A) feeds power on Red/White wire to pin 5 of the light switch
The switch switches power to the taillight.
The wire to the taillight is on the switch pin 6, and is Grey/Violet.
If no Check Control fitted, the wire goes direct to the taillight.
If Check Control, it goes via the Check Control module and becomes Grey/Violet/Yellow for one bulb and Grey/Green/Yellow for the other bulb.
Instrument Lights
F37 (Engine Bay, 10A) feeds power on Red/Blue wire to pin 11 of the light switch
The switch switches power to the light dimmer.
The wire to the light dimmer is on the switch pin 1, and is Grey/Black.
This goes to pin 3 of the Light Dimmer
The power leaves the light dimmer on pin 2 and becomes Green/Red
The Green/Red wire then goes to all dash illumination including the instrument cluster, where it becomes pin 2 on the cluster connector.
CONCLUSION
If you have the right hand taillight fail at the same times as all dash illumination, then suspect F37 and/or the light switch.
Check the fuse carefully, the connectors are firmly seated and clean and tight, and the light switch
If the light switch has failled or has bad connections, replace it with a new one
Thanx for the help, Ive checked the fuses before but when I checked again today F37 was blown.

Hey guys Ive had problems with elecs before and Ive fixed it all today
until I realised that headlight brakelight turns off upon engine action.
Turning on the headlight and starting the car turns the headlight brake lights off,
and if I turn headlight off and turn it on again it works fine,
until I start accelerating the car. This is TOO weird,
wat does engine revving have to do with anything? any suggestions?
Ive suspected battery but the batt is brand new

Did you get around to solving this problem? I have the exact same problem in my e36Windows work now just the cluster lights and panel lights that are around the headunit

My e36 is having all sorts of elec problems.
The right tail light does not work properly most of the times (Sometimes fully operational) and only work sometimes because I have directly connected the left side to the right side (The headlight wires do not provide power). The left side works and the right side does not when theyre linked together which doesnt make any sense? The right park light does not work either, the bulb blew so replaced it with a new one but it doesnt like to go on. The dash lights have given up on me also...What could the problem be? My warrant money is only valid for a week now and this car is messing up my life. Any valid suggestions?

Can you sell the e36 front king springs super lows to me? If its for a six cylinder of course..i have a front set for e36, but i don't think they will fit.
WOF/OBC problems e36
in Electrical system
Posted · Report reply
Apparently there is a 'new regulation' for WOF and one of them is that you cant ignore the warning messages in the OBC. The right side did not have any power for brake lights so I cut that off and hooked it up to the left. The problem is solved but now the other problem is that OBC will throw messages at me forever. This dumb mechanic thinks chucking the factory ones will fix the problem but I know that is not the case. Is there a way to unhook the OBC (just the OBC not the clock) temporarily?
