Question about 1994 BMW 5 Series

2 Answers

Headlamps too dim

The headlamps on my 1994 model BMW 540i (E34) don't shine brightly anymore. The 'brights' are great, but the regular beam is very dim. I have the correct bulbs fitted -- and SA laws prohibit fitting brighter bulbs than spec.

I suspect either that the glass has become dirty on the inside or that the inside reflective surfaces have tarnished / rusted (or both). I want to get inside it with a suitable polish etc. (Replacing the fitting is cost-prohibitive.)

Can anyone guide me to an online manual for dismantling and refitting the headlamps correctly? And any advice on the correct polishing / cleaning products?

In anticipation, many thanks!

Please check E34 Blogs, I have seen instructions to Remove projector headlamps, clean the reflector lens and re-install.

Good Luck, I sold my E34!!

Why are the high and low beams too high?

What is year--make--model? Are you saying the high and low beams are too bright? Maybe there is a dimmer control on the headlamp switch? Some vehicles have a dimmer for the headlamps and some don't.
I need more info.

No dims, just brights? Need lights or fuse? Is there more fuse boxes than the one under the hood?

Have you tried operating headlamps in manual mode, not automatic? Do they work correctly in manual mode?
You have a low beam fuse in under hood fuse box. With headlamps on, low beam, any voltage at that fuse circuit? Even if the fuse is good, if no voltage on fuse circuit, the circuit is still dead.
Any applicable trouble codes? Some of the national brand auto stores will check codes for free.
My info shows second fuse box under rear seat.

I have replaced the headlamps but dipped headlights still not working. What else could it be? fuse? Thanks, Euan

By "dipped" headlamps, do you mean the "low" beam headlamps? If so, the dimmer switch [located on the turn signal stalk] may be bad. Have you checked for power to the low beam wires at the headlamp electrical sockets? BMWs, unlike most cars, do have fuses for the headlamps, so yes, it is possible that those fuses have blown.

Hey there I've got a BMW 318is I've put new light globes in and had the nrma check fuses an still keep going out an stay out for a while, please help

Lights on these cars all run through an LKM box = light control module. It's purpose is to turn on a warning on the dash when some bulb is not working, and all models up to 1994 have terrible problems with failing headlamps, turn signals, brake lights, etc.due to poor solder joints in these modules. Very common for headlamps to fail driving down the road, or fail when changing from dim to bright. It is possible to repair by heating and re-soldering every connection in the box, but far easier to get one from a 1994 or later junk car, if you can find one.

Sounds like a gound problem to me. Check you headlamp grounds. The ground circuits for your headlamps actually go through the underhood fuse block, then to the headlamp switch, then through Splice Pack #SP203 (Located under the left side of the dash it is bolted to the left "A" pillar) , then to ground #G200. (Which is actually the bolt that is holding the splice pack.) I have seen corrosion in the splice packs several times. You may want to disassemble it and clean the terminals. A LIGHT coat of dielectric grease usually works pretty good to prevent it from doing it again.

Only brights work, dimly lit headlamps, no fog lamps

Recheck the bulb number. This happens when the wrong bulb number is installed. Otherwise it could be a bad headlight ground.

1994 ford f-150 with day time running lights headlightnot working

Daytime Running Lamps
The daytime running lamp (DRL) system is designed to turn the high beam headlamps on, with a reduced light output, and without illuminating the high beam indicator lamp in the instrument panel. You have a DRL Module.
The multifunction switch is the stalk on your column.

This is 96 F150 circuit. Don't have 94.
