De-Lensing BMW E36 Headlights … DIY

De-Lensing BMW E36 Headlights … DIY

 
I’ve seen many good looking BMW E36 cars and I always noticed that they have one thing in common. It’s the standard Bosch headlights, but for some reason, the headlights looked a little bit weird. These headlights were actually delensed.

The Bosch original headlights have lenses that will help move the light in the correct directions. Unfortunately, these make the headlights (and the car) look ugly.

I thought that de-lensing is a hard job to do and honestly, I was worried that the result isn’t worth it. After I read about it and found that the job is easy and totally reversible (which is a major point to me), I thought I would give it a try. This is what I did:

1. First, I had to remove the headlights so that I can work on them easily. To do that, I had to start by removing the corner lamps or signal lights. Simply, use a screwdriver to pry the clip that holds the signal light to the main headlight. Then slide it forward carefully.

2. After that, I removed the headlights. It’s an easily job. You can simply reverse what I’ve done in my previous Replacing BMW E36 Headlights post. Just keep in mind that there are 5 screws that hold the headlight. 3 at the top and 2 at the bottom. Remove the screws and slide the headlight forward a little bit so you can disconnect the sockets from the back of the headlight.

After that, remove the headlights completely and put them at a table so you can work on them safely.

3. On each headlight, there are 5 big plastic clips (3 on top and 2 on the bottom). With a flat-head screwdriver, unhook them CAREFULLY. As soon as you’re done, the front part of the headlight should come off.

4. Take a breath and enjoy checking out the reflectors at the back part of the headlight. When the lenses come off, the reflectors will be easier to see from the front of the car which is going to be a sweet look.

5. Notice that both lenses are held in by factory silicone. Using a blade, slice them off. Your lenses should now fall out quite easily. If they don’t, you can use a flat-head screwdriver to gently nudge it out. Be very, very careful!

IMPORTANT: you must keep those lenses (2 on each headlight) in a safe place in case you decide to go back to the old look.

6. Clean the insides of the headlight thoroughly. I sprayed window cleaner then used newspaper to wipe it clean. You may want to wipe the reflector for the low beam as well. I didn’t do that though because it was very clean.

7. Now, hook the front part of the headlight to the rear part carefully (without the lenses of course), and then, put everything back the way it was. Now, you have de-lensed your BMW E36 headlights… Congrats!

Replacing BMW E36 Headlights … DIY

 

Hello,

If you’ve seen my BMW E36 pictures before, you’d know that I have low quality Chinese headlights. When I bought the car, I knew these headlights are not the best (lighting-wise), but I kinda liked the way they looked and of course the angel eyes with blue circles added to that look. So, I thought that I can’t replace them easily while keeping the car looking as good as it looked back then.

With time, these headlights started to show the marks of age and since they’re made of plastic, they were deteriorating fast. A month or may be 2 ago when I showed you that BMW E36 Headlights Guide, I thought to myself that may be it’s time that I replace those old-dusty-looking headlights with some original ones that are made of glass (this was my top priority). Headlights can be of huge effect on whether the car looks nice or looks old. Since glass headlights are not affected by time (at least, they are better at that than plastic), I made up my mind to get those glass headlights.

Replacing the old headlights with the new stock ones was very easy. If you care to learn how to do it, the most important thing is to keep in mind that there are 5 screws that will hold a headlight in place in BMW E36 cars.

Take a look at this picture. 3 screws at the top and 2 at the sides (bottom).

Lucky me, I found that my old headlights were using only 2 of the top screws to hold the headlight and the two at the sides were missing. So, I removed the 2 screws and the old headlights came out right away.


There was one catch here which made me realize how lucky I am, otherwise, this replacement task would’ve become a nightmare. The guy who changed the old stock headlights with these one-piece headlights was smart enough not to cut the sockets that were designed to plug into the original stock headlights. Instead, he scratched the wires and used auxiliary wires to connect the headlight wires with the old one-piece headlights. So, this meant that in order to restore everything to its original shape, I had to remove those auxiliary wires and tape the scratched wires. After that, I’ll just plug the sockets into the stock headlights and I’m done.

That’s exactly what I did. Then, I put the headlight in the correct place and slide it there carefully.

Before each headlight sits perfectly in its position, I connected the sockets to the the headlight.

Installing the turn signals was very easy too. The signal light with its socket will fit into the new stock turn signals perfectly. I didn’t have to do anything in there. Just plug them and you’re good to go.

Notice that you’ll have to be extra careful when sliding the turn signals to the side of the headlight. Never ever try to force it into position. If you’ve installed everything correctly, the turn signals will slide in perfectly with small pushing power.

Next, I’ll post about delensing my headlights, but for now, I’ll leave you with these two pictures of the new stock headlights

BMW E36 Sunroof Problem

 
Hi Guys,

I’m having a problem with my BMW E36 Sunroof. It looks like my motor doesn’t recognize the position of the sunroof correctly. So, when I try to open the sunroof, it opens but doesn’t slide all the way to the back as it’s supposed to. Also, when I close it, it keeps moving until it’s closed, then, it continues and starts tilting the sunroof. So, it’s like it can’t tell that it has already reached to the stop point.

I did some research about this issue and it seems I’ll have to reset my sunroof motor position. I’ll show you that procedure (DIY) when I complete it. In the meantime, you can check out the problem with my sunroof below

BMW E36 Sensors Explained

 

Hi Guys,

I know this is one of the most confusing subjects about the BMW E36 cars. Too many sensors with complicated names. Hopefully, this list will help you figure out what the most common sensors in your cars are and what they actually do. Have fun O_o :-


Symbol Name Job Picture
CPS Crank Position Sensor Controls the timing of firing for the spark plugs. Crank Position Sensor
CMP Camshaft Position Sensor Controls the timing of injecting fuel. Camshaft Position Sensor
MAF Mass Air flow Sensor Reads the volume of air entering the engine intake. Mass Air flow Sensor
ICV Idle Control Value By controlling how much air is allowed to enter through the throttle plate, it controls the idle of the engine. In many cases where the BMW E36 is not idling perfectly, the Idle control valve is the reason behind this problem. Read about cleaning the ICV. Idle Control Value
IAT Air Intake Temp Sensor Measures incoming air temperature. If the air is cold (more dense), the engine will need more fuel. Air Intake Temp Sensor
O2 Oxygen Sensor (Precat, Postcat) Monitors the gas that’s coming out of exhaust and provides readings to the DME to help it mix air+fuel better. Oxygen Sensor
CTS Coolant Temp Sensor Measures temperature of the coolant. Coolant Temp Sensor
TPS Throttle Position Sensor Measures changes in the throttle position. Throttle Position Sensor

BMW E36 Headlights Guide

 
Hi Guys,

If you’ve seen my car before (here it is BMW E36 318is), you’d know that I’m using aftermarket headlights and although I think these headlights look great, there’s a huge problem with them that is becoming more and more annoying every day. The problem is the headlights plastic lenses. They started to look dirty and old and no matter how I tried to clean them (I’ve even tried to wax them), they’ll revert back to the ugly-old-looking headlights which is clearly started to annoy me very much.

I’ve decided that I should ultimately switch back to stock headlights, but the problem is that I don’t want to lose the angel eyes and the HIDs. So, I started digging to see what options I have and to make some comparisons between the different headlights + their options that are available at the moment. I may write about these soon.

While doing that, I found this great tutorial about BMW E36 headlights and HIDs. So, I thought you guys (the BMW E36 owners) should watch this. It’s definitely helpful although a little bit long… I won’t keep you for so long, so, you go a head and watch it.
