My car is 2014 C220 cdi w205 and I live in Croatia but the car is from Germany. The answer I got is it is possible to update headlights. After upgrading successfully, the headlights will turn on slowly when I unlock my car like this.

How to update headlights on C class W205, sedan?

Expensive method:

Just fyi those headlights go for about $1000 each…

Much cheaper method:

they do but can be had second hand much cheaper.

Also the dealer charges $1900 for light package so if you got your car for a good deal you can still come out ahead. I am pursuing an oem upgrade right now, and I can tell you it is not going to be difficult. It isnt plug and play, but it is fairly straight forward. If you have static LED it is even easier especially for USA version.

I havent 100% confirmed yet but due to USA headlight restrictions on the ILS system, the level sensors on front and rear may not even be needed. Just headlights, a few wires added to current connector, camera in windshield.

My car luckily came with windshield that had camera space built in. For some, they would need to change windshield to get auto brights feature. But they could still install ILS to get lights and look.

To install static LED headlights or ILS light? How to install?

the amount of work to upgrade is essentially the same. the only difference is front level sensor connection and camera in windshield. If you already have spot for camera in windshield then I would do ILS. if you don’t have spot in windshield for camera then static is fine.

buy harness from here

install rear level sensors and wires.
change headlight switch
install static headlights.
code IC, front sam, headlights, ignition module and they should work.
a lot of connections are same as ILS, so if you have windshield I would recommend doing ILS if you are already putting in all this work.

Follow one question: If you wanted to upgrade from static LED to ILS, you would just need the ILS headlamps along with the motor modules, correct? And then just plug the headlamps in and have the dealership code in the ILS…

The answer is: it depends where you are located.

for USA model, I am currently researching, but from what I have found, I don’t think US models use the level sensors. they just use the camera and other inputs from steering column. And their level is based on a prefixed setting that is user adjustable like many have mentioned in threads.

Essentially, you upgrade headlights and control modules on the head light. Run 1 extra sam wire per unit. Run extra power per unit and put in camera in windshield (may need new windhsield depending on car you have) and then code and you’d be done.

Another question: If you have halogen lights, is it possible to upgrade to LED?

it’s possible.
just takes a lot more work than static led to ILS. All new wiring. and need to code.

You simply cannot upgrade to static or ILS lights without coding:

Headlights no longer just take 12v and ground to work.

The ils and static led have control modules in them (microprocessors computers etc), thus everything is operated by the peripheral can bus network. Once power is distributed through the bus (2 ground and 1 power connector for static and 2 gorund and 2 power for ILS), the control modules light the led lights. The halogen lights are simply old school and run by putting power to them. There are dc to dc converters built in and all is handled at the headlight depending on can signal and front sam inputs.

You simply cannot upgrade to static or ILS lights without coding. I use the term coding loosely because the code is already there in your ecu and modules. You just must enable and disable certain strings. sometimes minor writing is needed, but for this you are adjusting lines of code to enable them to do what you want. All you need is a Star diag system sdconnece c4 or ecom with vediamo to do it.

Google and you will research there are a lot of tools online for sale for reasonable prices.

For me, www.obd2tool.com customer service is nice.

How to code?

the coding is something that a dealer can do.

but unless they can add to your vedoc to get code from Daimler, they must hard code through vediamo or dts monaco. they will most likely charge a pretty penny to do this. and keep in mind this is only if you install all the hardware. but if they cant get it in a reasonable amount of time or if you did something wrong, you will most likely get turned away and be out a lot of money.

if you are USA based, I have almost verified, that we do not use the level sensors for our headlights. so wiring is much easier. the kabel daviko harness is probably your best bet still but you will not need all the wires as he says.

I would buy a clone mb sdconnect c4 from obdexpress.co.uk and pay someone to code it. mhha auto has a lot of people on there and info. Once I do mine I’d be willing to help you out as well. but i haven’t done it yet so not ready to commit. but i have laid the road map out and its not too bad. the halogen to any of the led is much more involved.
