- Mercedes-Benz E-Class: How to Replace headlights with HID
Guide to diagnose trouble and recommended solutions
HID, fog lights, headlight install guide 211 E series may work on other series models
I want to do on mine also but cautious about it. Did you have any errors on the comand system after you installed it? Where did you buy your HID fog light kit from? There are a tons of it on ebay and not sure which one is right for ours. They are all claimed to be. Thanks!!!
I'm really a novice to this so i'm not sure what they are called, but they seem to make adding the capacitor a lot easier if you accidentally put it in the wrong direction it seems those connectors can easily come off for you to correct it.

Finally, I got tired of having to diagnose which is which, so I bought a CANBUS ready kit (although 35W only), but it has been working fine since. I no linger get an error message nor do I get the on-off-on-off issue.
By the way, it was the same issue with my 08 BMW 5-series, it would not stop flashing until I replaced it with a CANBUS kit.
I hope this helps others who encounter this issue.
I am having a strange problem. I am using a 55W canbus HID kit for low beams. Before capacitors the left side did ignite approximately 5 seconds after right side and I also got error message on left side. This always happened during cold start, never on warm start.
After I soldered 4700 uF 35 V capacitors I never have any error message, but now the left side does not ignite at all on cold start. If I turn the lights off and on it will ignite on the first or second try.
I have tried to change sides of ballast and lamps and it is always the left side that will not ignite.
Any ideas how to solve this? Thanks.
Did you (or anyone else) notice any FM radio interference after the capacitor mod?
I get my audio through my AUX cable and occasionally CDs, so honestly never listen to the radio, that's interesting though never heard that as a complaint but I can see how it's feasible
The light output of HID is what kept me going back to find the right kit. For the E61 and W211, they were only for the fog lights but I kept looking for a kit that worked as the difference was night and day (sorry no pun intended). For the W204, it was for a headlight conversion kit, and most kits worked except when the switch was in the auto mode. All the cars I have, all have HID kits for the fogs and those that came with halogen headlight have been replaced with HID kits. None of them have start up or blinking issues anymore.
Try looking for kits with Umnitza, they may have one that'll work for you or have a return policy that will give you peace of mind trying. For CANBUS kits, I go to a local place close to me who sells them, and I have had very good luck with them.
Bought d1s and fogs in matching temps, they don't match either.
Anyone else have this problem from them?

I just finish install a HID kit and been testing for the past weeks.. This kits does NOT require a capacitor like other kit. Its "plug and play". Only modifcation you would need to do was enlarge the stock bulb hold to fit the HID bulb. I place the HID ballast inside my headlights (there's plenty of room) for a clean oem look. Most important it DOES NOT display the error code or required you to visit the dealership to turn on the HID option (=$$$$)... Oh.. NO FLICKER with engine off and on!!!!.

Here's pictures with only one HID installed on passenger side

both installed:

Finally, shot of my gauge.. look mom... NO ERROR


Enjoy.. any questions you can post here or pm me...

I would like to replace the entire headlight with factory HID's, do I get non adaptive ones or adaptive ones? plug and play besides going to the dealer to activate Xenon System on?
Thank You in advance
