In this video I will disassembly a rear LED tail light from a BMW x5 e70 LCI to see what is failing inside of it ,and if can be repaired , and found out the the classic problem with cold soldering , most surely caused by thermal fluctuations , and of course because the new generation type of solder used , that is without lead ....

Hello! I am a really big fan of your work. I just want to point out that that light is off an E70 from 2007-2010 pre lci, the LCI have a little bit different configuration but same design. Love the work bro!

@BazvdB 2 года назад

Great video! Can we have more videos showing your knowledge on circuit boards?

BRAVO MAESTRO

@adamammar9955 2 года назад

hello, its a pre-LCI not an LCI

@MOvidiu 2 года назад

Yes you are right ✅️

@peeteraavisto2420 2 года назад

I have done similar repair on a F11 rear hatch tail light. The backside of the cluster has to be cut to remove the LED light circuit board. Main problem are also cold solder joints on the circuit board.

Amazing !

Hey! Do you maybe know what is the IC that is used for driving LES'd? It is marked E1S7n on it but to be honest I cannof find anything about this IC.

@MOvidiu 2 месяца назад

Unfortunately, the automotive industry is different! Sometimes, they use normal ICs, but they especially change the name /model. Sometimes, you can find someone like you and me who know electrics and show to others other times you need to struggle a little bit ! Unfortunately, I don't know.

@khefer1980 2 месяца назад

@@MOvidiu I took out scheme of my module and see that circuit is similar to LDO working as current stabilized source. Something like LM317 (positive) or LM337 (negative) so I think if the IC fails it will be possible to put there something that is accessible on market.

🎉 heya ! New sub from poland 😀 i want to custom tail lights in f10. Is it possible to cut them ? And then paint interior ? Thans for reply !

Bună. Voiam să te întreb care e cauza aburirii farurilor la un BMW E90 LCI cu xenon? Mi-am schimbat dispersoarele cu altele noi în vară, însă acum, de când a venit frigul, pe ambele faruri apare din partea de jos o dâră de condens de 10 - 15 mm grosime pe toată lungimea farurilor și urcă pe colțuri. La ambele e în mod identic. Care este cauza și ce aș putea face să scap de abur? Menționez că e doar abur, fără stropi, iar ambele sticle sunt perfect lipite (nu scapă aer), însă am văzut că farul are doar 3 aerisitoare (2 jos și 1 sus).

Buna Ovidiu, Pentru “Left lamp Malfunction” F26/X4…ai vreun video cum se poate repara pas cu pas? Merci!

Controler get very hot at 14vike 80/100c is that normal?I think no.

@GoGGuRO 2 года назад

The best !

@rokkovogel7973 2 года назад

I think this kind of LED control, and board is a sht. The basic level is funny, no cooling, and brightness is not enough. I don't understand E70 LCI why don't have full LED taillights?

@TheMrjogas Год назад

Yea controller get hot like 100c at 14.3v.

@grenzhochspannungshindernis Год назад

9:40 are the plastic tubes/sticks empty inside or filled with plastic? Whats inside those tubes? looks like threads or something else?

@MOvidiu Год назад

Hello, They are sold plastic

@jegerm6752 Год назад

Great video. It's really annoying that the damage is so minor yet the process takes a long time and a lot of skills lol. Most people would just buy new tail lights, so I'm glad there's someone like you on youtube showing us how to repair them. I wish you had a video on E60 lci tail lights. There's a lot of videos on e9x and f25 x5 but not e60.

@MOvidiu Год назад

Thanks for appreciation !

@mtbridingog9083 5 месяцев назад

It’s the same thing brother .. just a different wiring layout

@AMGmachine 2 года назад

Great research. But won't dust particles get inside the housing by cutting it open?

@MOvidiu 2 года назад

Hello, of course will enter, maybe with an air compressor you can blow out some of them, or better buy a new lamp 😀

@nicadair7700 Год назад

Use the soldering iron with the sharp edged cutting tool attachment and "melt" through the plastic. The dry joints on these circuit boards are the nemesis of BMW owners, they buy whole new light assemblies which are very expensive not knowing that the actual LEDs are fine, the problem being a simple "dry joint".
