Repair broken LED Angel Eye Unit

[Dark_stranger]

Guys, one of my 25w LED units has stopped working. I can clearly see 3 faulty LED's at the top and as the units cost me about £50 ($65) just over a year ago, I don't fancy buying another pair, just to use one. I have bought a new pair of 5w ones, but would like to try and fix my 25w ones. Has anyone tried this?

These are the ones I have.

2 things kill the LED units, heat, and cold monitoring checks.

If you disable the cold checks at startup so they aren't flickering every time you start the X you will get more life out of them. Once an LED fails there is no "repairing" of it.

I have a scanner now to switch off cold checks, but was hoping to replace the faulty LED's or all the LED's with something like the attached.

Give it a try if you want to.

I have (am), and have managed to split the 2 heat sink parts (either side of black\red fitting bit), they are simply screwed together with the aid of some resin to stick them together. The bottom section is purely a heat sink and nothing else. The top bit, seems a sealed unit, but guess the very top (non-heat sink) section is detachable. Just need to borrow the old mans vice to get a good grip and try and twist\prise it off.

Once that is done, hopefully its just a case of swapping out the LED board.

take a look at my post, in case that can help you.

I have this same pair and been trying to open them up. so under the black plastic has screws? did you break it off? post some new pictures of the progress. and I found them on eBay for $35us shipped from California

I know this issue has been done to death but as a point of clarification, it is not the pulsing of the LED’s during the cold monitoring checks that causes the issue per se.
It is the fact that BMW's implementation of the lamp check momentarily reverses the polarity of the voltage during the cold monitoring phase. If you splice a suitable diode in series with the LED’s you can still have the cold monitoring enabled without causing any issues.
The biggest killer of these types of LEDs is actually caused by being overdriven which causes excessive heat. Many manufacturers deliberately overdrive, or run the LED module in these units at its absolute maximum to extract as much light as possible, and to be competitive with other manufacturers. Unfortunately the LED driver circuitry is built into these LED modules so there’s not much the average Joe can do about this.

Just grab both heatsinks and twist. It will break the glue seal and unscrew. You will then have 3 parts, lower heatsink, black plastic part and upper heat sink.

I just now need to try and split the top section to access the LED's.
