BMW 128i Xenon Eagle Eyes Flickering Issue

[NathanB]

Hey
BMW 128i 2013 (E82)

I had upgraded original lights to Eagle Eyes Bi-Xenon
Everything was fine for years

I made accident and had to replace right side
I ordered the same part number as the light before - BMW 7273831-03 Valeo

But the problem is that right light is flickering (not the one I replaced)

It is random - it can run 10 minutes without flickering and then flicker

If I switch lights off and turn it back on xenon lights do not work

Sometimes it does work

What can be the issue and how can it be resolved?

Morning Nathan

Welcome to the Forum

A little confusing above you say you replaced the right light and the right light is flickering but not the one you replaced?? A quick look at Realoem tells me the part number was for the Left hand lamp. Is it the DRL (eagle Eyes) flickering or the Xenon Headlamps. Flickering could be a failing lamp (Bulb) or an issue with the Control unit

First check all the connections pay attention to the Earth points both sides the Xenon control units are high voltage so if you don't know what your doing get either a BMW Specialist or Auto Electrician to help. A Diagnostic scan may help as well.

Hope this helps

From the 1st video it seems the right hand outer lamp is flickers but the left (drivers side) is out

2nd video left lamp is on but after restart not

Have the Lamps (bulbs) been changed/checked? It looks as though that is where the issue is 

I would check all connections make sure all connectors are fully home same with the Lamp (bulb) connectors

If connecters are not home how come lights are on for sometimes 3 minutes ? 

same with bubls
technician told me if bulb had issue it would not even turn on

very confused

[Greydog]

If a connector is not fully home or has a poor connection vibration can cause intermittent contact. 

A lamp (the Bulb) can suffer the same sometimes a lengthy period before total failure 

Did the technician suggest a cure ? Was the technician a BMW one ?

If you turn on the ignition don't start the engine and turn on the lights what happens with out vibration.

If I turn on ignition and put lights on - sometimes they turn on sometimes they dont - and still flicker

i still haven't gone to official bmw technician because xenon are manually upgraded by me

OK so when you upgraded to Xenon did you use OEM parts or Aftermarket? If the parts are OEM are they correctly coded to the car? If not that is probably where the issue could be, the other culprit is in the wiring I know from helping several people who upgraded 5 series to LCI lights that often the correct connectors are needed and poor modification of the lighting loom was often a nightmare to correct. 

With your conversion you probably need a wiring modification to the Earth plus an inline resistor to stop flicker. I have also read that the Light switch may need changing, in earlier cars the FCM may need changing and re-programming. If you are OK with DIY on your car and know how to use a Multi Meter you should be able to sort it. You will need either a laptop with INPA/ISTA diagnostic software on it or the help of someone who has if any coding/programming is needed.
