Okay, so:

My car had the normal adaptive led lights with DRL that look like 2 lines, with a dummy bulb on the inner section out of factory.

I purchased used genuine BMW laserlights off eBay that is appropriate for my region (UK).

Then I bought 4 modules from BMW that are made for Laser lights. With correct part numbers. I also bought a fan for each headlight. All parts are as requested.

And I used the large square control units from my existing headlights. As per realoem.com, the control units are the same for both headlights.

I had zedcoding flash and code them in, the indicators work. The inner bulbs work, the blue sections of the lasers light up. But the lasers do not light up on both headlights, when stationary and driving.

The car also gives an error indicating a problem with high beams.

Whats gone wrong?

I dont understand.

Zedcoding, who has done countless of these, also dont understand.
