TL;DR: OEM Halogen to OEM LED swap - what's it gonna take?

So, I picked up my F54 Clubman S All4 in Feb...fantastic car, EXCEPT the halogen H4 headlights.
I tried multiple LED H4 upgrade bulbs but they all threw codes or flickered (most both).
My mom is getting rid of her F56 Cooper S which has the LED headlights, Fogs/DRL/Driving lights.
I mentioned I was jealous she had the LEDs and I didn't...she said I could have them all before she gets rid of it, but need to know what it will take?

All I can find is the info for aftermarket stuff in the threads.
Read a little about coding needed at the dealer but no solid answers. Is there DIY code options? If so, anyone have links to tutorials?

Looking for solid coding answers/links (if needed) and if there is any wiring differences. I need to be able to do it all in one go, before she sells it.
Also need to ensure hers or mine won't end up with any error codes, as she's trading hers into a place like Carmax/Carvana.
Hate to just let them go, when the stock halogen headlights are so damned awful!
TIA!

 

I know this is a month+ old now but there are LED H4 lights out there that are brighter than the stock LEDs. Also, no matter which way you go, if you don't code the car to LED lights, they'll flicker and you'll get bulb errors.

The lights I upgraded my wife's car with are the GTR Lighting Ultra 2 H4 bulbs. They are crazy bright but maintain the same beam pattern. I didn't have to adjust the lights at all.

 

The easiest way to do the coding is use the dimmer app and buy the recommended bluetooth OBDLink CX.

There's a control setting to disable checking the lights as part of the headlamp upgrade to LED. Once that is is coded, you can swap the headlight with no flicker and error free.
