There are significant differences in tail lamps wiring and operation between pre-facelift and facelift X5 models - unless you want a bunch of trouble, stick to lights designed for your year/model.

As far as coding, you can turn off cold monitoring if you want, if not they'll just flicker the first second you turn in your lights. Youlll have a brake force error if you don't turn off the adaptive braking but it'll never throw an error on the dash nor will it effect anything.

The pre-facelift tails use dual-filament lamps and normal 12v power to the lamps, from the LCM. The facelift models use single filament lamps that are dimmed by a PWM power system from the LCM - the single filament lamps are modulated to at least three different brightness levels, depending on the situation - normal tail light, first stage brake light and second stage brake light. This is why you need to add capacitors to non-facelift LED tails when fitted to a facelift model- the PWM signal won't work with the LEDS properly without some sort of averaging circuit (a capacitor). This averaging is done by the tungsten filament in normal incandescent tail lights. This PWM is nothing to do with cold-monitoring - although that is there too. The PWM system driving the tails cannot be controlled by coding - you would need to replace the LCM.

ohhhhh yea the 04's & up have adaptive braking, that along is a huge difference in electrical.

It's actually 03 and up that have the adaptive braking. Many of us have LED taillights with no issues, including me.

I didn't mean to infer that LED tails designed for pre-facelift cars won't work on facelift cars - just that unless you are handy with wires and a soldering iron (and are bloody careful!) it might be more than a mission for you. It's certainly not plug and play. We've seen a few fried LCM (LKM) modules on this forum - although not due to the fitment of LEDS - and it's probably best to avoid cooking up your LCM (LKM).
