Genuine Xenon headlight retrofit - Help required! Scraggles?

Hi Guys

First post so please be nice :D

I've got a 06 Cooper (R50) but I have a small dilema. I've bought a set of genuine and complete Mini xenon headlights (The facelift ones with projectors):

I've followed the instructions given by "Scraggles" in this the below thread but my xenon low beam lights still dont work properly. I've spliced the 1800uf capacitor into the yellow and brown wires of the input power in the lights access cover at the back (luckily i havent potted them yet as he did) All the other lights work fine but the xenon low beam is the issue :(

When the engine isnt running you can switch them on and they work perfectly. If you turn them on and then start the car they go out (as on the cars with xenons as standard) and come back on again which is as they should do ...however....

If you start the car and then want to switch them on they strobe like mad. They only work properly when the engine is off or if you start them before you start the car up. So if you want to put them on whilst your moving they will just strobe and wont stablise. :scared:

I cant' see whats gone wrong, does anybody else have the same issue? Do i require a bigger capcitor like 2700uf? Scraggles said this one would be fine?

Any help would be greatly appreciated

Aren’t the MOT people starting to get much stricter about xenons fitted without washers or an electronic levelling system?
thats what I have heard for all of you in the UK, but in the US I won’t have to worry about it in my state specially. Once a car passes inspection here, you don’t have to worry about anything unless you get pulled over for it.
