Question about HIDs on my 3.0si...

[lo66x5]

Hi all,
I'm new to this forum, and just bought a 2008 X5 3.0si, very nice car and just a got a quick question would like to ask. i have installed a sets of HIDs on my car, once I turned it on it works, after a few seconds the lights go off and a error message came up on my dashboard.
just wondering if anyone here experienced this situation?is there a way to get rid of the error message?a relay cable?

The HIDs that i bought from the guys said that is for BMW which can get rid of the error message with integrated digital ballst. but unfortunately it doesn't work...

p.s my x5 doesn't have xeon headlight optioned. what HIDs do you guys use?

Thanks...
