Hello:
I have a BMW 325i ’06. I purchased an HID kit on ebay:

cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=280194667543

The first issue that I am having is a warning light on the dashboard, I am guessing is the infamous LBF problem I've being reading about in this forum. It does not say LBF, but is a light bulb with an exclamation sign. Someone told me that I have to reset the computer, so I went to the dealership, they refused to do anything and they also say that using those lights will void y warranty, they have the lights for about $4000 installed, so that’s out of the question.
I would like to know if these lights are going to cause any problem to my car.

Also how to fix this warning on my dashboard. I saw this post:

forums.bimmerforums.com/forum/showthread.php?t=203520&page=0&highlight=lbf+fix

but I don’t want to alter anything on the car, since it's under warranty. I have read something about flashing the computer but I am not sure what that means.

The second problem that I have is that the passenger side HID sometimes goes off and sometimes flickers, I am not sure if this is related to the first issue.
Also, I know this is a very broad question, but what am I risking by voiding the warranty on my car because of those lights? i.e. I am pretty sure that if my transmission breaks down they can’t refuse service because of the lights.

Thanks a lot in advance for all your help and I apologize if this has been answered before, I just couldn't find it.
