I took my car into my local indy mech. to get the xenon=present setting turned on. They didn't really know what I was talking about, but said they would take a look. About 10 mins later he said that he could do it because the lighting module was not showing up on the system, and he thought there was something wrong with my lights. I told them it doesn't have to do with the lights, and it should be there. About 10 mins later he comes back saying they found it but the was a problem with the module, and tonight my lights still flicker.

Does anyone have step by step instructions that I can print out to hand them, or at least where they can find it in the SDS?
Thanks
