Hello, I am visiting you from E31 forum (I own a BMW 850) and I am a new owner of a 2008 black Z4.

I need some help from you because I am new.

My new Z4 has standard A/C controls. I have found at eBay the auto climate control (used part) (the panel with the buttons in the middle of the dash) in excellent condition. If I replace it, do I convert my system to auto or also I need to replace other parts? (EML programming for example etc).

Also can you recommend me a good Xenon KIT on the NET which fits our cars perfect?

Thank you in advance for your help
