Please do...I ordered it new from dealer (306$ + coding). I guess mine was shot cause i tried cleaning and re-assemble over and over until i lost patience with it. Please report back :thumbup:

Hi, would your iDrive work after the tech cleaned the contacts?

For a few days but I ended up replacing it eventually.

Same here. I ended up buying at dealer and installed it myself. Dealer told me it needed to be coded after but no need in my case , it was just plug and play.

Thank you giodog2000 and soldmystang. my 08 X5 idrive just works sometime when press. I already took it apart and sprayed with DioxIT D5, but still not improve. I will try to order from dealer and install myself. Hopefully, it will not need to be coded like giodog2000's.

My I-Drive controller unit went bad a few months ago. I did extensive research on the part and was able to pick up a used one @ Weber Brothers Auto. Weber Brothers Auto ask for Greg 717-867-2151
It only cost $75 for a complete I-Drive controller and I didn't even need to re-code it. I spoke with a BMW tech and he said to just plug it in and see if everything works. Sure enough everything works.... B/c it is a used one from another X5 with similar options... Thank God...

Replaced iDrive controller today with new BMW part from Pelican for $284. Like others reported the click or tap function had failed. Hardest part was prying up the black plastic surround after pulling off knob. Single connector. No dealer computer required. Plug 'n Play!
