I had the same pixel problem. '03 4.4 at 82K miles and 6 years old, BMW NA did the "good faith" repair for me. They paid 75% for the new instrument panel and I paid O.5-hr labor at my local dealer. I also got a 15% discount on labor from my dealer. I ended up paying about $150 or was it $180?
BMW NA will consider the age/mileage of the vehicle, wheter or not you're the original owner, and how long you've been with BMW. I got 75% because the X is our 4th BMW in the past 20 years.
Give BMW NA a call. They'll probably offer to pay 50% for part...then you'll have to negotiate to get them to go higher. They used to give 100%, but not any more.
The MID pixel is not covered. I tried doing DIY fix, but ended up destroying the MID (note to self, don't mess with electronics

). Ended up getting a new one at my expense of course.
