I have had missing pixels on my IC since I bought the 2001 X5 new. The IC was replaced once under warranty, which corrected it for a while. But it's been missing pixels for the last 60K miles. I don't think it is the IC itself, as the missing pixels move around - they are sometimes different, and sometimes not missing at all. I think it is a software problem, but have no clue how to confirm that. I know this is a common problem. How have others dealt with it?
