Hoping one of the many X5 savants on this forum can offer their opinion. The pic below shows the fault (had to crop it to get it to upload). One other thing that happens when the fault occurs, my nav screen goes dark for a few seconds before the fault appears. Took it to the dealer they replaced the DSC control unit for 1800+ dollars which my extended warranty covered. Drove the X after the repair and still had the same problem! It's intermittent. Any thoughts?
