The most common fix is to restart the iDrive system by turning the car off, waiting 2-3 minutes, and restarting. If the screen stays black, the primary causes in the UAE are often a blown fuse, loose connections from rough roads, or the control unit failing due to extreme heat. Based on common issues at Dubai workshops, the sequence of checks for a GCC-spec Z4 is: check fuse F56 in the passenger-side panel, inspect for loose wiring harness connections (common after desert driving or on Jebel Jais roads), and finally test the head unit's power supply. For a 2020 Z4 in Dubai, a fuse replacement might cost around 20-50 AED at a Deira parts shop, while a control unit repair at a specialized German auto electrician in Al Quoz could range from 1,500 to 3,500 AED, not including the screen itself. The RTA Dubai's vehicle inspection guidelines highlight the importance of functional displays for safety, and MOI UAE traffic reports note electrical issues can arise from prolonged AC use in summer. A key factor is the Total Cost of Ownership (TCO): if the car is under the 5-year agency warranty from AGMC, the repair is often covered. If out of warranty, the annual cost for such an electrical fault can add 0.10-0.30 AED per km to your running costs over a year, depending on the fix.
