Q: How to fix No airflow from specific vents or clicking noise behind dashboard in MINI Convertible (F57)?

The official service procedure assumes an extremely expensive replacement of the entire HVAC/IHKA casing (requiring the disassembly of the board). An alternative, cheaper solution is to install a special repair kit (3D spacer) that limits the flap's movement, which allows it to be unlocked and the flap end positions to be recalibrated (basic settings) using a diagnostic program without having to disassemble the interior. Before deciding to replace the heater, always check for error 801189. Manufacturing or purchasing a simple 3D repair spacer can save thousands of dollars in labor costs for dismantling the dashboard.
