Genuine BMW tire repair kit/fix-a-flat. Self-contained module that uses its 12v battery to power a compressor and pump that re-inflates a tire to the correct pressure while simultaneously applying a BMW-approved sealant to the tire. It is untouched and exactly as it came with a 2026 BMW x1 (don't ask me what happened to that car, ugh). Module is guaranteed by BMW through 2031 and, if needed, the battery can be recharged by included USB cable. Never worry about a flat tire again - no need to change tires or wait for help, either. Peace of mind in a small black bag. Oh, yeah, it comes in the official BMW bag.
