I purchased the tire repair kit mostly to top off my tires to its rated pressure (310 kPa) for my Model 3 (after about 4000 miles of driving, my tire pressure indicators are showing 2.9 bar or 290 kPa). I could not find any instruction manual online and the printed version uses tiny fonts. Anyway, the kit worked perfectly as all I had to do is to unwind the cable, connect it to the 12V port (hidden in the back compartment) and take the kit close to the tire, connect the black tube to the valve, set the switch to the pump icon and press the power button. Tire-1: done; Tire-2: nicely finished. When I went to Tire-3, the power button will do nothing. I disconnected and then reconnected everything; same result. The compressor did not hum anymore. I cannot find any contact info in the Tesla shop to see if the unit (most probably defective) can be replaced. Any help in this regard will be appreciated.
