BRILLIANT AND WORKS
Brilliant product if used in the correct way. I found that the signal didn't work holding the device to the alloy near the valve to pick up signal, so i found that holding the device to the tyre wall directly in line with the valve worked perfectly. Job done and all tyres re programmed and no more light flashing on my dashboard. Great device

Ok
If Anyone wanting to purchase this for the hyundai ix35, it is not compatible and will not turn off the light. Tried many times but light still stays on after multiple attempts to clear. More information about what vehicles it works on is needed.

I read that this should work on my 2018 BMW K1600GTL with the GS-911 scan tool I use for this bike. Navigated the menu system to the tire pressure monitor function then to "learn new sensor" and it easily programmed the 2 new tire pressure sensors. Do each one at a time. The ECM saw the new sensors immediately. The pressures on each tire registered immediately when starting out. Very happy to have this working now. This tool is a life saver. Worth every penny. Super easy and quick set up with GS-911. Be sure to check compatibility with your BMW or other motorcycle.
