Hi There,
Log on to the uk forum and find detailed instructions on how to dicconect the sensors, quite easy. The batteries tend to have a 4 year life, unfortunately the complete sensor has to be replaced.
Handy gadget, while it works! Asif
Bought a wrecked 2002 sc430 car came from Jersey. It had 17 inch Fomb 5 spoke Wheels and Dunlop Graphics Tires. I would like to find another wheel or sell other three,one was ruined in wreck.
