2.4 Factory Bi-fuel S60 2002MY - Fuel gauge stopped working?
 

2nd time this happened and its now concerning me, 1st time the fuel gauge stopped working and the car wouldn't switch to gas, eventually the gauge worked after about 2 miles and the car switch to gas as normal. This morning coming to work I noticed the gauge has stopped working, it "appeared" to still be running on gas, but I forgot about trying to switch it when I got to work and I think the gauge was working again (probably why I forgot about trying to switch it and that the gauge wasn't working) The DIM was repaired around 1 year ago, could this be a DIM fault or could I have an ECU problem with my LPG system??
