Just a small gripe, had the Rangie a couple of months, had the odd glitch to sort out but touchwood it's been quite well behaved. My issue is the amount of time it needs to warm up before switching over to LPG. For a month or so after purchase the switchover would be within a few miles, however over the last few weeks the switch doesn't occur till the car is fully warm and the gauge is at normal running temp.

Any ideas as to the causes of the excessive delay.

Thanks Nick
