Hi. I had activated trip computer on a 2006/7 Opel Astra H 1.6i, and worked all okay.

Now after 1-2 years, customer mounted LPG gas.

Everything on the trip works, but no Range, etc it shows Refuel almost all the time.

Car have petrol, and I reset it with scroll button on the steering wheel, it shows ---, and after some time instead of showing KM, it shows again Refuel.

I think maybe because customer drives certain kilometers on LPG, and car trip computer thinks there is no fuel anymore (ie. as it is consumed) but there is still petrol the same amount of petrol in the tank.

Any opinion? Regards!
