Hello, I have a problem there. I had my V70 converted to gas. The PRINS system was equipped with a 67l tank (reserveradmulde). Now I have the following problems: 1. Already after 300km the diode display shows red. When I then refuel, 32l go in. 2. If I just drive the car further, it jumps with the well-known “IchbinleerPiepen” at 400km on petrol. When I refuel, then 40l go in. The tanks are only up to 80% can be filled. But 80% of 67l are 53,6l. The must Now I saw a 53l tank in his car at the gas station and asked him how big the tank is. And look, 67l. He told me something about a membrane that can be adjusted and then he wouldn’t switch so early. But sounded like a dangerous half-knowledge. I would need reliable numbers when he would normally switch to petrol and would be interesting as long as the green diode indicates. Greeting André
