I was just with my elk at the headlight test. I got into the conversation with mine. Among other things, we talked about the installation of gas systems in Volvos. Mine also offers this. There should now be conversion kits also for the D5 diesel. Only it would fail on the particle filter, as these are not yet available. Every diesel gets according to the also installed one filter. They would only wait for the approval of the manufacturer of this system and then The prices should be above the price of the petrol… Did you find out similar? Greetings Heiko
