Gas odour in LPG-V70?

Hello, since now 22tkm I am now on the road on car gas and very satisfied – especially when refueling (this morning again in Belgium for 43 ct/l). But since this afternoon something is different: the moose stood (fully fuelled) all day on the company parking lot. When I entered, I believed to detect light gas smell. However, only on the driver’s seat!? Neither in the trunk nor in the rear can a smell be detected. My wife also said that it smells “somehow different” but didn’t want to fix itself on gas. It was rebuilt by the Volvo specialist in the Westerwald, which does not exclude the dangers of mistakes, but minimizes them. What do you think? Do I or can it be that you only perceive the smell on the driver’s seat? Do you want to go to the “normal” symtoms? Unsettled greetings from Düsseldorf Bernd 🙂
