Hello! I picked up my new Arona TGI the day before yesterday. Now I have the first time completely filled up today. The CNG tank was empty before, so I drove on gasoline. Now the funny thing: After refueling during the drive home (about 60 kilometers largely highway) the car changed frequently (about three to four times) from CNG back to petrol and then back to CNG. Is this so normal or should I ask the dealer? Thanks in advance and many greetings alexanderhirmer
