Well i run lpg as well as petrol which is great as having a full bottle of 70 ltr tank and full petrol would get you very far without having to fill up.. but when you cross over from gas to petrol i can smell the difference in the cab. The exhaust is standard and was new about 6 years ago, not that its done that many miles to rot. But im thinking one of the heat exchangers might be leaking thats why i get the smell. I dont know of many with lpg convertions so is this smell normal in petrol runners as when i run on lpg i get nothing. All the back door seals are new and close well i thought it might be that dragging the fumes into the vw or its coming up the heat exchangers channel straight into the cab... It might be time for a new exhaust though looks new. Oh i use a beetle twin out to camper heat exchangers. Sent from my SM-G935F using Tapatalk
