My Gransport is 2006 and hasn't ever had the charcoal filter replaced and I know that most opinions is that it is an item that doesn't really wear out but I'm just wondering whether some symptoms I'm experiencing could indicate that it should be done. The clues are strong fuel vapour smell on cold start (outside, not inside the cabin) and rhythmic brief hesitations every 5 to 10 seconds that occur after refuelling but settle after driving a minute or two. I also experience a few brief hesitations after the car has been sitting out in the hot Aussie sun but not every time. I think this also is a clue to a fuel vapour issue being the culprit. Using a scan tool, I also have modest negative long term fuel trims of about -15% to -17% both banks that indicates that the fuel injection pulse is being reduced because of a rich condition.
Have most other GS owners had their charcoal filters changed? How pricey is it to get it done? I mentioned it to my indie who didn't think it was necessary, saying they practically never need changing.
