I decided to service my Van Conversion as it is now 2 years old. Oil change went OK, although the oil filter and filter drain plug were very tight! I bought a round air filter which was listed for my van, but looking at the housing, it looks as though it is a different type, maybe the type attached? Has anyone replaced this type of air filter, as I have removed the screws I can see, but the cover does not want to come off? The fuel filter was also the wrong one, so a trip to Fiat tomorrow to get the right one. I bought from AutoDoc, but just been on their site, and I am out of time to return it! I will list them on here, so if they fit your van, let me know.
