Any one got these for sale, I've identified the rattle in my engine bay is due to 2 of the bungs randomly going missing ! It's for an R26 for the bungs over the turbo if it makes any difference..
i had this problem mate, went to renault and bought 2, aparently they are from a 1.5 diesel as they dont sell them for the 2.0T... fitted them to my megane only to find 2 weeks later they had disapeared again but couldnt find them anywhere...
yeah I nearly lost my new ones 2 mins after replacing them. It seems if you push the cover down too firmly they pop out of the ring on the cover meaning they will just eventually fall off the metal pegs. Worrying really considering the belts are just to the side and if one got caught in them who knows !
