I purchased them from renault over a year ago as well, should have got more, I found a new one on eBay and Mike was over for some over parts and before I could unwrap the Fog light he was on the phone to somebody else offering me good money for it. Thats what lead me to believe they are not available any more.
I know a lot of people use the same sales technique or add stupid mark ups on the items to put them on eBay, if the item is new they are more than likely available from Renault, latest case I have seen is the Rear seat caps over the hinges, these are available at just over £1 each from renault, people are trying to sell them for £20 delivered on eBay, nothing quite like making money out of people
likewise with boost hose rubber strap is about 300% markup and many other items I have got from renault in the past.
Valeo clutches I am not sure how available they are or what prices people are getting them for and can enquire about these as well if people are after them.
