hi ya,
I have an 08 plate 197 which bought new and had nothing but problems with the gearbox. its ended up having a re-con box fitted 6 months ago under warrantee but its no better so its back at renault again.
mine has problems engaging gear when its cold and crunching into 2nd and 3rd and noisy whine from the box when driving along.
I'd take it back to renault if i were you. you might have to be persistent though, they said there was nothing wrong with mine originally.
