For anyone thinking of having the cam belt replaced on a mk3, I would definitely recommend the dephaser pulley is replaced at the same time and I’d be weary of buying one that hasn’t had it done. Mine was violently rattling occasionally on cold startup and was starting to feel sluggish, a new dephaser has sorted it. I know a lot of places (including Renault) don’t recommend having it replaced as part of the timing belt service, but be warned they definitely wear out! Shoutout to Mick @ Diamond Motors, top guy and really knows his stuff. I had mine done by him yesterday.
