Dont want to sound nasty but this isnt the first issue i've heard with CG clutches

Oops that doesn't sound good

There was a guy on here who's taking his back with the same issue soon as well I think

At least all the parts are under warranty

My polo does exactly what you have described. I am running the standard clutch and I just took it to a local garage for a quick look and they said it could be the release bearing. Not sure though, it seams like a few have the problem!

Just an update on this one!!

Been back to CG again today to have it looked at... The problem still couldn't be found but they replaced the slave cylinder free of charge!

Big thanks to Mick for doing this as it seems to have sorted the issue

The car feels like new now... I don't have to sit at traffic lights in neutral anymore!!
