hi all I own a 2002 Octavia vrs, this is my first turbo car, and ive notice when it boosts something that can only be described as clutch slipping

for example if you put youre foot down at 3000 rpm its goes up to 4000 rpm and than comes back down to around 3500. It does it a few time when i put my foot down up to high revs

Any ideas?

clutch slipping

clutch slipping

lol it had a clutch when i first bought it

Needs another then.

i thought that but ive been back to the garage and all is fine, but with the heaters on it doesnt do it

So ill keep them on but theres got to be a problem some were
