Hi all, had my Ibiza in for cambelt kit and waterpump change yesterday. Seems to drive fine l, turbo engages when it should, and goes up the rev range no problem. However I've noticed the engine note has changed. I can hear the normal engine sound but on top of that there seems to be a more sporty raughty kind of sound. Is this normal? I'm in two minds about taking it back to the garage but won't bother if it's to be expected. Thanks a lot.
