I bought an Octy VRS about three weeks ago. All has been going well except for the last couple of days. When I first start it up there doens't seem to be any power and when accelerating there is no turbo 'whistling'.

Also a couple of times when coming off the revs there has been a vibrating noise like a loose bearing. Yet when I stop and restart the car everything appears fine.

Any one any ideas?

Really need to get the fault codes read off.

Get it checked, maybe airflow fault

very simular to the problem i've been having on and off for a while now. i'm waiting for a new throttle body to be delivered to the dealers. they say this will fix the problem on mine but this is after them reading the error codes via Vag-com
