Hi Guys. Hopefully you will be able to help.

At cold start for the first 15 sec the engine is running slightly over 1000rpm and there is a sound after accelerating that it goes away after the first 15 sec. Have a listen at the video. Any ideas?

Any help would be appreciated.

Are you referring to the squeal right at the start?

Thank for the reply. I am referring to the sound after i accelerate. It sort of sound like a vacuum sound... not sure how to describe it..

What engine have you got?

1.4 - 138 HP. Is a Blue GT 13 Reg..

The 1.4 is a turbo engine, thats just the turbo spooling up and dumping the unused air
