Yaris 1.3 Gls Making A Rasping Noise

[crazyman50000]

Only under acceleration. If you get up to 30mph in 2nd, take your foot off the accelerator - noise is gone. Stick your foot down, big horrible rasping noise that wasn't there before.

Had a quick look under the bonnet and found an air intake pipe had come off the filter so put that back on, but the noise is still there and seems to be comming from the engine.

Could the VVT-i be stuck in advance mode? Or is this something to do with the exhaust?

First problem Ive actually had with the car =\

Solved it! Air filter had come unclipped. Clipped it back on, noise has gone!

Air intake pipe should be held on with a clamp. It will have a screw to tighten to clamp the pipe in place. It may have been left untightened at the last service.
