Thanks for the info. Took out the flexible hose today, but nothing wrong there. Also got a spray to clean the air sensor. The other issue is at around 60 and in top gear, the car will start shaking if you try to accelerate.
I have exactly the same sound. Only seems to be present when idling and the twin air intakes shake. When the car is in drive it makes the car jolt. Has anyone got any idea yet?
I bought the same model last week and I am hearing the exact same sound. There is a video clip posted in this forum and people have commented, but no definite answers. Solved yours yet?
