Vibration/knocking sound
Just got back from a holiday in Cornwall - driving on some very narrow roads with high walls with the windows open reflected all the engine sounds back to me, and I noticed when I pull away under heavy load in 2nd gear I hear a few small rapidfire knocks lasting a second or two.
I drove up and down this road a few times to test it out - If I go up through the gears "normally", it doesn't happen. It's only if I really floor the throttle in 2nd gear.
On normal roads, you cannot hear it at all, it really needs the reflection back from a close wall to hear it - so for all I know it's been doing this for years. I'm suspecting it's just something like the heat shield or the intake pipe rattling more than normal when being floored. But it's tricky to figure it out when 99.9% of the time you don't hear it.

I put a tie wrap around the connection between the airbox & intake pipe, problem fixed. Probably worth a shot as there is no damage done like with self tapping screws.

Ive had two reasons for this on my 65plate 1.2 QQ.
1. there is a nylon washer at the top if the Sus Strutt, its desigend to rotate with the Suss at low speed the "Clunk" I hear when moving the wheel is this simply locking into place...Hmmmm smells off.
2. To fix above problem they simply loosened all the suspension and tada it stopped...again smells funny
Could be the same for you.
