Well I have been putting up with this squeaking type noise from the front over small bumps for around 6 years (don't drive it much).
From time to time I tried spray lube on all the suspension bushes without getting an improvement.
In the end I read on another forum that it could be the Bonnet lock...which had never occurred to me.
Sure enough, applied some spray lube to it and the noise has gone.
Thought I'd post here just in case it helps someone else in the future find it a little quicker than I
