Well this is the problem because the dealer so far does not any have any ideas on what the noise can be, they told me at the start that it was 'road noise'! Funny as in all the years i been driving i never heard road noise that goes away when you put your foot on the clutch.
How they left it at the moment is to put about 1700 miles on it and see if the noise gets any better, so far it hasn't
Ensure you have notified the dealer in writing of your problem so it is officially logged.
Keep a note of all dates, times and who etc you have spoken with
I have driven a Twingo same as yours and cannot recall any noisae.
