irritating buzzing noise from back of the engine bay GTC!

Dear PPers,

any help on the following would be much appreciated, before i take this GTC to a dealer and have to sell off my first born. Ive recently been experiencing a tapping/buzzing noise, quite loud from right at the back of the engine bay, sounding like its coming from the drivers side. Its intermittent, and first arose a few months ago, stayed for a couple of weeks before disappearing for a few months and now reappearing.

Because its intermittent, it obviously disappeared when i last had it serviced a few weeks ago, and the HR Owen mentioned they couldnt find a fault.

The noise continues sometimes when the engine is off as well for a few seconds before stopping.

Any clues at all would be very much appreciated!!

Thanks very much. Sounds much less ominous than I feared. Out of interest, what were the symptoms in your case?

Wow. What exactly did you get done?
