Dan's reply is probably the best guess but I have one other idea.
It could be the starter bendix sticking and not allowing the starter to
disengage from the flywheel. If it is this it would be very loud until
it disengaged and probably reving the engine a bit would force it to
quit suddenly.

Its a 1.8 se manual, the noise is only there at start up from cold,
dissapears after
a couple of mins driving, there is no noise after that, drives well, no
noise when braking or anything else, only at start up. Sounds like a
"rattling / grating" noise. then dissapears when engine warmed up. also no
error codes. HTH.

Could be the heat sheild rattling until it warms up and expands a bit.
Could also be the insides of the cat doing the same - rattling until
it expands. The heat sheild is easy to check, just see if it moves
around when cold. If it is the inside of the cat coming apart, I would
assume that you'll see a Check Engine Light soon, as it will clog the
exhaust system.
