Hi mate I've got the same problem!
Anyway, today I've changed the starter and it's not fun really. After puting everything back the car started great, I drove it a little just to get the air off the cooling system.
Unfortunatelly when I tried to start it later today I got the same noise! :nonono: I guess I'm missing teeth on the flywheel :cry: :help:
I hope you'll have better luck!
