When starting the Octavia, its now bonging a couple of times.

Im sure this has only started happening since removing the standard stereo. Im guessing this is normal? Is there any way to stop it?

Do you start the engine then fasten your seatbelt?

Or have the "low coolant/overheating" light flashing?

No bong on mine using aftermarket stereo.

Ussually lights left on or seatbelt.

Oh dear, its not bad enough that the missus moans at me when i start the car without putting my seatbelt on first, now the blooming car does it too

Or it needs servicing? My Leon is doing that and flashing the spanner symbol.
