Annoying Beeping

I have just bought a second hand Atoz semi-auto 1.0 5 door for my daughter. It has been running well but now has an annoying beeping from the gearbox. Does anyone know what the problem is and how to fix it? In it's past history the semi-automatic gearbox has been replaced under warranty and it appears that it was intermittent problem again with the new gearbox.

Also, it has come without a operation manual. Does anyone know where I can find one? Many thanks. :clap: :liebe011:
