There is a dipstick / couple of them , one closer to radiator and one further back as described,
The circle is the front one.
The right hand side is where is is on my auto hatch look below intercooler
The left side arrow on picture Im pretty sure is where yours is on the turbo model either way have a look under teh intercooler at teh transmission tunnel / gear box and you should see it
