Servicing advice.

On the 6 speed Bora box the fill hole is on the front face of the gearbox and not too hard to get to and you have to fill it up until the level reaches the bottom of the fill hole, i.e. until it starts to dribble back out of the box, this job was easier for me by feeding the oil from above and through a plastic feed pipe.

I am not sure about the Octavia g'box but i would imagine it is a similar process
