DSG gearbox refill adapter (top fill service) - VAG

Adapts a funnel to the oil filter housing for a "top fill" method gearbox service. This way you don't have to mess around below the car with hoses and pumps and it's reasonably quick.

You need to use the O-ring from the old filter inside the adapter so that it can seal properly against the oil filter housing:

I used a funnel like the one below and it took around 15 mins to fill 5L of DSG fluid in my A3. You can adapt the file to whatever funnel/hose you're using (the longer the funnel, the quicker it will fill). Make sure the funnel tip has a decent seal against the adapter.

Printing Instructions:

I would just suggest to use a wall count of at least 3. Make sure it's clean from loose bits of plastic from the printing process before using it.
