Differential fill point
I need to know how to fill the
differential fluid and what fluid to put
in (automatic transmission fluid or
Differential oil is added through a 17MM allen head bolt on the side of the differential. It's full when the fluid level is at the bottom of the bolt hole(starts to leak out when filled, or you can reach in with your finger and feel the oil). ATF needs to be checked with vagcom or similar scan tool to check temperature. At proper temperature, a small allen head bolt on the trans pan gets removed, and fluid drips from there when full. Fluid must be pumped in with proper equipment.
