ATF, topping off
With engine running.
- Pry off plug securing cap -arrow- with a screwdriver. The cap locking device will be destroyed, when doing this therefore always replace cap.
- Pull plug out of filler pipe.
Note: On some transmissions a cap with a spring retainer is installed. This cap can be used again.
- Fill with ATF using VAG 1924 until ATF runs out of level hole.
Note: An insufficient ATF filling as well as filling to excess affects the function of the transmission.
- Install new seal -arrow 1- to plug and tighten to 15 Nm
- Install sealing plug on filler pipe until the spring retainer lock locates, or
- Install plug on filler pipe and secure with a new cap -arrow 2-.
