Bottom-fill funnel and adapter kit for VW and Audi DSG and 02J transaxles, so you can add ATF through the fill port and set the level to the factory overflow spec.
Changing the oil in a GTI, Jetta, Passat, Golf R, Audi A3 or TT with the six-speed DSG and finding there is no dipstick and no top fill hole? The 02E (DQ250) is filled from underneath and its level is set by overflow at a specific oil temperature. The CTA 3403 funnel kit is the shop tool for that job: an adapter that threads into the drain and check port, a length of clear hose, and a large funnel that holds a full liter with a mesh screen in the neck. It also threads into the side fill port of the 02J five-speed manual.
Volkswagen's Self-Study Program 308 describes the 02E as one common oil circuit: the same 7.2 liters of DSG oil apply both wet clutches, cool them, run the mechatronic hydraulics and lubricate the gears. Because one oil does everything, the level matters more than on most automatics. The drain port has an overflow standpipe behind it. You hang the funnel above the car, let gravity feed oil up through the hose into the case, then, once the oil reaches the temperature the procedure calls for, remove the adapter and let the excess run out of the standpipe until it slows to a drip. That leaves exactly the factory level. The tool does the same job as the factory fill tool VAS 6262, with a funnel in place of a bottle adapter.
A fill tool does not fix a mechanical fault. Scan the transmission module and read the fluid and clutch temperatures before blaming the level. Our DSG overheating guide explains which temperature readings matter, and the DQ250 mechatronic and clutch problems guide covers how a missed oil service turns into clutch and mechatronic damage. If the box is already slipping with fresh oil at the correct level, the clutches are worn, and a DQ250 master rebuild kit is the next step.
The listing covers the VW and Audi DQ250 (02E) six-speed wet DSG and the 02J five-speed manual transaxle. It is not the right tool for the seven-speed dry DQ200 (0AM): Gears Magazine notes that box has two separate sumps that are filled by measured capacity, not by overflow. If your car is a DQ500 or an Audi S tronic, check the fill port thread against the adapter or send us your year and VIN and we will check it before you order. Everything else we carry for dual-clutch boxes is on the DSG collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The DQ250 (02E) six-speed wet DSG in VW and Audi models, and the 02J five-speed manual transaxle, where it threads into the side fill port.
It is not the right tool. The DQ200 has two separate sumps that are filled by measured capacity rather than by the overflow level-set this kit is built for.
The gearbox holds 7.2 liters in total, but a drain only removes part of it, so the refill is less. Fill until oil runs from the check port at the specified temperature rather than pouring a fixed amount.
It is gravity fed through a long hose into a port low on the case. Hang the funnel as high as you can and let each liter drain before adding more.
No. It is the funnel, hose and port adapter. Use DSG oil to the G 052 182 specification in the DQ250.
