Note: "7-speed dual clutch gearbox 0CW" filled with oil for a long time (fluids are designed for a long service life). For this reason, there is no need to check the oil level, a threaded hole plug for level control is not provided on this gearbox. Observe the general repair instructions.
If the gearbox is leaking or the mechatronics is defective, find and eliminate the faults. Then completely drain the oil from the gearbox and refill with new one.
Draining gear oil
Raise a / m. Place an oil collecting pan under the gearbox. Remove the oil drain plug - see arrow - on the KP.
Let the oil drain.
Note: When replacing the mechatronic unit, drain the remaining oil in the gearbox after removing the mechatronic unit using a bleeder for the diesel engine, e.g. -WS 5226-.
Install the oil drain screw.
Transmission oil filling
New oil is poured through the vent hole.
Note: If a gearbox is fitted, the air filter or the battery with battery holder must be removed to fill with oil, depending on the model and engine version. When disconnecting and connecting the battery cable to ground, additional work must be performed.
Remove air filter. Remove battery and battery bracket.
Remove the breather from the vent hole.
Install adapter -VAS 6262A- and adapter -VAS 6262/4-.
Before screwing the oil filling adapter -VAS 6262A- onto the oil container, measure the length of the bleed tube, dimension -a-, and if necessary, cut the tube to dimension -a-: 210 mm.
Note: Measure dimension -a- on the rod (starting from the green surface in the enlarged image) oil filling adapter -VAS 6262A-.
Screw oil container onto adapter -VAS 6262 A-.
Note: If the thread on the oil container does not fit the adapter -VAS 6262 A-, another adapter -VAS 6262/6- must be used.
Note: Use only oil for filling "7-speed DSG - 0CW". Shake the oil container before opening. The oil level cannot be checked. For correct refueling of the gearbox, it is necessary to pour a strictly prescribed amount of oil into it. Overfilling, as well as underfilling, negatively affects the operation of the gearbox.
Fill in the prescribed amount of oil.
Filling quantities
After refueling, remove the adapter from the gearbox.
Note: Clean the area around the ventilation hole with a cloth.
Install breather. Install the battery and battery bracket. Install the air filter.
