📋 Procedure

1. ⚠ Risk of damage to gearbox.When performing repairs, the breather opening on the mechatronic unit for dual clutch gearbox J743 ((rear arrow)) and the gearbox breather ((front left arrow)) must be sealed off to avoid loss of fluid.If any oil escapes from the hydraulic fluid section of the mechatronic unit for dual clutch gearbox J743, it is not possible to replenish it or check the level! It is not possible to check the fill level of the hydraulic fluid section of the mechatronic unit for dual clutch gearbox J743. If oil escapes from the gear oil section, it can only be rectified by changing the gear oil. It is not possible to check the fill level.If the level of oil/fluid is too high or too low in either of the parts, the function of the gearbox will be impaired.Depending on the version, the breather cap on the mechatronic unit is damaged irreparably during removal and must be renewed. — Pull off both breather caps (arrows) and close using clean plugs from engine bung setVAS 6122 to achieve an oil-tight seal. [Note: As an alternative to the engine bung setVAS 6122, the protective cap02M 409 120 can also be used to seal the gearbox.
