  Caution
Risk of damage to gearbox
t  Different types of gear oil are available for the „multitronic 0AW“ gearbox.
t  Use only the correct type of gear oil, as assigned to the gearbox code letters.
t  The gear oils must NOT be mixed, even in small quantities. This would result in leaks at the oil seals. Select correct gear oil for vehicle according to gearbox code letters → Electronic parts catalogue. Only the gear oil available as a replacement part for the „multitronic 0AW“ may be used in the front final drive.
t  The filler plug must always be renewed after checking the oil level. Always select correct type according to gearbox code letters in → Electronic parts catalogue. To prevent leaks on the gearbox, please check the new filler plug by comparing it with the old one.
t  The gear oil must NOT be mixed with other types of gear oil, even in small quantities. This would cause leakage on the gearbox.
–  After installing gearbox, check gear oil level in front final drive and correct as necessary → multitronic 0AW, front-wheel drive; Rep. gr.39.
