TECHNICAL INFORMATION
Filling to the lower edge of the oil filler opening means that the front differential is overfilled. In some cases, this may lead to emerging oil from the ventilation opening on the front differential.
After having drained the front differential oil, repair the front differential or upon initial filling of a new replacement front differential, the transmission must be filled with 450 ml of oil.
