Aluminum Oil Filter Housing for DSG DQ250 GearboxThe main reason of the DSG robotic box failure comes from overheating. Even car designers also point out this problem, which is corrected in the newer DSG gearboxes where the construction material of the oil filter housing is steel corrugated aluminum in order to increase heat dissipation. Moreover, a common defection of the factory housing filter in the DSG 6 is the distraction during the removal which leads to oil leakage from the filter housing.
