Technical issues and repair guidelines

Generally, these gearboxes serve quite reliably for 2-5 years. The warranty of the automaker has been extended (only VW) up to five years. At this period the percentage of visitors to service centers is still quite high. Customers complain about the issues related to vibrations, kicks, jerking caused by the double-disk clutch, velocity sensors, chips in the gearbox that damage mechatronics.

First repairs of these sophisticated and highly-priced gearboxes are related to replacement of filters: external filters of heat exchanger and ATF, which should be changed with the external filter. Minor and repeated repair operations of DQ250 involve replacement of VFS solenoids, which get damaged by dirt from ATF and, as a result, lose their operating qualities related to changing the oil flow and its pressure. As a result, VFS solenoids become "rejected" by the control system. The reassembly of 02E -DQ250 gearbox with the replacement of rings, seals and filters is “a must” procedure to prolong the lifespan of its friction elements and solenoids.
