DSG Mechatronic Unit

(Direct Shift Gearbox)


Many cars, mostly Volkswagens and Audis, have these unique advanced dual-clutch automatic transmissions. They have been around for a few years now and are hailed as an evolutionary step forward from the traditional transmission.

The mechatronic unit is a computerised control part of the dual-clutch system. It is complex and hard to troubleshoot when things go awry. When they do go bad, the dash will normally flash "PNDRS," and you will basically shut down wherever you are. You may be able to limp home in certain gears, or you may be stranded.

The mechatronics are housed in the gearbox, surrounded by special DSG oil. They make up the central control unit. All sensor signals and all signals from other control units come together at this point, and all actions are initiated and monitored from here.

VW has made over 1 million DSG transmissions. Most are working fine with no problems, as long as the owner maintains them by changing the fluid every 40,000 miles and properly filling them to the correct level.
