Understanding The Mechatronics Unit in Your DSG Gearbox
If you drive a VW, Audi, SEAT, or Skoda, you might have heard the term “mechatronics unit” when discussing your DSG automatic gearbox. But what exactly is it, and what does it do? The mechatronics unit is the brain behind the DSG gearbox, responsible for selecting gears and operating the clutches. While the DSG gearbox is often thought of as an automatic transmission, it actually functions more like a manual gearbox with clever enhancements. It uses two clutches to make gear changes seamless and, in some models, controls up to 7 gears. In simple terms, the mechatronics unit handles all the gear-changing tasks that you would normally do in a manual car.
If your car is automatic and less than 15 years old, there’s a good chance it has a DSG gearbox with a mechatronics unit. Not sure? As German car specialists, our team at Volks Autos in Sutton, Surrey, is always happy to check for you and provide expert advice on maintaining or repairing your vehicle.
How Do I Know If My Mechatronics Unit Has Failed?
The symptoms of a failing or failed mechatronics unit can vary depending on the gearbox type and the nature of the failure. Some of the more obvious signs include a complete loss of drive or certain gears not engaging. You might also notice “jerky” gear changes or hear grinding sounds when shifting gears. On some models, you might even see a warning message on the instrument cluster or flashing gear indicator lights.
Why Do Mechatronics Units Fail, And How Can I Prevent It?
The causes of failure can vary depending on the type of DSG gearbox. For instance, the 6-speed wet clutch type can fail electronically due to contaminants in the gearbox oil. Because this variant shares oil between the clutches and the mechatronics unit, it’s crucial to follow the manufacturer’s recommended gearbox oil and filter change schedule to prevent issues. Regular maintenance is essential to keeping these components in good condition.
The 7-speed dry clutch type, on the other hand, has its own set of common faults, such as internal issues within the mechatronics unit that can cause the hydraulic system to over-pressurise and leak externally.
