The DQ381 gearbox, developed by Volkswagen Group, is a 7-speed dual-clutch transmission (DSG) used in various Volkswagen, Audi, SEAT, and Škoda models. Let’s delve into the positive and negative aspects of this transmission:
Pros:
- Efficiency: The DQ381 is designed as a smaller and lighter version of the DQ500, which significantly improves fuel consumption and reduces CO2 emissions1.
- Smooth Shifting: When properly calibrated, the DQ381 offers ultra-smooth up- and downshifting. It enhances driving comfort, especially during daily commutes and long journeys2.
- Improved Drivability: With the right tuning, the DQ381 can optimize gear shifts for a more pleasant driving experience. It adapts to the engine’s characteristics, ensuring seamless transitions3.
Cons:
- Price: One of the main drawbacks is the cost. Upgrading to the DQ381 may come with a premium, especially if you’re considering retrofitting it into an existing vehicle.
- Mechatronic Issues: The DQ381 mechatronic system can be a source of frustration. Some users report symptoms like missing gears, limp mode, and even complete gear blackout1. These issues may require professional attention.
- Oil Pump Vulnerability: The gearbox occasionally experiences oil loss due to malfunctions in the oil pump. This can trigger error codes and emergency operation modes4.
In summary, the DQ381 strikes a balance between efficiency and performance, but potential mechatronic challenges and cost considerations should be carefully weighed when evaluating this transmission for your vehicle
As stated with the right tuning , the DQ381 gearbox can be quite a pleasant gearbox to drive.
The main problem is that it upshifts way to early and this can be quite uncomfortable in the town driving conditions.
