The 7-speed preselective robotic transmission Audi DL501 or 0B5 has been produced by the company since 2008 and is installed on all-wheel drive versions of such models as A4, A6, A7, Q5, as well as Porsche Macan. This robotic gearbox with a pair of wet clutches is designed for longitudinally mounted engines.
DSG-7 family: DQ200, DQ381, DQ500, DL382, DL501.

In 2008, VW engineers developed a new dual-clutch, wet-clutch, preselective robotic transmission designed for longitudinally mounted models with torque up to 550 Nm. The transmission features a separate oil circuit: one for the mechanical component, and the other for the electronic-hydraulic transmission control system and the dual clutch unit. In 2010, a reinforced version of the transmission was released for V6 diesel engines with a torque of 600 Nm.

Disadvantages of the Audi DL501 gearbox
- The dual clutch unit and mechatronics of this robotic transmission share a single oil circuit, so the valve body valves wear out very quickly due to clutch wear products. Change the oil in automatic component as often as possible; this significantly increases its service life.
- The second most common problem with this transmission is regular electrical failures: the RPM sensor module and gear position sensor most often fail. Failure of the fork travel sensor is also common, requiring replacement of the entire control board.
- The mechanical component in this transmission is reliable, and problems occur after 200,000 km. The front support bearing of the clutch wears out most quickly, then its seat in the cover breaks, causing play. Then the bearing starts to spin.
- Failures of the ejector pump for clutch cooling are also common. The additional oil drain can also break, causing the clutch to overheat. Often, when replacing the clutch, it is necessary to replace the worn dual-mass flywheel as well.
