What is DSG? What is the best DSG test device?

DSG stands for Direct-Shift Gearbox. Previously there was only manuel gearbox, then automatic gearboxes produced. After that VW found DSG gearbox. Unlike a conventional automatic gearbox, that has a torque converter instead of a traditional clutch, the DSG has two clutches. At the same time that you select one gear, the next is automatically pre-selected, this function enables much faster changes. If we compair it with other gear types, the DSG is more fuel efficient than a torque converter, because DSG waster less energy.

Simply this special gearbox has effectively two separate clutches that work together like as one unit, without a clutch pedal and with full automatic or semi-manual control.

What are the advantages of DSG?

The most hard-hitting advantage of the DSG is fast gear change that it provides. With the car that has DSG, you can experience rapid gear changes delivering a smooth flow of power that can actually help you save fuel.

General Advantage of the DSG gearboxes.

Lighting fast gear changes
It contains 7 gears
More km per Liter
Hard to notice the gearshift and no jerks.

How does DSG work?

Basicly if we explain how does DSG work, there are 6 speed in the DSG gerabox, the 1st, 3rd and 5th gears have their own clutch and the 2nd, 4th, and 6th gears have their own clutch. So, the next gear you’re about to change to is always already engaged. So DSG does not waste time.

What are the general malfucntions that ocur in DSG gearboxes?
There are several common faults that ocur on 7 speed DSG gearboxes.

Common faults of the DSG transmissions;

Internal high pressure hydraulic leaks: One of the common failers of the DSG is internal hydraulic leaks, this failure requires rebuild or complete replacement mechatronic unit. In order to fix this failer you need DSG repair kit.
TCU failure: This failure is also very common and requires replacement TCU or complete mechatronic unit. In order to check this failer you need a DSG test device. And also after you fix the problem, you should check it on the table with DSG test device.
External low pressure leaks: This failure is also very common, and you need to rebuild of mechatronic in order to fix this problem.

DQ200 DSG Fault codes:

06079 – Hydraulic pump, play protection
06300 – Function restriction, due to insufficient pressure build up
06293 – Function restriction due to pressure drop
P17BF – Hydraulic pump system overload protection

What is the best DSG tester?

Inorder to tell a tester best, it should be user-friendly, should have low cost and should serve complate solution. If we examine all these, you can clearly say that DSG test device that produced by Nitro Company is the best DSG tester.
