DQ200, 0AM (DSG 7)

0AM, DSG 7 (DSG 7) or DQ200 are different names for the robotic transmission with two dry clutches installed in some cars of the Volkswagen group. Maintenance of DSG 7 is to replace the transmission oil in the amount of 1.7 liters. In this case there are no check plugs. Filling of oil in DSG 7 is carried out strictly dosed.

Problems 0AM are associated with two nodes. Clutch and mechatronic. When the dual clutch is significantly worn, the 0AM mechatronic pump runs non-stop to maximize the output of the DSG 7 (DSG 7) clutch release rod. This causes the mechatronic electronic unit to overheat and melt the insulation of the DQ200 pump contacts. When this happens, the oil pump motor stops and the car does not respond to the shift knob. The short circuit causes the 0AM pump circuit fuse to melt.

The solution to this problem is to replace the 0AM electronic board with subsequent programming. Specialists of the company Mactrans with the help of an interface can program (sew) into an empty electronic block software both on the machine and without it. It is very important to realize that a short circuit inside the electronic control unit (ebu) 0AM does not happen accidentally. There are reasons for this. The next cause after a worn clutch is a hydraulic leak inside the DSG 7 (DSG 7) mechatronic. Realization of the problem, and that you are a victim of German technical progress comes in the form of a flashing key on the dashboard, and perpetually wet breather mechatronic 0AM. The pump motor does not stop after the ignition is turned on, it buzzes constantly. If nothing is done, the car will soon stop. There is only one way out - replacement of mechatronic DSG 7 (DSG 7). And the worst thing that can be in motion is the failure of the pressure sensor. In this case, the pressure in the system grows until the hydraulic accumulator does not shoot forward. After that, the car stops waiting for a tow truck.
