TCM 722.8 CVT VGS VGS2

The offer applies to repair / regeneration of the Mercedes automatic transmission controller / computer. The controller is installed in Mercedes A-class W169 and B-class W245 models. Each controller with a white flap is opened non-invasively (the flap in its entirety), older controllers with a black flap are opened on a cnc milling machine. All connections are fixed, unlike other companies that only repair broken ones, so that the unit does not come back for a new repair. Then the computer is connected to the test table where numerous tests are carried out at 100°C. After the tests with a positive result, the controller is glued together with the warranty and the manual sent to the customer.
