Mechatronic module for Your Volkswagen Touran 4 Door First Generation (2003-2015)

Mechatronic module  
Mechatronic unit for direct shift gearbox J743  
The mechatronic unit is the central gearbox control unit.  
lk  
Within it, the electronic control unit and the electrohydraulic control unit are combined to form one component.  
The mechatronic unit is flanged onto the gearbox, and is an autonomous u nit.  
It has a separate oil circuit, which is independent of the oil circuit for the mechanical gearbox.  
The advantages of this autonomous, compact unit are:  
- Apart from one sensor, all sensors and actuators  
are contained in the mechatronic unit.  
- Due to the separate oil circuit, no foreign material  
from the mechanical gearbox enters into the  
mechatronic unit.  
- The hydraulic fluid is specifically adapted to the  
requirements of the mechatronic unit.  
- Good low-temperature behaviour, as no  
compromise has to be made with the requirements  
of the gearbox in terms of viscosity behaviour.

The mechatronic unit's electronic control unit is the central gearbox control unit. All sensor signals and all signals  
from other control units come together here, and all actions are performed and monitored by it.  
11 sensors are integrated into the electronic control unit; only the gearbox input speed sender G182 is located  
lk  
outside of the control unit. The electronic control unit hydraulically controls and regulates eight solenoid valves for  
shifting the 7 gears and for actuating the clutch.  
The electronic control unit learns (adapts) the positions of the clutches and the positions of the gear selectors when  
a gear is engaged and takes what has been learnt into consideration for further operation of these components.
