If the bracket for output shaft torque senders -G195- and -G196- - is damaged, refer to arrow - the mechatronics must be completely replaced. Touch your hand (without gloves) to ground before packing the mechatronics to discharge static electricity.
Carefully. The mechatronic unit for the dual-clutch gearbox -J743- may only be touched or touched after the electrostatic charge has been removed via a grounded object, eg the main ground contact. Never touch the plug-in contacts in the gearbox connector with your hands, so that a static discharge does not damage the control unit and mechatronics.
Carefully insert mechatronic unit for double clutch gearbox J743- into gearbox housing.
Pay attention to the correct position of the locating pin -A- in the gearbox housing -see arrow 1- and of the bracket for the output shaft torque sensors -G195- and -G196- -B- in the guide -see. Arrow 2 - on gearbox housing.
Note: Do not pinch the cable for input shaft torque sender -G182- and clutch temperature sender -G509-. When installing mechatronics for double clutch gearbox -J743-, do not pinch connector wire -A-. If the cable is damaged, the input shaft torque sender -0182-/clutch temperature sender -G509- must be replaced. Do not damage the long bracket for the output torque senders -G195- and -G196- on the back of the double clutch mechatronics unit -J743-.
Screw in new screws -1- to -10- by hand. Tighten the screws in sequence to 5 Nm and tighten by + 90° (¼ vol.). Insert the cable -A- first into the upper and then into the lower retaining tabs - see Fig. arrows-. Connect the connector and lock.
Replace both O-rings - see arrows - at the point of connection of the mechatronics. Lubricate O-rings with DSG oil. Clean sealing surfaces and remove oil residue. Pay attention to the correct position of the new oil sump seal. Install the oil sump. Do not pinch any wires or pipes.
Install new screws - see arrows - oil sump fasteners -A- and tighten crosswise in several stages to the specified torque.
Fit a new transmission oil pump cover -A- and tighten the screws -see Fig. arrows - in several stages by a given moment. Fit cable holder to oil sump and tighten nuts to 10 Nm.
Connect connector -A- for mechatronics as follows: Arrows -D- on mechatronics -B- and connector -A-, as well as projection -C- must line up and point upwards. Then carefully connect the connector -A- up to the stop and block the shutter by turning to the right - in the direction of the arrow -.
Connect lower coolant hose to radiator - see arrow-. Fill up the coolant.
Install the stabilizer bar strut, to do this, tighten the screws -1, 2 and 3 to the specified torque.
Connect battery wire to ground.
Carefully! Do not start the engine without oil in the gearbox and do not tow the vehicle.
Fill with transmission oil. Install the lower engine soundproofing cover. After installing mechatronics for double clutch gearbox -J743-, the -basic setting- must be carried out.
