Safety precautions when working on mechatronic unit for dual clutch gear‐
box -J743-
WARNING
System is under pressure!
♦ The mechatronic unit for dual clutch gearbox -J743- has
a pressure accumulator that maintains a system pressure
of up to 60 bar.
♦ The cover of the mechatronic unit for dual clutch gearbox
-J743- and the pressure accumulator must not be opened.
Note
The pressure of the pressure accumulator is software-controlled and is set by means of the pump to a nominal
pressure of max. 60 bar. At a pressure of 60 bar the pump is switched off. If the pressure drops to 42 bar due
to gear shifting operations, the pump is switched on again. In the event of software errors the generated pressure
might amount to 75 bar. At 75 bar the pressure relief valve opens automatically.
