Does not look good... Something is definitely wrong..
1st step: -> Read out raw data [clutch 1 pressure sensor, clutch 2 pressure sensor]
Tolerance range: 0.2 bar < pressure < 1.8 bar
1st step: Case 1: Pressure in one of the / both clutches
outside tolerance range 2nd step: Defective pressure
sensor(s)
=> Replace E-module
1st step: Case 2: Pressure in both clutches within tolerance
range 2nd step: => Continue with fault analysis
2nd step: Read out fault category
Precondition: Both transmission units in neutral, engine running
2nd step: Fault category 0, 2 (undefined, offset error):
=> Apply pressure to both clutches
Test routine 'Test_Offset_K1-2_02 '
2nd step: Case 1: Pressure difference </= 0.5 bar 3rd step:
=> Delete diagnostic fault code
2nd step: Case 2: Pressure difference > 0.5 bar 3rd step:
Pressure sensor offset too high
=> Replace E-module
2nd Fault category 4, 8 (short circuit or open wire):
Fault status
2nd step: Case 1: Persistent error 3rd step: Defective
pressure sensor(s)
=> Replace E-module
2nd step: Case 2: Sporadic error 3rd step: => Delete
diagnostic fault code
Good luck and keep us updated. Make sure the transmission has the proper amount of fluid as I've seen the units leak before causing failed clutches and low hydraulic pressure. It's strange to see these faults on both clutches.
