5A43: DCT Pressure sensor, clutch 2, total failure
This could mean that the pressure sensor is reporting incorrect values, that the pressure sensor circuit has shorted or that the circuit is open.
First thing to do is to read the sensor data from pressure sensor on clutch 2. It's supposed to be within .2 and 1.8 bar pressure.
If the pressure sensor is reporting incorrectly, it needs to be replaced.
Otherwise there is a hardware issue or fluid issue.
This fault will cause clutch circuit 2 to be turned off, which will prevent selection of gears 2, 4 and 6.
Hope this helps.
