Hi guys, I'm hoping someone here can help me out with what seems to be a bit of an unusual problem.
I have a R33 GTR VSpec. When I turn the car on (start engine) the 4WD pump whines and works like it should? But after about 2-4 minutes (variable) the 4WD and A-LSD lights come on and the ECU in the boot flashes codes 53 "Pressure switch and circuit". These lights come on as soon as the pump stops. But if I start to drive the car before these lights come on (i.e. almost immediately after starting it up), the lights remain off and the pump works continuously during the journey. It only seems to stop on idle or when stationary for about 2-4minutes.
The fluid was low but I have topped it up (not bled it).
Has anyone else ever had this problem? Any suggestions on what this might be?
Any help much appreciated!!!
