Hey everyone,
A little background. I currently live in Okinawa, Japan and my ATTESSA pump and/or pressure switch has died on me. Here in Japan they only search and order parts per your VIN which generates the Nissan FAST part number spread sheets. Well the dealer thought ATTESSA was HICAS (he swore by it) until I gave him the part number 41610-05U00. It was then he finally figured out they discontinued the ATTESSA pumps and the pressure switch was not given a part number creating a dead in. Google is only showing me old, used, unknown status pumps and I cannot figure out if a BCNR33/BNR34 ATTESSA are compatible. Now for the issue.
Recently my 4WD light came on. Before people start lighting me up I have went through the process and searched forums. The computer flashes 18, 19 and I have went through the process of deduction per the FSM. In the end the pump as stopped working and/or the pressure switch has failed. Some times the light does not come on for a minute and the system works, but in the end the 4WD light will come on and deactivate the system. The pump used to be super loud, but now makes no noise. The reservoir was just below the MAX line, but for some reason it is well over filled (I did not add fluid to it).
Everyone says to replace the pressure switch, but NO ONE SAYS PART NUMBERS OR WHERE TO FIND ONE! I am looking for a new or rebuilt ATTESSA E-TS pump with pressure switch for a BNR32 that will last another 24 years. If it matters it is a 1992. Also there is no DIY for rebuilding the pump or who/where we can purchase a refurbished pump. So, could someone help point me to who/where I can find and purchase a ATTESSA pump with a pressure switch online? Japan is no help, go figure.
