Hi all I was looking for suggestion as I have 2009 pajero LWB 3.5 recently I did oil change for all like engine, ATF, transmission and differential all was changed with recommended grade and I started facing issue with diff lock indication after few mins drive in 2H which i never seen before since I bought this car in 2014 and now I felt something wrong with the oil or maybe the sensor malfunctioning after new oil can someone give some heads up about the actual reasons behind..
