Hi there.
Got this Passat European version on the shop with oil pressure light on after 1500 rpm. It has 46.000 km/28,750 mi. The light blinks three times and then switches btw watch and warning light.
Change oil pressure sensor for OEM part and no results. Connected Pico Scope to analyse the pressure curve with transducer and fluctuates betweeen 1.75 at idle to 3,0 bar at 2000 rpm. Sensor is calibrated to 1,2 to 1,6 bar. The aceleration curve shows smooth incrementation on aceleration and and smooth on deceleration showing no losses or clogged system.
Changed the oil to 5W40 and still no results. Open the oil pan and checked the strainer to see any debris and it was clean. It has no knocking or any weird sound comming from engine when light is on.
I believe this car has no PWM oil valve controler.
Please help me out here.
Thank you
