   Information 

   • An engine oil temperature of 90 - 100° Celsius is required in order to check the oil pressure correctly. 
   • Use the following tool for checking the engine oil pressure manually: 
   • > V.A.G 1342 - Oil Pressure Tester 
8. Start the engine and let it heat up until the engine oil temperature is at least 90° Celsius.
   1. 8.1 Read off the oil temperature on the Tester.
9. Rev to the specified test speed and read off the oil pressure on the pressure gauge.

   Engine speed [rpm]	Oil pressure p min. [bar]	Oil temperature t min. in °C
   Idle speed	1.35 - 1.5	90 - 100
   3, 000	2.35 ± 0.2	90 - 100
