A6 Quattro Wagon V6-3.0L (AVK) (2002)
c. Screw oil pressure switch (Figure 1, Point 2) into VAG1342.
d. Start engine and allow engine oil to reach a temperature of 80°C +1, -2°C. Check engine oil temperature with Instrument Panel- Measuring Value
Block 50, position 3, address 17 or check MVB 134 point 1.
Note:
Figure 2 shows the relationship between oil temperature and oil pressure.
For example: The engine tested here has an oil pressure of 1.75bar at 80°C but measured at 90°C has a pressure of only 1.3bar. A 10°C difference in oil
temperature resulted in a 0.5 bar pressure difference. This is 33% of the specified value. This demonstrates how important it is to measure at 80°C +1, -2
°C.
Engine Oil Pressure Specifications at 80°C +1 -2°C
^ Relative oil pressure at idling speed: 1.5 bar
^ Relative oil pressure at 2,000 RPM: 3.0 bar
2. If oil pressure meets specifications, install new oil pressure switch. See parts list.
No further repairs are needed.
