-V.A.G 1342 -.
Start engine (engine oil temperature at
–
least 80°C).
Oil pressure when engine idling: min. 0,2
t
MPa (2 bar)
Oil pressure at 2000 rpm: 0.30 to 0.45
t
MPa (3 to 4.5 bar)
If the specified values are not reached:
Eliminate any mechanical damage, e. g.
–
bearing damage.
Replace pressure relief valve in the oil
–
filter holder → Chapter.
At a higher engine speed the oil pressure
