Test conditions
•
Oil level o.k.
•
Engine oil temperature at least 80°C (radiator fan must have
run once).
Note
The oil pump is regulated and has 2 pressure levels. Pressure
♦
levels are checked after each other.
While running in or in emergency running mode, the oil pump
♦
will only deliver in the high pressure level.
The oil pressure depends on the engine oil temperature. At an
♦
oil temperature of 80 °C, the mean value (approx.) must be
attained.
Test sequence
– Remove connector -arrow- from the oil pressure switch for re‐
duced oil pressure - F378- .
– Place cloths under bracket for auxiliary units to catch escaping
coolant.
– Unscrew the oil pressure switch for reduced oil pressure -
F378- -1-.
– Screw in oil testing device - V.A.G 1342- into the oil filter holder
instead of the oil pressure switch.
– Screw in the oil pressure switch for reduced oil pressure -
F378- into the oil testing device - V.A.G 1342- .
– Start the engine and check the oil pressure at the indicated
speed.
•
Oil pressure in idle: 0.085...0.16 MPa (0.85..1.6 bar)
Note
While running in, the oil pressure at 2000 rpm can be 0.3...0.4
MPa (3 ... 4 bar).
•
Oil pressure at 2000 rpm: 0.12...0.16 MPa (1.2..1.6 bar)
– Powerful press on the gas pedal as far as it goes- the engine
speed will increase to 3700 rpm and for 5 seconds the oil
pressure will increase to 0.3...0.4 MPa (3...4 bar). Afterwards,
the oil pressure will drop to 0.12...0.16 MPa (1.2...1.6 bar).
– Switch engine off.
– Remove the sound dampening system ⇒ Body Work; Rep.
