Oil level
Cold engine start
Effectivity: 912 i Series
OM Edition 1/Rev. 2
Oil level is increasing
Possible cause
Oil too cold during engine op-
eration.
Contamination with diesel fuel. Check fuel.
Engine hard to start at low temperature
Possible cause
Starting speed too low.
Low charge battery.
High oil pressure.
Oil pressure too low after cold
start.
NOTE: Oil pressure must be measured at idle at an oil tem-
perature of minimum 50 °C (120 °F).
Be sure the oil pressure does not go below mini-
mum at idle.
BRP-Powertrain
Remedy
Cover oil cooler surface, maintain the
oil temperature prescribed.
Remedy
Preheat engine.
Fit fully charged battery.
At cold start a pressure reading of up to
around 7 bar (102 psi) does not indi-
cate a malfunction.
Too much resistance in the oil suction
system at low temperatures due to cold
oil. Stop engine and preheat oil.
After a cold start the oil tank must be
observed and the pressure should be
above 1.5 bar (22 psi). Otherwise, the
speed must be lowered again, because
not enough cold oil can be sucked.
If oil pressure is reading lower than
1 bar (15 psi) oils with lower viscosity
are to be used.
