If the flexible section is black rubber then the oil feed line will
need to be replaced.
Refer to Repair Instruction 11 42 200 “Remove and install /
renew the oil feed line for the exhaust turbocharger N63O2”
Do not remove the turbochargers!

4. Only if the oil feed lines were actively leaking oil.
Check the engine block (V-space) for engine oil residue and
clean as needed.
If there is leakage, the exhaust system, both exhaust
turbochargers, the lower heat shield, the complete exhaust
manifold and the oil-to-coolant heat exchanger needs to be
removed to clean this area.
Refer to the following repair instructions:
11 62 060 “Removing and installing/replacing the left exhaust
manifold (bank 5-8)”
11 62 065 “Removing and installing/replacing the right
exhaust manifold (bank 1-4)”
11 44 000 “Removing and installing/replacing the oil-tocoolant heat exchanger”
Wipe dry with a shop towel and rinse the residual oil with
cleaner via the drain hole and flush it out (see arrow).

5. If the lower transmission housing also has oil residue present
then it has to be cleaned via the opening (1). To do so,
remove the sealing cap (1) and sealing cap (2) and flush out
the excess engine oil residue. The sealing cap (2) may be
located on the left or the right side of the transmission
housing.
Reinstall both sealing caps when finished.

1. Locate and inspect the low temperature cooling system cap
(1) for traces of overflowing.

2. Do not remove the cap, if there are traces of wet or dried
coolant around the cap surface then it is overflowing.
If found overflowing, replace both charge air intercoolers.
When refilling the cooling system use only P/N 83 19 2 458
358 coolant which includes a corrosion inhibitor Frostex HT12.
If not leaking, do not replace any parts and do not drain
the cooling system.
Section 3: Inspect and Replace Map Thermostat and Electrical Harness

1. Locate the Map Thermostat Electrical Connector (1).

2. Remove the connector and check the pins in the connector
for traces of water or corrosion.
Example: This connector is already corroded.
If the pins in the connector are corroded, the engine wiring
harness and the characteristic map thermostat need to be
replaced.
Refer to the following Repair Instructions:
12 51 300 “Removing and installing/replacing the wiring
harness section of engine ignition control for cylinders 1-4”.
