Cause 7:

Remedy 7:

00 001 70

Engine oil sludging due to excessively long 
engine oil change intervals

Service information: Oil sludge

SI18.00-P-0010A

 If the service interval according to 

ASSYST is exceeded, the engine oil sludges 
up sooner or later depending on the oil 
quality, type of operation and operating time. 
Engine consumes oil. 
See Service Information.

1

Print out ASSYST printout.

2

Check oil change intervals

3

Inform vehicle owner.

4

Remove/install/replace piston rings.

AR03.10-P-7311BV

 Disassemble and clean sludged engines 

completely because dirty oil usually gets into 
clean-oil side due to clogged oil filter.

Cause 8:

Remedy 8:

00 001 70

Piston rings sticky or have coke deposits from 
engine oils (e.g. API-S in USA) in connection 
with regionally poor fuel quality.

 Always use engine oils according to 

Specifications for Operating Fluids 229.3, do 
not add special additives to engine oil and fuel

BB00.40-P-0229-03A

1

Remove/install/replace piston rings.

AR03.10-P-7311BV

Cause 9:

Remedy 9:

00 001 70

Piston ring wear due to excessive 
contamination/dust (model 163) through air 
intake system.

1

Remove/install/replace gaskets on air 
intake line and distribution element of 
partial load ventilation.

 e.g. due to incorrect assembly after 

workshop visit or embrittlement of gaskets

 The distribution element with optimized 

material will be available as of 11/ 2000 as a 
standard feature.

2

Remove/install/replace intake module.

 Exterior oil loss, e.g. due to cast iron 

porosity on left side of crankcase in area of 
engine support is not considered to be oil 
consumption

In the event of a customer complaint 
regarding the engine oil consumption, always 
determine the oil consumption definitely 
because the oil indicator lamp can come on 
due to other causes (e.g. defective oil sensor).
