Check cylinder head cover

Up to production 06/1999.

Crankcase ventilation out of order, engine can

sludge up and consume oil as a result

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).

Tires

D
For service conversions, the tire/disc wheel specifications and

dimensions should be compared with the entries in the
registration papers.

D
When mounting tires, the tires and rims must be carefully

matched in order to guarantee the concentricity of the wheel.

Identification of matching points on:

- Tires with a colored dot on the outside of the tire,

- Sheet steel disk wheel by a colored dot or punch mark on the

outside of the wheel,

- Perform this operation at the valve stem hole on light-alloy

disk wheels

With an additional paint spot or punch mark in the rim base

for the 140 Model Series.

D
Always replace the rubber valve.

-----------------------------------------------------------------------------------------
D

Damaged and defective tires must always be replaced. The

repair methods employed in the tire trade are not approved by

Mercedes-Benz. Small nicks (<0.8mm) on the tire's sidewall do

not usually pose a cause for concern, and continued use of

such tires is approved

D When replacing just one tire, install it on the front of the vehicle.

This does not apply to vehicles with different tires of varying

specifications on the front and rear wheels.

D
Only use tires listed in the valid Service Information bulletins

and repair instructions.

D
If the permissible maximum speed of an M+S tire is below the

maximum speed of the vehicle, an appropriate adhesive plate

must be attached in the driver's field of view.

-----------------------------------------------------------------------------------------

D
Tires permissible for higher speeds may be used.

D
Always fit all rims with tires of the same design, make and

version.

-----------------------------------------------------------------------------------------
D

Run in new tires for approx. 100 km at moderate speed.

D
Handed tires must be installed according to the arrow on the

side wall of the tire.

D
Tires are subject to an aging process with negative effects on

the properties of the tire. In order to ensure optimum

effectiveness in winter, M+S tires should not be used for longer

than 3 years.

-----------------------------------------------------------------------------------------

Tire pressure

(For specified values see tire pressure table in the fuel filler flap, on

the Vaneo BM 414 see B-pillar on the passenger side).
Too low tire pressure increases the rolling resistance and increases

the flexing energy of the tire. This causes the critical temperature limit

to be exceeded (carcass detachment) and destroys the tire. Respond

to loss of tire pressure by determining the source and replacing the

tire as indicated.

Cleaning

Using a spray wand with high-pressure nozzles to clean the wheel

can lead to tire damage. Such damage occurs especially on the tire

side walls. The following should be observed when using flat jet

nozzles:

Mounting in bearings

Before putting into storage, clean tires thoroughly and check for
damage and adequate tread depth. Mark the position and running

direction of the tires with chalk. Do not store tires outdoors. Under the

influence of sunlight, heat, moving air and ozone the rubber looses

elasticity and strength, ages more quickly and becomes cracked.

Storage areas should be dry, cool and dark. Avoid drafts by keeping

doors and windows closed as much as possible. Do not bring tires

into contact with gasoline, oil or other greases as they dissolve the

rubber.

Disposal

Collection, storage and disposal should be performed in accordance

with the legal requirements and the company's own regulations.
