P82.10-0212-02


Check

1
Drive vehicle to level surface
The vehicle level must not change when the

brakes are applied.

Vehicle must be in ready-for-the-road

condition (unladen weight, fuel tank full or

proper additional weight).

Correctly adjust tire pressure.

Load driver's seat with 75 kg or a person

(except USA)

2
Align headlamp adjustment tester to vehicle

and adjust height according to marking in lens

Follow the operating instructions for

headlamp beam setting equipment exactly

*WH58.30-Z-1002-09A


Danger!

Risk of accident
from vehicle starting off by

itself when engine running.
Risk of injury


suffered in the form of bruises or burns to the

hands when reaching in while the engine

cranks or runs
Secure vehicle to prevent it from moving off

by itself.

Wear closed and close-fitting work clothes.

Do not touch hot or rotating parts.

AS00.00-Z-0005-01A

3
Run engine and switch on low beam

4
Check headlamp range control for proper

function
(except USA)


The light beams from both headlamps should

change uniformly

5
Set headlamp range control switch to position 0

6
Check low beams
Adjust if necessary (except USA)

AP82.10-P-8260-01A


Due to the common reflector unit, the low

beams, high beams and fog lamps are

adjusted simultaneously.

US version:

Damage code
Cause
Remedy

Studies on engines 112/113 due to

excessive engine oil consumption have
indicated to date that excessive engine oil

consumption is not a general subject, but

rather can result from various causes.

The causes listed below may cause

excessive engine oil consumption individually

or in combination.

For commercially available tools for see

Workshop Equipment Manual

Cause 1:
Remedy 1:

00 001 70
Cast iron crust in right cylinder head behind

oil drain opening
1
Remove cast iron crust

AF18.00-P-8045A

Cause 2:
Remedy 2:

00 001 70
V-shaped material flaws (rough unhoned

points) on individual cylinder liners

Up to production 08/2000.
1

Check cylinder liners with piston at

bottom dead center.

Cause 3:
Remedy 3:

00 001 70
Single oil scraper rings with ring tension at

lower tolerance limit.

Up to production 06/1999.
1

Perform oil consumption test drive over

approx. 500 km.

AR18.00-P-0025AV
Exclude all other types of faults.

2
Remove/install/replace piston rings.

Install cleaned pistons with new piston

rings in the same cylinder.

Install piston rings with optimized ring

tension.

These piston rings are available as

replacement parts under the normal

replacement part number.

Cause 4:
Remedy 4:

00 001 70
Individual (right) cylinder heads with inner

porous points to air injection duct.
1
Check left/right cylinder bank.

If a cylinder bank is oily:
#
2
Remove/install/replace only this cylinder

head.

Individual engines with missing valve seals on

individual cylinders
1
Remove valve springs on affected

cylinder.

AR05.30-P-3500B

In this case, usually one cylinder is oily, oil

runs through valve cone into cylinder when

valve is open.

2
Check valve seal.

Cause 6:
Remedy 6:

00 001 70
1.5 mm hole missing on individual right

cylinder head covers at connection to

crankcase ventilation.
1
Check cylinder head cover

Up to production 06/1999.

Crankcase ventilation out of order, engine can

sludge up and consume oil as a result

Cylinder head cover not okay:

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).
