Damage code
Cause
Remedy

07 206 D5
High-pressure pump

To verify whether high pressure pump is

damaged.

#

High pressure pump of common rail

injection system is damaged mechanically.

1
Remove/install/replace high pressure

pump.

When the high pressure pump of the common

rail injection system is damaged metal chips

and/or damage to the pump drive (timing

drive) can occur due to contamination of the

injection system components.
2
Turn high pressure pump by hand with

driver.

If mechanical resistance can be felt,

perform the following tests. Clarify additional

work with ESKULAB by specifying repair work:

#
3
Check driver of high pressure pump or

mount in sprocket for damage (visual

check).

If high pressure pump is locked:
#
4
Check timing

5
Check timing drive for damage.

In each case:
#
6
Remove/install/replace timing chain.

If timing deviates by a crankshaft angle of

more than 20 degrees (corresponding to one

tooth skipped):

#
7
Check pressure loss.

8
Open low pressure connection on high

pressure pump return (plastic line in

area of pressure regulator valve) and

check connection point in rail for chips.

If chips are present when checking

injection system:

#
9
Thoroughly clean all fuel low pressure

lines as well as feed and return lines.

Flush and blow out with compressed air.

10
Remove fuel preheater and fuel filter

with filter housing, replace.

Fuel preheater is only installed in models

202, 203 and 163.

11
Remove/install/replace fuel cooler at

vehicle and engine end.

Not installed in model 210 up to 6/99 and

model 168.

12
Remove fuel tank, replace.

On engine 628:
#

13
Remove/install/replace electric supply

pump.

14
Remove/install/replace injectors, rail

(including pressure regulation valve and

rail pressure sensor), high pressure

lines and injector leak oil rail.*

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:
#
2
Remove/install/replace cylinder head

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).
