Cause

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.*
