Before beginning renewal of a wiring harness, first rectify the
cause of the damage (sharp edges on a body part, defective con‐
sumer, corrosion).
– When performing installation work on engine wiring harness,
observe the following:
Caution
♦ The procedure described in the workshop manual must be
strictly observed when disconnecting and reconnecting
the battery -A- .
♦ If a wire or a glow plug connector is damaged, the com‐
plete wiring harness including connector will have to be
renewed (connectors cannot be renewed separately).
DANGER!
♦ Follow safety precautions when working on the diesel in‐
jection system ⇒ 4-cyl. diesel engine (2.0 l engine, com‐
mon rail); Rep. gr. 23 .
♦ Note rules on cleanliness ⇒ 4-cyl. diesel engine (2.0 l en‐
gine, common rail); Rep. gr. 23 .
These instructions must always be complied with before and
during work!
WARNING

particular in the engine compartment, due to the narrow instal‐
lation conditions:
♦ Lines of all kinds (fuel, hydraulic fluid, activated charcoal
container system, coolant and refrigerant, brake fluid, vac‐
uum) and electric cables must be routed so as to restore
original line/cable routing.
