Caution

There is a risk of damag‐

ing  the  decoupling  ele‐

ment between the partic‐

ulate  filter  and  NOx

reduction  catalytic  con‐

verter.  When  removing

and installing:

Do not bend the decou‐

pling element more than

10°.

Do not stretch the decou‐

pling element.

Do not damage the wire

mesh on the decoupling

element.

Use the Transportation

Lock - T10404- to secure

the decoupling element

from stretching.

❑ Removing and installing. Refer to

Hose connections are secured with either spring or hose

clamps.

Always replace clamp-type clips with spring-type clips.

Hose Clip Pliers - VAS6362- or the Hose Clip Pliers -

VAS6340- are recommended for installing spring clips.

Removing:

WARNING

When doing any assembly work, especially in the engine com‐

partment,  pay  attention  to  the  following  due  to  the  limited

space.

♦ Route all lines and wires in their original locations.
♦ For example, for fuel lines, hydraulic lines, EVAP system

lines, coolant and refrigerant lines, brake fluid lines and

vacuum lines.

♦ Make sure that there is sufficient clearance to all moving

or hot components.

– Remove the engine cover. Refer to

⇒ “1.4 Engine Cover, Removing and Installing”, page 90

 .

– Remove the intake hose -item 1- 

⇒ Item 1 (page 336)

 between

the Mass Airflow Sensor - G70- and the intake scoop. Loosen

the spring clamps using the Hose Clip Pliers - VAS6362- .

– Disconnect the »orange« connector for the Exhaust Gas Tem‐

perature Sensor 2 - G448- -1- as well as the »black« connector

for the Heated Oxygen Sensor - G39- -3- on the plenum cham‐

ber bulkhead.
