M9R, and 800 or 802 or 805 or 806 or 809 or 816 or 845 or 849
a Connect the particle filter pressure sensor connec-
tor.
a Clip the particle filter upstream temperature sensor
connector on its mounting.
a Connect the particle filter upstream temperature
sensor connector.
a Clip the particle filter downstream temperature sen-
sor connector on the exhaust heat shield.
a Connect the particle filter downstream temperature
sensor connector.
a Fit the exhaust heat shield.
a Refit:
- a clip on the exhaust heat shield,
- a new adapter union of the particle filter down-
stream temperature sensor when replacing the
particle filter or if the adapter union was loosened.
a Torque tighten the adapter union of the particle fil-
ter downstream temperature sensor (44 N.m) (if
equipped).
a Coat the threaded union of the particle filter down-
stream temperature sensor with COPPER-ALUMIN-
IUM LUBRICANT
consumables for the repair) (04B, Consumables -
Products).
a Refit the particle filter downstream temperature sen-
sor (if equipped).
Note:
Use an open-jawed spanner to keep the adapter
unions in place and do not loosen them. Any
adapter union that is loosened must be replaced.
a Torque tighten the particle filter downstream tem-
perature sensor (30 N.m).
a Refit a new adapter union of the particle filter down-
stream pressure measurement line when replacing
the particle filter or if the adapter union was loos-
ened.
a Torque tighten the adapter union of the particle fil-
ter downstream pressure measurement line (44
N.m).
a Coat the threaded union of the particle filter down-
stream pressure measurement line with COPPER-
ALUMINIUM LUBRICANT (see Vehicle: Parts
and consumables for the repair) (04B, Consum-
ables - Products).
EXHAUST
(see Vehicle: Parts and
a Refit the particle filter downstream pressure mea-
surement line.
Note:
Use an open-jawed spanner to keep the adapter
unions in place and do not loosen them. Any
adapter union that is loosened must be replaced.
a Torque tighten the particle filter downstream
pressure measurement line (21 N.m).
a Refit:
- the silencer (see 19B, Exhaust, Silencer: Remov-
al - Refitting, page 19B-64) (for vehicles produced
before 02/04/2008),
- a new exhaust sleeve (see 19B, Exhaust, Ex-
haust: Precautions for the repair, page 19B-18)
between the particle filter and the intermediate pipe
(for vehicles produced from 02/04/2008),
- the engine undertray.
a Apply the after repair procedure using the Diagnos-
tic tool :
- connect the Diagnostic tool,
- select « Injection computer » ,
- go to repair mode,
- display the « before/after repair procedure » for the
computer selected,
- select « Particle filter » in the « List of components
controlled by this computer » section,
- carry out the operations described in the « After re-
pair procedure » section.
