  • the windscreen wiper arms (see Windscreen wiper arm: Removal - Refitting) (85A, Wiping - Washing),
  • the scuttle panel grille (see Scuttle panel grille: Removal - Refitting) (56A, Exterior equipment),
  • the scoop under the scuttle panel grille (see Scoop under the scuttle panel grille: Removal - Refitting) (56A, Exterior equipment),
  • the front wheels (see Wheel: Removal - Refitting) (35A, Wheels and tyres),
  • the front wheel arch liners (see Front wheel arch liner: Removal - Refitting) (55A, Exterior protection),
  • the front bumper (see Front bumper: Removal - Refitting) (55A, Exterior protection).

K9K - D4F, and 784

• Remove the intercooler (see Intercooler: Removal - Refitting) (12B, Turbocharging).

F4R or K9K or M4R, and AIR CONDITIONING or CLIMATE CONTROL

• Remove:
  • the compressor pipe - intermediate pipe (see 62A, Air conditioning, Compressor - intermediate pipe connecting pipe: Removal - Refitting, 62A-51),
  • the expansion valve pipe - intermediate pipe (see 62A, Air conditioning, Expansion valve - intermediate pipe connecting pipe at the expansion valve outlet: Removal - Refitting, 62A-32).

D4F or K4J or K4M, and AIR CONDITIONING or CLIMATE CONTROL

• Remove the expansion valve - compressor pipe (see 62A, Air conditioning, Expansion valve - compressor connecting pipe: Removal - Refitting, 62A-41).

• Remove the front end panel (see Front end panel: Removal - Refitting) (42A, Upper front structure).

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Remove the mountings from the bulkhead soundproofing.
• Lift away the bulkhead soundproofing.
• Remove the connecting pipe bolt (1) on the expansion valve.
• Remove the connecting pipe from the expansion valve.

WARNING

In order to avoid any refrigerant leaks, do not damage (deform, twist, etc.) the pipe.

• Plug the openings on the connecting pipe and expansion valve.

WARNING

To prevent moisture from entering the system, place plugs on the cold loop components which are open to the air.

Note: Use blanking plugs for the fuel circuits with part no. 77 01 208 229 or 77 01 476 857 to plug any openings exposed to the open air. They must be clean. Do not use any which have already been used to plug a fuel circuit.

• Remove the connecting pipe bolt (2) on the dehydrator reservoir.
• Remove the connecting pipe on the dehydrator reservoir.

WARNING

In order to avoid any refrigerant leaks, do not damage (deform, twist, etc.) the pipe.

• Plug the openings on the connecting pipe and dehydrator reservoir.

• Unclip the expansion valve - dehydrator reservoir connecting pipe from the body.
• Remove the expansion valve - dehydrator reservoir connecting pipe.

REFITTING

I - REFITTING PREPARATION OPERATION

WARNING

Do not remove the blanking plugs from each component until the last moment.

Also, do not remove the components from their packaging until they are to be fitted to the vehicle.

• Clean the surface and seal of the pipe using ENGINE CLEANER (see Vehicle: Parts and consumables for the repair) (04B, Consumables - Products).

• Use a compressed air nozzle to blow on the surface and the seal of the connecting pipe.
• Lubricate the surface of the connecting pipe and the seal with air conditioning oil (see 62A, Air conditioning, Air conditioning: Parts and consumables for the repair, 62A-2).
• Remove the blanking plugs.

II - REFITTING OPERATION FOR PART CONCERNED

• Refit the expansion valve - dehydrator reservoir connecting pipe.
• Clip the expansion valve - dehydrator reservoir connecting pipe to the body.

• Fit the connecting pipe to the dehydrator reservoir.
• Refit the connecting pipe bolt (3) on the dehydrator reservoir.

• Fit the connecting pipe to the expansion valve.
• Refit the connecting pipe bolt (4) on the expansion valve.
• Tighten the connecting pipe bolts.
• Fit the bulkhead soundproofing.
• Refit the bulkhead soundproofing mountings.

III - FINAL OPERATION

• Refit the front end panel (see Front end panel: Removal - Refitting) (42A, Upper front structure).

D4F or K4J or K4M

• Refit the expansion valve - compressor pipe (see 62A, Air conditioning, Expansion valve - compressor connecting pipe: Removal - Refitting, 62A-41).

F4R or K9K or M4R
