What This Product Does

The line carries refrigerant through its section of the air conditioning circuit. Its pipework and connections form part of the sealed system needed for refrigerant circulation and cabin cooling.


Functions

  • Transfers refrigerant between the wheel housing pipework and compressor.
  • Provides the specified rear refrigerant connection.
  • Forms part of the closed air conditioning circuit.


Technical Details

  • Brand: OE Match.
  • Position: Rear.
  • Component identification: intake pipe, wheel housing to compressor.
  • Supplied reference numbers: 99357309909 and 99357309903.
  • Diagram application note: 96-, C.2/C.4.


Symptoms of Fault

  • Cooling fades again following a refrigerant recharge.
  • Oil staining or leak-detection dye appears around pipe connections.
  • Inspection reveals corrosion, rubbing damage or deterioration at a joint.
  • A substantial leak may produce an audible hiss.

These signs warrant inspection rather than confirming that this particular line needs replacement.


Why Replacement Matters

A damaged or leaking refrigerant pipe needs repair before recharging the system. Replacing a defective line addresses the source of refrigerant loss; adding refrigerant alone does not resolve damaged pipework. Inspect the adjoining seals, connections and supports during the repair.


FAQs

Could renewing the O-rings solve the leak?
It may, where the pipe remains sound and testing locates the leak at a sealed connection. Corroded or damaged pipework requires separate attention.

Will a recharge alone fix declining cooling?
Not if refrigerant is escaping through this line or another component. Locate and rectify the leak before recharging.

What should I check before choosing this part?
Confirm the vehicle's model year, C2 or C4 application and reference numbers against the existing component.
