Pinpoint Test C: High And Low Pressure System Pressure Gauges Reading Too Low Tests
WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
- C1: HIGH AND LOW PRESSURE SYSTEM PRESSURE GAUGES READING TOO LOW TEST 1
- Low pressures in the air conditioning system can be caused by low refrigerant. Using the Jaguar Land Rover approved equipment, recover the refrigerant
- Compare the weight of the recovered refrigerant against the vehicle specification
Is the weight of the recovered refrigerant low?
Yes: If the weight of the recovered refrigerant is low, this indicates a leak in the system GO to PINPOINT TEST A
No: GO to C2.
- C2: HIGH AND LOW PRESSURE SYSTEM PRESSURE GAUGES READING TOO LOW TEST 2
- Visually check for damage and internal restrictions between the two charging ports of the system, on the evaporator side of the system
Is there damage to the system between the two charge ports, that could cause a restriction to the flow of refrigerant in the system?
Yes: If there is damage to the system between the two charge ports, repair or replace the affected pipe work as necessary
No: If there is no damage to the system between the two charge ports, confirm the charging station is connected correctly at charging ports and retest
