Condition
87 16 27 December 1, 2016 2044165 Supersedes Technical Bulletin V871619 dated October 6, 2016 to update
required documentation note under warranty.
Air Conditioning Does Not Cool and or Compressor is Noisy
One or more of the following conditions are exhibited:
 The air conditioning does not cool, or the cooling performance is very weak.
 The air conditioning system cools, but the compressor is noisy. The noise is characterized as a grinding or
groaning noise.
 Either symptom may be intermittent.
 No DTCs are stored.
Note:
The AC performance test must be completed before performing this procedure to eliminate any other
fault conditions. It is mandatory for all compressor reimbursement. See TB 2043704 for information on
performing the AC performance test.
Technical Background
The condition may be caused by a faulty A/C compressor regulator valve N280 (Sanden). The internal
components of the valve can be obstructed and incapable of full function. This loss of refrigerant regulation from
N280 can cause noise from the air conditioning compressor and/or affect the HVAC cooling.

Technical Bulletin
Note:
This bulletin applies to vehicle built with Sanden 1K0820808 B>H and 5C0820803 B>G compressors only. The
replacement N280 valve is not compatible with other Sanden compressors. The N280 valve is not compatible with
any Denso compressors.
If a Denso compressor is installed on the vehicle this bulletin does not apply. Further diagnosis is
required. See TB 2043704 for information on performing the AC performance test.
Production Solution
No production change required.
Service
Since either symptom may be intermittent, the diagnostic process can affect the reproducibility of the
condition. Begin the diagnosis by isolating the cause before performing the basic checks.
Connect both the refrigerant service station
(Figure 4) and the diagnostic tester to the
vehicle.

Technical Bulletin
Cases of noise:
When diagnosing cases of noise, use chassis ears or a technician’s stethoscope to make sure that the root cause
of the noise is from the air conditioning compressor. The noise can change or may be absent depending on the
setting on the HVAC control unit. In many cases, the noise is more pronounced with the system switched OFF.
Cases of low or no cooling performance:
Note:
All faults in Guided Fault Finding and the AC performance test must be completed before performing this
procedure to eliminate any other fault conditions. It is mandatory for all compressor reimbursement. See
TB 2043704 for information on performing the AC performance test.
Rule out a refrigerant circuit leak as the root cause. Evacuate the refrigerant circuit to determine the refrigerant
volume. The refrigerant volume will likely be in specification. Should the refrigerant volume be too low, investigate
a potential refrigerant leak in the circuit. It is not likely that the refrigerant level will be too high because if it is, a
DTC will be stored. If no system leak is determined, recharge the circuit with the specified amount of refrigerant
before proceeding.
Perform the following diagnostic steps:
With the engine at idle, switch the climate control unit to full cold and full fan.
Turn recirculation mode on and close all windows.
Using the diagnostic tester, go to Guided Functions.
Monitor the measuring value for the air
conditioner compressor regulating valve
N280 signal (Figure 5).
The actual and specified values will be
plausible and will show a normal regulating
range of current for cooling request (0.400 A
– 0.820 A).

Technical Bulletin
After verifying the compressor should be on
and operating check the gauge readings on
the Robinair® service station. If the gauges
show no pressure generation from the
compressor continue to the next step.
(Example of no pressure generation is
when the pressure readings on the high
and low sides are equalized in Figure 6).
Figure 6. Equalized pressure condition. No pressure
generated from compressor.
Note: If the gauge readings are
showing normal compressor operation per
the Elsa Repair Manual, this bulletin does
not apply and further diagnosis is
required.
Check that the compressor torque limiter has
not been activated (Figures 7a and 7b).
Note: If the torque limiter has been
released the N280 regulating valve is not at
fault. The compressor needs to be
replaced.
