One or more of the following conditions are exhibited:
 The Air Conditioning (A/C) does not cool, or the cooling performance is very weak.
 The A/C system cools, but the A/C Compressor is noisy. The noise is characterized as a grinding or
groaning noise.
 Either symptom may be intermittent.
 No DTCs are stored.
Note:
This technical bulletin MUST be read in its entirety. The A/C performance test must be completed before
performing this procedure to eliminate any other fault conditions. It is mandatory for all A/C Compressor
reimbursement. See TB 2043704 for information on performing the A/C performance test. All
documentation, pictures and printouts must be uploaded to WISE. See warranty section for more
information on uploading information in WISE.

Technical Background
The condition may be caused by a faulty -N280- A/C Compressor Regulator Valve (Sanden). The internal
components of the valve can be obstructed and incapable of full function. This loss of refrigerant
regulation from -N280- A/C Compressor Regulator Valve can cause noise from the air conditioning
compressor and/or affect the HVAC cooling.
Figure 1 -N280- A/C Compressor Regulator Valve 1K0260839
Note:
This bulletin applies to vehicle built with Sanden 1K0820808 B>H and 5C0820803 B>G A/C
Compressors only. The replacement -N280- A/C Compressor Regulator Valve is not compatible with
other Sanden Compressors. The -N280- A/C Compressor Regulator Valve is not compatible with any
Denso Compressors.
If a Denso A/C 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.
Figure 4. Robinair A/C Service
Unit.
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 A/C 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 and the Guided Fault Finding A/C performance test must be completed before performing this
procedure to eliminate any other fault conditions. Submit through the GFF paperless for reimbursement.
See TB 2043704 for information on performing the AC performance test.
Rule out a refrigerant circuit leak as the root cause. If the GFF performance test determines low
refrigerant this bulletin does not apply. The refrigerant leak should be resolved before continuing
diagnosis. Should the refrigerant volume be too low, investigate a potential refrigerant leak in the circuit.
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 A/C
Compressor -N280- A/C Compressor
Regulator Valve 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).
Figure 5. Checking N280 signal value Measuring Value
Block.
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.
Tip:
Figure 6. Equalized pressure condition. No pressure
generated from compressor.
An example of no pressure generation is when
the pressure readings on the high and low
sides are equalized in Figure 6.
Note:
If the gauge readings are showing normal A/C
Compressor operation per the Elsa Repair
Manual, this bulletin does not apply and further
diagnosis is required.

Removing/Installing the -N280- A/C Compressor Regulator Valve.
Recover the refrigerant from the system. Remove the -N280- A/C Compressor Regulator Valve using the
following procedure.
WARNING:
With the refrigerant circuit charged the -N280- A/C Compressor Regulator Valve is under pressure. Be
certain that the refrigerant circuit is completely discharged before removing the -N280- A/C Compressor
Regulator Valve.
Remove one of the A/C lines from the A/C Compressor to assure the pressure in the compressor is the
same as ambient pressure.
 Remove circlip-A- carefully.
Note:
Circlip must be reused.
 Carefully remove the -N280- A/C
Compressor Regulator Valve - -B- from the
A/C Compressor mount -C-, using a suitable
screwdriver -D-, for example (Figure 13).

 Assess the condition of the -N280- A/C
Compressor Regulator Valve bore and the
valve filter screen (Figure 14). If severe
contamination is found in valve bore there is
a risk of damaging the replacement valve on
installation In these cases the A/C
Compressor must be replaced.
Note:
Figure 14. Corrosion in the -N280- A/C Compressor
Regulator Valve bore.
A slight amount of debris or corrosion does not
present a risk and does not justify replacement
of the AC Compressor.
 Should severe contamination be found at
the valve filter screen (Figure 15) and A/C
Compressor replacement becomes
necessary, ensure that the refrigerant circuit
is flushed in the course of repair.
Note:
Figure 15: Severe contamination at the -N280- A/C
Compressor Regulator Valve filter screen.
Small random particles on the filter screen does
not constitute “severe” contamination and does
not justify replacement of the A/C Compressor
or A/C refrigerant circuit flush.
 If little or no corrosion or contamination is found perform Repair Procedure A: Replacing the -N280A/C Compressor Regulator Valve.
 If corrosion and contamination is found, perform Repair Procedure B: A/C Compressor replacement.
 Document the all workshop findings of this procedure on the repair order.
Repair Procedure A: Replacing the -N280- A/C Compressor Regulator Valve
Note:
If no contamination was found during the -N280- A/C Compressor Regulator Valve inspection flushing the
refrigerant circuit is not necessary and the Expansion Valve and Receiver Dryer do not need to be
replaced.

the circlip groove for dirt, and if necessary,
clean them carefully and thoroughly with a
clean, lint-free cloth (Figure 16).
Figure 16: Prepare mount for -N280- A/C Compressor
Regulator Valve installation.
Note:
Risk of damaging another -N280- A/C Compressor Regulator Valve or A/C Compressor may result due
to dirt contamination or damage to the sealing surfaces in the mount.
 If necessary, carefully clean the A/C Compressor mount -C- using only a clean, lint-free cloth. DO
NOT use compressed air.
 Make sure while cleaning the mount -C- that no dirt gets into the area underneath the O-ring sealing
surface -F- or the existing channels and none of the mount sealing surfaces become damaged.
 Check the O-rings -F-, -G- ,-H- and -E- (if
applicable) of the -N280- A/C Compressor
Regulator Valve -B- for damage.
 Coat the O-rings -F-, -G-, -H- and -E- (if
applicable) of the -N280- A/C Compressor
Regulator Valve -B- lightly with refrigerant oil
and check for proper seating (Figure 17).

 Evacuate and refill the refrigerant circuit.
Note:
When the -N280- A/C Compressor Regulator
Valve is replaced a photo copy of the A/C
Compressor label must be attached to the
repair order for supplier traceability.
Repair Procedure B: A/C Compressor replacement.
Note:
The refrigerant circuit must be flushed every time the A/C Compressor is replaced.
The replacement A/C Compressor comes with a full charge of oil for the entire refrigerant system.
Therefore the A/C circuit must be flushed of all original oil form the entire refrigerant circuit.
For this procedure always replace the Receiver Drier and Expansion Valve after flushing the refrigerant
circuit.
The flushing procedure can be found in Elsa at: Heating, Ventilation & Air Conditioning>>Refrigerant
