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:
This technical bulletin MUST be read in its entirety. 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. 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 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 (Figure 1).
Figure 1 N280 Refrigerant Regulating Valve 5Q0260839A
Note:
This bulletin applies to vehicle built with Sanden 5Q0820803C, 5Q0820803E and 5Q0820803G
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.
Production Solution
Improved -N280- valve for the Sanden A/C compressor CW34/16.

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
2) and the diagnostic tester to the vehicle.
Figure 2. 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 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 and the Guided Fault Finding AC performance test must be completed before performing this
procedure to eliminate any other fault conditions. Submit GFF log with performance test through 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
air conditioner compressor regulating
valve N280 signal (Figure 3).
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 3. 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.
(Example of no pressure generation is when
the pressure readings on the high and low
sides are equalized in Figure 4).
Figure 4. 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 (Figure 5b).
Note: If the torque limiter has been
released the N280 regulating valve is not
at fault. The compressor needs to be
replaced.

Recover the refrigerant from the system. Remove the N280 valve using the following procedure.
WARNING:
With the refrigerant circuit charged the N280 valve is under pressure. Be certain that the
refrigerant circuit is completely discharged before removing the N280 valve.
Remove one of the A/C lines from the compressor to assure the pressure in the compressor is the
same as ambient pressure.

Note:
Circlip must be reused.
2. Carefully remove the A/C Compressor
Regulator Valve -N280- -B- from the A/C
compressor mount -C-, using a suitable
screwdriver -D-, for example (Figure 10).
Figure 10. Circlip / N280 removal
Assess the condition of the N280 valve bore and
the valve filter screen (Figure 11). 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:
A slight amount of debris or corrosion does
not present a risk and does not justify
replacement of the AC compressor.
Figure 11. Corrosion in the N280 valve bore.
Should severe contamination be found at the
valve filter screen (Figure 12) and A/C
compressor replacement becomes necessary,
ensure that the refrigerant circuit is flushed in the
course of repair.
Note:
Figure 12: Severe contamination at the N280 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.

 If little or no corrosion or contamination is found perform Repair Procedure A: Replacing the N280
regulating 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 regulating valve
1. Check the A/C compressor mount C- and the circlip groove for dirt, and if
necessary, clean them carefully and
thoroughly with a clean, lint-free cloth
(Figure 13).
Figure 13: Prepare mount for N280 installation.
Note:
Risk of damaging another N280 Valve or 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.
1. Check the O-rings -F-, -G- ,-Hand -E- (if applicable) of the A/C
Compressor Regulator Valve N280- -B- for damage.
2. Coat the O-rings -F-, -G-, -H- and E- (if applicable) of the A/C
Compressor Regulator Valve N280- -B- lightly with refrigerant oil
and check for proper seating
(Figure 14).
Figure 14. Check and prepare N280 o-rings
3. Insert the A/C Compressor Regulator Valve -N280- -B- until the stop in the A/C compressor mount -C-.
4. Re install circlip -A-.

Repair Procedure B: Air conditioning 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 R134a Servicing >>00 General Technical Data>> Refrigerant circuit
