Condition
87 15 09 July 8, 2015 2038368 Supersedes Technical Bulletin V871412 dated December 8, 2014 to include Golf
SportWagen applicability.
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.

Technical Background
The condition may be caused by a faulty A/C compressor regulator valve (N280). 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.

Production Solution
Final production countermeasures pending.

Technical Bulletin
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.
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:
Perform the following diagnostic steps:
1. Connect a manifold gauge set to monitor the refrigerant circuit pressures.
2. With the engine at idle, switch the climate control unit to full cold and full fan.
3. Using the diagnostic tester, monitor the measuring value for the air conditioner compressor regulating valve
N280 signal. The actual and specified values will be plausible and will show a normal regulating range of
current for cooling request (0.600 A – 0.820 A). However, there will be equalized pressure readings on the high
and low sides of the circuit (no pressure generation from the compressor).
4. 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 great since this should store a DTC.
5. If the air conditioning compressor is found to be the root cause of either of these conditions, Replace the
compressor.

Technical Bulletin
Note:
The N280 regulating valve is not available as a replacement part apart from the compressor assembly.
Air conditioning compressor replacement:
The originally installed compressor on the MY
2015 Golf/GTI is manufactured by Sanden
(Figure 1). The replacement compressor is
manufactured by Denso (Figure 2).

Note:

Figure 1: Sanden compressor identification tag.

All MY2015 GTI/Golf, SportWagen have
Sanden factory compressors. The
compressor should be replaced with Denso
5Q0820803F.
It is necessary to flush the system to clean
the refrigerant circuit of Sanden PAG. Failure
to do so can cause damage to the new
compressor.

Figure 2: Denso compressor identification tag.
 The flushing procedure can be found in Elsa at: Heating, Ventilation & Air Conditioning>>Refrigerant R134a
Servicing >>00 General Technical Data>> Refrigerant circuit removing contaminates>>Refrigerant Circuit,
Cleaning (Flushing), with Refrigerant R134a. The procedure is also described in Technical Service Bulletin
2019947.
 The correct adapters for the 2015 Golf/GTI can be found in Elsa at: Ventilation & Air Conditioning>>Refrigerant
R134a Servicing >>00 General Technical Data>> Refrigerant circuit removing contaminates>>Refrigerant
Circuit, Cleaning (Flushing), with Refrigerant R134a >>Adapter for Assembling Flushing Circuit.
Note
This bulletin is specifically for N280 malfunction. The expansion valve can be reinstalled after the flushing
procedure.

Technical Bulletin
The replacement compressor will come with the
specified type of PAG oil for the compressor
(Figure 3).
Note:

Figure 3: Compressor manufacturer specific PAG
oils.

The compressor comes with a full charge of
oil for the entire refrigerant circuit. However
The amount of PAG oil supplied with the
replacement compressor may not be the
exact amount required to replenish the
refrigerant circuit. Drain and measure the
PAG oil in the replacement compressor to
determine the required amount. If the
amount needs to be adjusted, do so using
the correct type of PAG oil specified in
ETKA. Refer to Elsa for the correct oil
capacity for the compressor being installed.
