Late model VW A/C Compressor Shut Off Codes
Applies to: 2004 > Touareg, Phaeton; 2006 > Passat, Jetta, GTI; 2007 Rabbit, EOS
If for any reason the A/C compressor is shut off by the control head, MVB code may be triggered. Check MVB 13 field 1 for Touareg and Phaeton systems and MVB 1 field 1 for all other vehicles listed (including 2006 and later Climatic systems). Explanations of the cut off codes are listed below.
A/C cut-off Codes
0 = Compressor on (no shut-off requirement of the A/C compressor detected)
1 = Compressor off (refrigerant pressure was or is too high)
2 = Compressor off (blower motor circuit)
3 = Compressor off (refrigerant pressure was or is too low)
4 = Compressor off (display not currently intended)
5 = Compressor off (no engine start or no engine speed detected)
6 = Compressor off (A/C system switched off, ECON-mode activated)
7 = Compressor off (A/C system switched off, blower switch in position 0)
8 = Compressor off (outside temperature was less than 1.5°C and is still less than 2.5 °C)
9 = Compressor off (display not currently intended)
10 = Compressor off (Low voltage)
11 = Compressor off (display not currently intended)
12 = Compressor off (shut-off request from Engine Control Module (ECM) via CAN)
13 = Compressor off (voltage supply terminal 30 too high)
14 = Compressor off (Evaporator Temperature)
15 = Compressor off (display not currently intended)
16 = Compressor off (activation A/C Compressor Regulator Valve -N280- implausible)
17 = Compressor off (no signal or implausible signal from High Pressure Sensor -G65-)
18 = Compressor off (engine speed too high at standstill)
19 = Compressor off (shutoff request from Vehicle Electrical System Control Module via CAN)
20 = Compressor off (refrigerant loss-currently V8 Touareg only)
21 = Compressor off (Outside Temp < 2 degrees C, without recirc mode on)
22 = Compressor off (Outside Temp < 2 degrees C, Inside Temp. < 10 degrees C)
