Technical Service Bulletin
Technical Background
A failure of the sensor electronics causes a loss of pressure evaluation. The sensor with base part number
4M0959603 and a build date before the date Calendar Week 31, 2021 is at issue (G395 / G827).

Production Solution
An improved sensor has been implemented in production.

Service
1. Should the vehicle present with the symptom profile described in this TSB inspect and/or replace all of the
pressure sensors in the refrigerant circuit that are of the base part number 4M0959603 and have a build date
before Calendar Week 31, 2021. Each model for which this TSB appears will have between 1 and 3 of this
type of sensor installed at various positions in the refrigerant circuit, either on the low or high pressure sides
of the circuit (G395 / G827).
2. Inspect the markings on the sensor to
determine if the sensor has been previously
replaced with an improved sensor produced
after Calendar Week 31, 2021. Figure 1 shows
the locations of the markings and their
interpretation. In this example, while the sensor
is an ‘E’ index sensor, contains a green dot on
the connector housing and a laser marking on
the aluminum housing the build date of the
sensor is before Calendar Week 31, 2021, and
would require replacement.

Figure 1. Pressure and temperature sensor markings and
build date.
3. A sensor with index ‘E’, produced after Calendar Week 31, 2021, has a green dot on the connector housing,
and has a laser marking on the aluminum housing is of the improved type and need not be replaced.
