87 07 13Sept. 13, 2007
2015835 Supersedes T.B. Group 87 number 07-11 dated Aug, 28, 2007 due to
additional labor operation in warranty table.
Vehicle Information
Condition
A/C, No or Low Output
The cooling performance of the air conditioning is perceived as too low.
Tip:
Only vehicles with Denso air conditioning are affected.
Technical Background
The Evaporator Vent Temperature Sensor -G263- does not measure evaporator temperature in the air conditioning unit; as a result, the evaporator freezes over and air flow drops. The result is reduced cooling performance.
^ Old version of Evaporator Vent Temperature Sensor -G263- (lower
height)
^ New version of Evaporator Vent Temperature Sensor -G263- (greater
height
Production Solution
Modified Evaporator Vent Temperature Sensor -G263- with greater height
^ Passat: from 01/2007, Chassis No: 3C_7E149985
^ Passat: from 01/2007, Chassis No: 3C_7P118545
^ Rabbit, GTI: from 06/2007, Chassis No: 1K_8W008021
^ Eos: from 01/2007, Chassis No: 1F_7V032700
Service
Before replacing Evaporator Vent Temperature Sensor -G263- check cooling performance of the A/C system so that other causes can be ruled out.
Replace Evaporator Vent Temperature Sensor -G263- (1) for the evaporator. See Repair Manual Group 87 in ElsaWeb.
^ Park vehicle for a longer period until evaporator thaws. Symptoms should then disappear.
