Transaction No.: 2070041/1
Customer statement / workshop findings
Customer statement
Customer reports a red engine coolant overheat warning within the DIP
Workshop findings
One or a combination of the following DTC’s are evident within the engine control unit:
•
P218100 - Malfunction in cooling system
•
P017B00 - Cylinder head temperature sensor implausible signal
•
P017C00 - Cylinder head temperature sensor short circuit to ground
•
P017E00 - Cylinder head temperature sensor open circuit/loose contact
Technical background
The plastic housing of the coolant temperature sensor G407 may not be correctly sealed against coolant vapour therefore damage to the O-ring
located at the tip of the sender may allow moisture to enter the sensor element and restrict the function of the component
Note: The restrictions in some cases may be temporary
In the event the issue is as described the operative should refer to the instructions within the Measure section of this TPI
Production change
-
Measure
1) Referring to Rep.Gr 19 Coolant temperature sensor (V8 biturbo) - Remove G407
•
Check if the O-ring located directly at the tip of the coolant temperature sender (Figure 1) is visibly damaged/pinched
Figure 1
•
In the event the O-ring is damaged / pinched replace G407 including O-ring
2) In the event that no issues are found with the O-ring - Refer to the applicable circuit diagram, conduct an electrical integrity check of the
applicable circuit
•
In the event the wiring circuit and connections are to specification and one or a combination of the DTC’s remains please replace G407
including the O-ring as per Rep.Gr 19
