A friend's car is running up to 90 C or hotter fuel temperature. The fuel system is intended to maintain 70 degrees C.
The ambient temperature comparison test passed. All three sensors read the same. (fuel, IAT, coolant)
Replacing the fuel thermo Tee did not make any changes.
There is some indication in the Bentley (generic presentation of a PD overview,page 2-8) of a fuel cooling relay (J445) and fuel cooling pump V166. However I cannot find these components, either in the car or in the detailed section of the manual.
Searching the Bentley CD did not bring up any hits, either.
I have come to believe the components are not actually present on a 2004 PD BEW or a 2005 PD BEW, that perhaps they are on other models. UPDATE: I have confirmed they are not on our cars.
The thermo tee is supposed to send all fuel back to the tank once fuel temperature reaches 70 C and it looks as if it all goes to the fuel cooler under the passenger side of the car (without further manipulation by the phantasmagorical J445 or V166).
Can anyone shed any light on this benighted TDI brother?
