This would imply that it is an INTAKE temperature sensor not Exhaust. Known as the IAT sensor (Intake Air Temp) nothing to do with the exhaust temp. You need a Pyrometer for that preferably instlled pre-turbo. I had one in my 2000 Golf TDI and my 2004 Jetta PD TDI. Found it to be quite useless even with mods you have to be at full throttle for well over a minute to get anywhere near the danger zone. Was only good for shutting down engine I would wait until below 500*. Decided not to put one on the Passat TDI. Not worth the trouble IMO. Depends on how you drive and how hot it is in your area (and your mods, or if towing?)MOGolf said:The car already has thermocouple (known as turbocharger intake temperature sensor G507). It is located in the exhaust manifold between where the exhaust ports come together and where the turbo bolts on. VAG-COM displays the reading in ECM measuring blocks group 067 zone 1, though the latest (as of this writing) labels file do not label it.
Why is EGT so important? Curious...vw4life said:.... Does the computer reduce fueling or boost to protect itself?
I would not doubt it does
If I chip my car......Please do. Second gear is a friggen hoot w/ RC 2...
