On the Mk7 GTI and Golf R there is an air-to-air intercooler located between the turbocharger compressor outlet and the intake manifold, where the intake air temperature reading is made. This discussion starts around 13:00 of the video. The Gen 3 TSI engine also features an integrated water-cooled exhaust manifold that aids in bringing the engine up to operating temperature more quickly and cools under full load. The engine should respond well to small changes in throttle inputs, with smooth part throttle performance around town and on the highway. thank you for all the research you have shared with us defiantly learning a lot! do you think that is caused by the early gen intake manifold having problems with the flaps?

I suspect the temperature reading from the IAT sensor is being effected by the location of the sensor inside the manifold. It then travels through the parts in green, including the Intercooler, and the air temperature is measured by the IAT sensor which is located just after the part shown in blue. I extended the IAT cable and moved the IAT to the plastic intake pipe about 8 away so it would actually read the air temp and not the water temp. Maybe it's not as audible as I thought in the video.

After the IC got through with cooling, the difference would be 1 degF. Heat soak in stop and go traffic has everything to do with the intake manifold heating up and the IAT sensor inside warming as a result. Has anyone tried moving the IAT to a location not affected by the surroundings and only reads the actual air temp? You can hear it, you can feel it,. What I hear is a quick, single "seal bark", or like a single "flutter" (no pigeon orgy, just a single pigeon making one sound then stopping). I assume the HT file has something to do with it.
