Question: Should the EGT probe be placed in the manifold or
the turbo housing itself? I've gotten conflicting answers to this question. I have also checked the archives to also find conflicting answers. Can someone help me with this? TIA Mike

Covered a few days ago, but...
I think if we're talking about a K03 or K04, it should go in the turbine housing of the turbo. One of the main reasons for the EGT gauge on this application is to tend to the needs of your turbo. Too much heat can kill the turbo.
I can't figure out how to dredge the days-old discussion out of the archives. Help, anyone? (It could have been in the A4 forum, maybe?)

Info..
The ideal place for the probe would be between the turbo and the manifold just below that junction. That is where you will get the proper reading.
Most of us choose to place the probe just after the exhaust turbine wheel. If you place it before and the tip melts off= bye bye turbo.......

Then you are saying it should go . . .
after the turbo. Is the pipe just after the turbo the actual exhaust or the down pipe? I have not crawled under the car and will be replacing my exhaust with a 3" one on my TT and wanted to install an EGT while down there. So where exaclty am I looking to tap into? Which pipe?
Thanks.
Thanks.

Just after the exhaust turbine in the turbo housing..
You want to get as close as you can to the turbo other wise it will read a bit low. When exhaust is forced through the small opening in the turbo is compressed. Hence, its hotter.. Todd at AWE mentioned that that would be a safe place. The ideal place would be before the turbine in the turbo housing. If the tip of the probe gets to hot and melts off it will destroy the turbo.

What is more important to know, what the temp inside the turbo is or what the temp of
the internal combustion is? Can you not monitor the temps of the turbo by first getting readings of internal combustion?
