Thread: 300TDi EGT probe position?

The info I found re EGTs, for probe placement after the turbo(as in the install in your situation) is about 200°C lower than that, or about 500-520°C.

I'll have to sift through a fair few bookmarks I've managed to accumulate, and if I find the source of the info I found a while back .. I'll link to it here again.
All I remember was that this guy had two probes running concurrently, one at the EGR plate, and one after the turbo(but can't recall exactly where after the turbo he had his second probe).
He had graphs with his recorded temps to show about a 200° difference.

Yea I've heard that too. ~200ish C difference from pre turbo manifold to post turbo dump pipe. I would move it to the blanking plate though as 720C is a documented number at that location where as post turbo is a bit of a guess as any number of things can give temperature differences different to the above and take you into the danger zone without you knowing.

Don't stress about it varying as you drive. Mine is up and down like a whores' drawers on a Friday night. The slightest change in throttle position or road conditions reflects almost instantly. (Mine is a digital gauge, probe in the egr plate).
