Thread: 300TDi EGT probe position?

Mine is here. It works fine. Not sure of the brand though, Maybe that is the problem. But everyone I have spoken to suggest that pre turbo is where you want it.

As per johntins' picture, most people fit the probe in the blanking plate and they survive just fine. It's highly unlikely that you've melted a probe, they are good for much more than what a 300TDi can do. However it could be a faulty probe, I had one that failed just after fitting and was replaced under warranty. They're not very dear in any case. Example:

Yep, the blanking plate is where mine is too.

Easiest location by a long way.
My only problem(dunno if others have/had the same), but the probe length was too long to fit once the probe was mounted on the plate and tryign to bolt the plate back up again.
So some gentle persuasion on the probe's heat element with a pair of pliers, curved to match the profile of manifold making sure that the inner probe didn't touch the cast iron.

Easier is to pilot drill the plate above the centre line then drill/tap at an angle so that the tip doesn't touch.

My plate was looking rusty and crappy, so my plan was to replace it.
Found one on fleabay probe bung ready, so the location of the probe bung was already setup by someone that didn't know how to account for various sized(ie. length) probes.

But, had my plate been less crappy looking .. and I'd got a blank requiring some of my elbow grease .. for sure I'd have planned it the way you describe.

I fitted mine (same brand as yours), as per johntins picture, however the EGT gauge only gave a reading for about four days, then stopped. The gauge still did it's little dance on start-up (Needles up to max then back to rest)
I contacted the supplier and was told there had been a dud batch of probes supplied to Australia and he immediately offered a replacement by mail.
That arrived two or three days later and the gauge has been operating perfectly since.
Don.

If i had installed the probe that indeed is where i would have put it.
but i have sent the gauge back to Melbourne and they tested it and found it fine and sent it
back with a new probe which it has been fitted with (current) the first probe was dead,
So what has been replaced is gauge, probe, wiring and it is still reading wrong thinking there is
wrong placement of the probe is all we can think of what would be stuffing up
