Probe. If you have a connector in line with the probe you might get lucky and find that is the problem - for that matter look over the probe wire itself to see if it has chaffed or otherwise damaged.

Hello all,
I recently noticed that the oil temp reading in our Extra became erratic and the indication is jumping between about 160°F and 200°F.
The high value seems to be at around the level I expect, while the low level is certainly too low. The needle in the temp gauge (Westach twin indicator for oil pressure and temp) is not moving slowly but jumping quite fast back and forth.
It seemed to be ok when I warmed up the oil on the ground before an oil-change, but in flight (with higher oil temps) the problem came back.
Has anyone seen something like this before and can give some recommendations to what we should look at? I´m suspecting the temp probe right now, but as the plane is more then an hour away from my home, I´d rather get as much suggestions from anyone experienced, before getting lost an endless "trial and error" hunt , chasing the issue.
Thanks,
Markus

Markus,
Good question, simple answer:
You have a loose and/or corroded connection.
You cannot inspect visually.. Remove the connections, clean them, replace the star lock washers with new. WHAT'S that you say... No, star lock washers? That's the other part of the problem.
Good Luck,
Barry
