I'm back to my quest to get accurate oil temp readings. After reading numerous threads on VW forums I see that it is common that temp reading on cockpit instruments are not that accurate (meaning +-10 to 20F error). Some have resorted to trying different sensors until one a match between sensor and gauge is found.

The sensor I tried was this one, that nominally is a 0-150C sensor, but I understand matches with the 300F VDO vision gauge. However I didn't get accurate readings as mentioned below:

Part Reference Number: 049919563A 
Brand: FAE 

I was wondering if the newer style sender also has an M10x1 thread, and thus would fit my AAZ and other older Diesel blocks. This is the one:
https://www.busdepot.com/1h0919563
Part Reference Number: 1H0919563 
Brand: FAE (Italy) 

Also, maybe a long shot, what is the thread of a type 1 drain plug hole? If M10x1 could I try this sensor?

Thanks,

Interesting information. I'm pretty sure my sender is a VDO brand. I wonder how the accuracy compares to the FAE?
