Continue the hunt for extended parameters here.
Thanks for the screenshot! I don't see an obvious mapping equation from the OBD value and the one on your dash, so we might need a few more data points to get a sense of the correlation between the two.
If you can get me two more similar screenshots of two different oil temperature values, I'll be able to plot the scaling function and we can update this to the right values 
I'll be tracking updates and resolution to this in https://github.com/OBDb/Seat-Leon/issues/20
