electrical connector, resistance reading, thread size and shape etc all identical, a direct fit for a Porsche supplied one.
on the 6 sides of this new one are
VDO
130 degrees max
is just blank with nothing on it

and an even more useful use of the sensor is as a waterproof, direct replacement for the HAVAC outside temp sensor in the alternator ducting.
just need a generic 2 pin connector on it as pictured, same as a fuel injector connector.
bottom picture looks like the multi meter probes are touching together, they are not.
and as the readings show it goes get hot in the UK, sometimes
hopefully will help someone in the future.
cheers
