Eh! This is driving me nuts. Arthur had an easier time drawing Excalibur out of the Stone than I'm having pulling this sensor.

I've spent an entire day spraying a very aggressive penetrating fluid onto the sensor, giving it an hour, pulling and twisting and repeating the whole process. No success whatsover. It will easily twist and turn its way up to the o ring and no further. At one point I even tried to pull it up by hooking a pry bar under the exposed body and using it like a slide hammer. Made absolutely no difference.

It's obvious to me that I'm having to use wayyyyy more force than a Porsche technician woud expect to use. I suspect that the support bracket hole hasn't been machined out to spec. It REALLY shouldn't be so tight that I have to remove the whole bracket in order to hammer it oput with a mallet again.

A whole day fiddling around with a serviceable item just isn't on - I could have unbolted the bracket and refitted it in an hour or so. I've decided to pull it tomorrow and then have the whole bracket machined out so that the o rings on the sensor barely touches the metal.

I'll gap it using a depth gauge - gluing washers / fitting / removing / refitting is just too much like buggering about.

Thanks to all who took the trouble to post ideas though.
