I've had the sensors leak from both the electrical connectors and from a hairline
crack around the threads - the latter from overtighening when trying to re-use a
hardneded o-ring. If you can't find the crack, then it is mostly likely leaking through
the connector. Be sure to get a new o-ring with the sensor, and tighten gently. It is
the same one as used on A2 Golf/Jettas, so very common and cheap.
