Hello Everyone,
ABS light came on and speedometer doesn't work at all so is vag-com scanned my 2003 A4 1.8T avant which came back with the following fault:

00283 - Front Left ABS Wheel Speed Sensor (G47)
30-00 - Open or Short to B+

I removed and cleaned the front driver's side speed sensor and put it back but to no avail. I ordered replacement sensor which I'm planning on installing this weekend but while removing the sensor I managed to break the screw which snapped at it's head meaning most of the bolt remains in the hub. Anyone knows what kind of thread it is and how to remove it? I'm thinking drilling through with a small bit hoping to get the bole out without breaking the thread.

Any suggestions will be highly appreciated.
