I cannot find this part listed anywhere. I was wondering if someone could tell me what it is. It is located on the drivers side near the fender.

I am currently starting the intake rebuild. This is a 1991 928 S4 (Automatic).

Thanks

 

It looks like the push on connector housing the connections for the ABS and brake wear sensors??? SHould be located next to calliper. 928 612 531 01 ( LHS) 928 612 531 00 (RHS)

 

You need to look a little harder:

 

Of course, knowing that it is where the brake pad wear sensor and the ABS speed sensor comes through would help a bit....
