[s-cars] Re: Pulling Codes on S6

[Dave Forgie]

Ain't I good (actually, just lucky) to guess correctly!!  The CPS is just a Hall
Sender (i.e. a sophisticated magnet with wires).  It lives behind the intake cam
sprocket and therefore, to remove it you have to pull the sprocket which means,
at the very least, you need to slip the cam/timing belt off the sprocket, clamp
the belt so nothing moves and then pull the sprocket  off and change the CPS.
At worst, the exercise becomes a cam/timing belt change (c/w water pump, idler
pully, etc. etc.).  The CPS probably fails in the wiring, either  a bad plug
connection (clean and use Stabilant 22), or a break in the wiring between the
CPS plug and the magnet head (fixable) or a break right where the wire enters
into the magnetc enclosure (likely unfixable).  Try the PartsConnection or
Bimmerparts for lower pricing.  I think Bimmerparts had them recently for under
US$200.

Good luck.
