Phaedra, it's a low-pass filter, i.e. it does not allow extremely rapid
changes in the signal from the AFM to the ECU.  It was made to correct a
bizarre situation where the AFM would go into mechanical oscillation and
confuse the ECU, but it also traps spikes from a worn-out AFM.  Along with
cleaning and maybe relocating the carbon track in the AFM, can eke out a
lot more life from a tired AFM.  A cheaper way to accomplish the same thing
is to wire a 22Uf 25V tantalum capacitor across the signal leads of the
AFM.  The VW cable is easy, but expensive.
