Icemark gave this instruction in his how-to remove the 5&6th port valves:

4. Remove the oil metering pump rod from the front of the throttle body, it is held in by a small bobby pin, just get your pliers and pull it out, make sure you keep this for putting it back together.

I have a 1989 convertible. I can't find what he's talking about.

The rod is found on an S4 since their OMP is manual. An S5 OMP, on the other hand, is not mechanical and is controlled by the ECU, thus it would not have the rod.

 

Thats because you have a s5 with an electronic OMP, there is no metering rod on yours

 

Thanks guys

 

in your case it's just 2 simple electrical connections by the alternator.

 

Shhh...you're going to make it too easy!

 

he did not state which connectors though,or have a power point presentation on how to disconnect them..
So this may stump the OP..!

(J/K..!)

 

That's harsh, Styx.

But maybe not totally inaccurate. I'm totally confused by the multimeter.
