Jay,

3437224015 is the old number, this current part has a 035 at the end. That will do it

I really would adjust the pot to voltage, but: chacun a son goût!

Reason is, the resistor is weared, that is why you change the pot. You can messure the Ohms of the installed one - but how can you be shure it's the correct value? My pot showed chaotic values at or near idle position, every small movement of the AMS plate forced the needle of the Ohm meter to swing...

In the early KE instructions (for M102 in the W201) Mercedes advised to check the Ohms, in the later docs (current CD or manuals) they advice to check the voltage. It should be 0.7V +- 0.25V - so why not set the new pot to the requiered value?

If you do so, you will realize, that smallest movements of the pot will lead to relativly large changes in voltage - I don't think that an adjustment to a mark will be sufficient.

The adjustment should be done by rotating the pot. Carefully screw it down so that you can move it by small hits of a screw driver...

Installation is not that difficult but you have to disconnect the fuel pressure regulator to get access to the lower right screw.

Older pots are fixed by philips (spelling?) screws, newer ones have torx T15. You will need good tools.

hope that helps,
bis denn,
Christian
