Default part number question? N75 valve

I am wondering what the factory part number is for the N75 valve on a 1998.5 1.8T. I am not looking to get an upgraded value, just a stock replacement. I am hoping it will help with my surging (I have a Neuspeed chip). I have checked my 710 BVP and it is still good.

Default 034-906-283-C should be stock for your year, but test w/ohm meter.

before replacing. They either work or they don't. IIRC 20-30ohm is normal operating range.

I just read in another post that the 058-906-283-C is my stock value. Then I called my local audi dealership and they said the 058-906-283-C has been superceded by the 058-906-283-F. Does that sound right to anyone?

Default What I've found so far

So these are what I've found so far.
058-906-283-C 20-30 ohm
058-906-283-F 25-35 ohm
034-906-283-H 25-45 ohm
034-906-283-J 20-40 ohm
034-906-283-K 20-40 ohm

My dealership guy told me the C has been superceded by the F. I don't know anythink else about the H,J, or K.

This is my compliation of info from different sites

I got most of the resistances of the coils off a VWvortex post, I dont' remember where. The other one I got from SilverA4Fun.
