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.

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 Then I called my local audi dealership and they said the 058-906-283-C has been superceded by the 058-906-283-F. Does that sound right to anyone?

my buddy's 2002 GTi uses the F valve. FWIW

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My dealership guy told me the C has been superceded by the F. I don't know anythink else about the H,J, or K.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

how'd you gather the resistances of the coils?

Yup...my car shipped with "C"...in etka it is superceeded by "F".

I have a "J" ready to go in...

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