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.
Re: 034-906-283-C should be stock for your year, but test w/ohm meter.
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 Then I called my local audi dealership and they said the 058-906-283-C has been superceded by the 058-906-283-F. Does that sound right to anyone?
