hi guys,
while changing the oxygen sensors on the banks of my 2.8L A4, I broke the nipple off of the EGR valve on the passenger side. Anyone have a spare passenger side EGR valve they can send my way?

I found from ECS tuning that the part numbers for it show as either 078131102N or 078131102L:

I found one on ebay with the part number 078131102F. http://cgi.ebay.com/ebaymotors/PASSA...#ht_2050wt_939

Does the letter at the end of the part number mean anything?

Thanks for the help! Happy new year!
