This was originally posted on rennlist but never received any replies so I thought I'd try mu luck here.


I picked up a Draw-Tite hitch for my 2011 CS during the 20% eBay coupon sale the other day as the price was just too good. I likely won't need a controller right away but in looking at which controller would be needed it is, needless to say, a bit confusing as to which will work.

What I'm seeing is the current version is 7P0-907-383-G. It appears the the original version that came with the MY11 is 7P0-907-383-B and there seems to also be the 7P0-907-383-F for the VW/Audi variants. There are quite a few of the B/F versions available used. I know the G version will work but will either the B or F versions also work w/o any issues? I've looked around a bit but can't find any place that documents what the changes are between the various revisions.
