Hey everyone,
I planned on purchasing the OEM tow bar for my 2012 Q7 but have been hesitant since I can't find the coding to make everything work once installed. I found a few things from other forums but am not sure. Has anyone here installed a the tow bar and have a successful source to OBDeleven specific coding? Many thanks in advance.

Old post... But I thought I would give a reply.
I would suggest getting a Towing Module & Harness off eBay and plugging that into the rear connector (right-side rear corner). This will automatically adjust the transmission shift points and boost the turn signals (indicated on the dash) when a trailer is plugged in. I used an after market tow hitch (very easy to install), and purchased the module after struggling to get the trailer connections to work properly.
