Be careful!! The larger 1/2" bolts at the bottom, that are referenced as temporary, or may rattle, are in fact permanent and should be torqued to 75 ft-lbs according the manufacture's instructions.
Thanks for the tip, we appreciate it! We don't post the hardware torque values, as they can change over time. We recommend folks check the install instructions for the latest and most accurate torque ratings. www.etrailer.com/Trailer-Hitch/EcoHitch/306-X7332.html
Good question, it's also a question we don't have a straight answer for. The owner's manual states that the vehicle isn't intended to be used for towing. We found other references online that stated the vehicle has a 1500 kg towing capacity. You might want to contact your VW dealer for clarification. www.etrailer.com/Trailer-Hitch/EcoHitch/306-X7332.html
