trailer hitch possibilities on s-line model
I know that if you order a A3 S-line directly with detachable trailer hitch then there will be a small kind of "flap" in the back which you can take out if using the trailer hitch.
How would it be done to install this detachable trailer hitch without the pre-made hole and flap in the back because there should of course not be a open hole if the hitch is not used.
Or is it only possible to install this with a new rear bumper which has the flap etc.
Thanks and Regards,
