I bought a slightly used 2012 Golf TDI. I recently brought it in for the 10,000 mile service and the tech came back and asked me if I knew what had happened to the rear wiper and motor. I told him i had no idea, I had never really noticed it until he brought it to my attention. The wiper control on the steering wheel does have a rear control setting, and I can even spray wiper fluid! My question is, did the previous owner have the wiper and motor removed, or was this an option that wasn't included? AND, what do you think it would cost to have this installed? Thanks for your help!
