Hi again, Tomsol.
Yes, I understand that Remco as well as many well-meaning posters here on the forum will always say "check your owner's manual" as a standard response. Again, and I'm sure it's obvious, if a manufacturer does not officially address the "flat-towing behind a recreational vehicle" issue in their owner's manual, then that vehicle will not be listed in either of the well-known dinghy towing guides that are published annually (FMCA and Motorhome Magazine). Volkswagen has never officially endorsed flat-towing behind a recreational vehicle so their owner's manuals will not give specific flat-towing instructions for that purpose and, again, none of their vehicles have ever been listed in the dinghy towing guides.
I've written to VW twice about the towing issue as I at one time wanted to tow a Jetta TDI. The first time I wrote, they gave me a "no" as I think they misunderstood my question and thought I was talking about their dual-clutch manual automatic transmission. I wrote again after another poster posted their response from VW and did get a "positive" response that both their FWD 5 and 6-speed manuals are flat-towable.
Here is that other poster's (ranchgal) response from VW ...

I received a similar response the second time I wrote.
However, the last reply in that thread gives another response from VW and actually does say to consult the owner's manual pertaining to towing and disabling the KESSY system (VW's keyless entry and ignition system). I don't think they had KESSY in 2002 so I don't believe it's something you have to worry about.
BFlinn181's response in that thread gives some guidance on how to tow as he stated that he tows a 2000 TDI Beetle. Hopefully, he'll chime in to this thread and give you further guidance and maybe answer more of your questions.
Have fun towing your Cabriolet and safe travels always!
