Hi i have a TT roadster 2008 and have a problem with the roof not closing. I have had it checked and the faults that come up are 2000 switch setting implausible signal sporadic , 3247 convertible top sender , right g597 implausible signal sporadic , 446 function restriction due to under voltage lower limit not achieved sporadic. I would like to know the meaning of these codes , if it is possible to sort this problem out myself and how would i go about it or do i have to take it to a dealer to get it fixed as a have a son that is a mechanic .but not an audi mechanic so does not have a lot of experience with problematic roofs.
