another reason i got shot of mine...... i too had a loan car that had it - my GTi didnt, the standard sh!t did.
i asked the dealer and they said they would have to speak to VW as never seen it before - in fact, that was their default reply to most things.
The heated seat on passenger side stopped working - we'll have to speak to VW about that as never seen it before
Display often went blank or displayed "not available" - we'll have to speak to VW about that as never seen it before
The reverse camera didn't always open - we'll have to speak to VW about that as never seen it before
they then sent a customer satisfaction survey..... oh how i enjoyed filling that out - but they didn't reply which kinda sums it up really!
