I have a panoramic sunroof. It failed to close a couple of times and was "fixed" under warranty.
now out of warranty it fails to open. It starts to tilt then sticks. The roof mechanism was cleaned and greased with "special Audi sunroof grease" last autumn. Is this a common problem or is my roof a bad 'un? To be honest, one should not expect annual garage bills to sort out a sunroof.
