If the manufacturer, with their vast resources, can't fix the problems they've built in why would you expect a dealer based technician to be able to? All of these problems are being, trying to be fixed, directly in conjunction with Skoda Technical so perhaps it would be more accurate to say Skoda can't fix their own cars and are leaving the dealers to pick up the pieces. Dealer's in these instances will simply be following guided test plans and relaying back their findings in ongoing dialogue until the problem is fixed or Skoda run out of ideas. The other factor to realise is that dealer level diagnostic equipment only has certain levels of access whereas the manufacturer has total access.
