At the same time a survey of German dealers by Automobilwoche showed that sales of the new Golf are below their expectations.
Only be 115,000 new Golfs are likely to be manufactured in 2003 instead of the planned 135,000 units.
"That has nothing to do with low demand," a Volkswagen spokesman told Automobilwoche.
"We are focusing on quality rather than quantity and are therefore deliberately running a slower start-up phase for the Golf V."
However, Klaus Volkert, head of the general VW works council, told Automobilwoche that VW sales are "currently slow, unfortunately also for the new Golf."
VW bosses have not yet taken up an option of taking "special Golf measures" to boost Golf production in the first quarter of 2004. These include adding Saturday shifts.
"We will start negotiations about that in mid January at the earliest," said Volkert. "We are hoping for a sales rise during spring."
A poll by Automobilwoche of over 50 VW dealers in Germany showed there are clear indications that the new Golf is not selling well.
Most of the dealers questioned said that sales of the new Golf are below their expectations and worse than those of its predecessor.
