The carmaker, which is due to present to US authorities later in the day its plan to fix diesel cars affected by the scandal, has decided to cancel or postpone investments that aren't "absolutely necessary," Mueller said. That will reduce overall capital expenditure to 12 billion euros in 2016.
"What we definitely won't do is make cuts at the expense of our future," said Mueller.
"We're driving cautiously over the coming months, but we know where we want to go and we want to ensure that the Volkswagen company comes out of the current situation strengthened," he told reporters in a short statement, without taking questions, after the 20-member board met at company headquarters.
Volkswagen in September admitted that almost 500,000 of its four-cylinder diesel cars in the US had cheated on emissions tests thanks to a piece of software. A total of 11 million cars worldwide have the software, though it has not yet been confirmed that it helped cheat on emissions tests outside the US.

Volkswagen has a Friday deadline to submit a draft plan to fix four-cylinder diesels to the US Environmental Protection Agency and the California Air Resources Board, the two agencies that forced the German automaker to admit to the cheating. The company met with the agencies yesterday, with a final submission on Friday.
It will have two options to fix most of the cars. It can install a bigger exhaust system to trap harmful nitrogen oxide, or it can retrofit a chemical treatment process that cuts pollution.
Volkswagen's scandal has widened since the September revelations. The company also admitted finding irregularities in carbon dioxide emissions in 800,000 other vehicles, all outside the US. Some of those were powered by gasoline engines.
Carbon dioxide is a greenhouse gas blamed by scientists for global warming, and faces increasingly strict limits in Europe.
