WOLFSBURG—Volkswagen corporate and business communications head Andreas Lampersbach has become the latest casualty of the company's emissions scandal, stepping down after 14 years with the German automaker.

Lampersbach's departure follows the exit of his boss Stefan Grühsem last month. Grühsem was replaced by head of group communications, investor relations and external relations Hans-Gerd Bode, who followed CEO Matthias Müller over from Porsche.

Lampersbach is one of a wave of departures at VW, as the crisis over its emissions tests manipulation escalates. Volkswagen's design chief, Walter Maria de Silva, resigned last week, following ex-CEO Martin Winterkorn and US head Winfried Vahland out of the company.

Lampersbach's duties have been taken over in an interim capacity by spokesman Eric Felber. "This departure is a loss to our company," said Bode. "Over the last few weeks in particular, Andreas Lampersbach excelled in demonstrating his outstanding communication skills. During this critical period he showed wisdom and a sense of responsibility in his handling of communications for Volkswagen."

Lampersbach headed communications operations at the 'Expo 2000' world exhibition before moving in 2001 to join the Munich-based MAN Group, which became a subsidiary of Volkswagen in 2011. In April 2015 he relocated from his post as MAN Group's head of corporate communications to Volkswagen's group HQ, becoming head of corporate and business communications.
