Vagadia joined Senvion from Suzlon, where he had been group head of finance, in December. He replaced Marcus Wassenberg, who had been Senvion CFO since June 2012.
According to Senvion a new CFO will be announced "in due course".
It was the second time in three years a senior Suzlon executive had been brought in to take on a board-level Senvion role. In May 2012, Vinod Tanti, brother of Suzlon group chairman Tulsi Tanti, started a year-long stint as chief operating officer.
Last month, Suzlon agreed to sell Senvion to private equity group Centerbridge Partners in a €1 billion cash deal.
Suzlon acquired Senvion, or Repower as it was then known, in 2007 after a four-month battle with Areva. It acquired 60% of the company, which rose to 92% in 2009 and 100% in 2011.
The original Suzlon-Senvion deal in 2007 valued the company at €1.22 billion.
The relationship between Suzlon and Senvion has never been a straightforward one. Under German law, Senvion's IP was locked down until Suzlon acquired over 95% of the company, while Senvions's banking arrangements have made it difficult for Suzlon to unlock any capital from its subsidiary.
