Valeo bought 53 percent of Sylea in September last year as part of its takeover of the automotive activities of Labinal, a French aeronautic equipment company.
The move was part of Valeo's plan to boost profits by providing a greater proportion of complete electrical and electronic systems for its automaker customers rather than only individual parts.
Sylea's board approved the acquisition and eventual squeeze-out on Sept. 6, 2000. Last year, Sylea posted sales of 1.3 billion euros.
Valeo employed banks Merrill Lynch and Societe Generale to help it mop up the remaining stock.
