Germany BGH Remands BMW Diesel Defeat Device Case VIa ZR 957/22 for Difference-Damage Assessment

In April 2026 Germany’s Federal Court of Justice remanded a BMW diesel defeat‑device case (VIa ZR 957/22), confirming that buyers can pursue difference-in-value damages under EG-FGV and Euro 5/6 emissions law even where intentional immoral conduct is rejected. This ruling adds to a growing line of BGH diesel judgments, signalling sustained civil liability risk for manufacturers whose Euro 5/6 vehicles contain unlawful emission-control strategies long after the original sale.
