03 — The case

The case against Opel

The DEJF alleges that Opel — under both its General Motors and PSA / Stellantis ownership — used defeat-device strategies in 1.6 and 2.0 CDTi diesel engines. The German Federal Motor Transport Authority (KBA) ordered a mandatory recall of certain Opel diesel models in 2018 because of impermissible emissions strategies.

The foundation served a writ of summons in 2023. The case is enrolled at the Amsterdam District Court and is currently in early procedural stages.
