*** Update: KBA confirms manipulation at Subaru ***
Our law firm has succeeded in obtaining a (partially blackened) document from the Federal Motor Transport Authority. This is confirmed by the KBA "As can be seen from the justification there, the order is based on the Inadmissibility of the built-in disconnection device".
It is therefore certain that an illegal defeat device is installed in the 2.0 liter diesel vehicle. Subaru has already tried to fix this with an update - which led to major problems for most of our clients. Due to the problems that occurred with the update, Subaru (probably) decided to no longer offer it for the time being.
