Overview
- The TÜV association urges stricter German inspection protocols targeting Euro‑5 diesels and certain early Euro‑6 gasoline direct‑injection cars lacking modern particle filters.
- Proposals under discussion include adding nitrogen‑oxide measurements for Euro‑5 diesels and expanding particle‑number testing to older diesel and gasoline vehicles.
- Around 16 million vehicles in Germany could fall under tighter checks, and a separate idea would require annual inspections for cars and vans older than ten years.
- ADAC and motor‑trade groups question feasibility, citing limited measuring equipment, uncertain applicability of methods to older type approvals, and legal risks.
- A Schleswig‑Holstein court ruling against “thermofenster” software heightens pressure for manufacturer‑funded retrofits, though the judgment is not final and Volkswagen plans an appeal.
