Even though demand for Porsche diesels is falling, a fix was still needed for more than 38,000 Porsche Cayenne Diesel models affected by "Dieselgate". Porsche has finally reached agreements in the U.S. and Europe that will allow more than 38,000 3.0-litre V6 TDI vehicles with “Generation 2.1” and “Generation 2.2” engines to be brought into line with the emission standards according to which they were originally certified.

On Monday, the Volkswagen Group reached an important milestone in their negotiations with The Environmental Protection Agency (EPA) and the California Air Resources Board. Both agencies approved Porsche's proposed technical solution for adjusting emissions (the “Emission Compliant Repair”, or ECR) on affected Cayennes. As a result,eligible customers will be notified that they can receive the emissions compliant repair free of charge at their preferred authorized Porsche dealer beginning November 6.
The German Federal Motor Transport Authority (Kraftfahrtbundesamt – KBA) has approved the software update submitted by Porsche for the affected models. Porsche is now bringing the affected vehicles in to workshops for the free software update. Customers are expected to receive specific information from their respective Porsche partners from calendar week 45 and will be asked to schedule an appointment at a workshop. The software update takes about an hour at the workshop. If necessary, the Porsche Centre can provide a replacement vehicle for this period.
