Since 2016, Porsche has been working with Federal Motor Transport Authority (KBA) to update the engine control software for all diesel vehicles of EU6 emission class.
The company has updated more than 8,600 vehicles in Germany so far. Porsche said that they will shortly introduce another software update for Macan 3.0 V6 diesel vehicles. After KBA approval, a total of around 52,500 vehicles in Europe (14,000 in Germany) will be retrofitted with the new software. The owners will be contacted directly by their Porsche partners. The workshop visit, which is free of cost, will take place soon after an agreement and will take about an hour to complete.
As for the Cayenne 4.2 V8 diesel models, the approval is still pending with the KBA. This involves a total of around 7,000 vehicles in Europe.
Diesel engines traditionally play a minor role at Porsche. The company also said that they do not develop and build diesel engines on their own, but takes full responsibility towards its customers.
In future, Porsche aims to focus on a trio of further optimized gasoline engines, plug-in hybrids and purely battery-powered vehicles.
