Berlin / Wolfsburg (dpa) - Volkswagen has built in its own account in newer diesel cars not inadmissible shutdown devices for manipulating the exhaust emissions.

According to the current state, "nothing illegal happened," said a VW spokesman for the German Press Agency. He responded to a report by the SWR, according to which even in newer diesel engines with the Euro 6 emission standard, a software is installed, which recognizes whether the vehicle is on a test bench, a so-called "cycle detection". Specifically, it is the SWR report to the successor of the scandal engine EA189, EA288.

A VW spokesman explained that it was not forbidden to set so-called "driving curves". Certain characteristics of a car are adjusted in such a way that in principle it can also be recognized whether it is currently in a test bench test. However, these settings should not be used by developers to influence exhaust control, for example. There are no indications that such a thing could have happened.

Also on SWR demand, the VW group denied the charge: vehicles with the diesel engine EA288 contained "no cycle detection" and therefore no inadmissible defeat device.

Already in the fall of 2015 shortly after the announcement of the VW exhaust emissions scandal with the engine EA189 in the center, the suspicion arose that even the newer unit EA288 could be affected by manipulation. Even then came VW "after thorough examination" to the conclusion that in both EA288 variants - with Euro 6 and the earlier emission standard Euro 5 - "no software is installed, which constitutes an inadmissible defeat device in the sense of legislation". The SWR now relies on internal VW documents from the end of 2015, which describe in detail how a "cycle detection" works in the EA288.

When four years ago in the US revealed exhaust affair, which has already cost the VW Group many billions of euros, it is purely technically that a VW software detects that the car is tested on exhaust gas test stands. The settings are then changed so that the guideline values ​​are reached. Outside on the street in everyday life, the values ​​are higher, and the data from the laboratory situation are clearly exceeded.
