German car maker BMW said on Friday it would recall 11,700 cars to fix their engine management software after it discovered that the wrong programming had been installed on its luxury 5- and 7-Series models.

“In the course of internal tests, the BMW Group has discovered that a correctly developed software update was mistakenly assigned to certain unsuitable model-versions,” the company said in a statement.

“The BMW Group informed the relevant authorities immediately.”

BMW issued the statement after a report in the Media suggested it had installed software that manipulated emissions of harmful gases such as nitrogen oxide, something its management has always denied.

Competitor Volkswagen reached a multi-billion-dollar U.S. settlement after admitting installing so-called “defeat devices” on its diesel models designed to game emissions tests.

VW has been roiled by the “Dieselgate” emissions scandal, which has forced it to set aside 25.8 billion euros (31.7 billion dollars) to cover fines and related costs, of which it has paid out nearly 20 billion euros.

BMW said the models affected were 5- and 7-Series cars made between 2012 and 2017 containing high-performance diesel engines and three turbo chargers.

BMW did not say where the cars were but said it would cooperate with the relevant authorities on further steps
