The VW group owns Volkswagen, Audi, Porsche, SEAT, ...

If I remember correctly the Bosch cheating software was there for testing purposes but VW asked Bosch to leave it.

> Everyone else also uses it

No. Some companies optimize their engine to have optimal emissions in the exact conditions of the emissions test, but no other company has been found to have an actual digital switch modifying the engine's behavior only during the emissions test.

Oh my. Audi is the engineering part of VW, VW the low quality, mass market part of the brand. Engines are developed at Audi, they are the engineers after all, VW is a logistics and support company.

Porsche is the owner of the VW group. They bought most of the controlling stock.

Since everybody uses Bosch ECU's and most of the companies knew about this cheating low temp. switch in the ECU parametrization, it is no surprise that most of them have been caught using it. It is not illegal in Europe though, because laws are different here.

The only surprise is that media is ignoring it, and blaming VW who would be the last to blame.

Get yourself educated and watch the relevant CCC talk please.
