Did Renault cheat on their ‘dirty’ diesels as well?

Today police raided Renault headquarters and a number of technical offices, wanting to check equipment that might have been designed to cheat diesel emissions tests similar to what VW did.

Renault said that the there was no evidence of anything of the sort but said that it was cooperating fully with the investigations.

The French stock market reacted badly to the news with the Renault share price diving 20 percent before bouncing back to just 10 percent down.

The car industry has been under suspicion in recent months following revelations that Volkswagen created systems that deliberately skewed emissions tests. It remains to be seen whether any of this will lead to any actual problems, but if it does it will be a huge embarrassment for the French government, which owns a significant share of the company.
