Felipe Massa has played down the furore surrounding the Mercedes drivers' latest crash, saying that what happened in Austria was just a "racing incident".
It is believed that Wolff will warn them of strict and clear consequences if they continue to tangle, although team orders have been avoided for now.
"We will present them with a new concept," team chairman Niki Lauda told Bild.
Marc Surer, a former F1 driver and now German-language TV pundit, said that Mercedes has taken the right decision.
"Yes," he told Germany's Sky. "Many people say Formula 1 is already boring because of Mercedes, so to introduce team orders would only have made it worse."
1996 world champion Damon Hill agrees, declaring that if Mercedes had brought down team orders, the drivers would probably have ignored them anyway and "fans would rebel against the idea".
Williams driver Massa, meanwhile, fails to see what all the fuss is about.
He told Brazil's Band News FM: "I think it was a racing incident.
"On the last lap, who wouldn't try to fight for position? It's totally normal.
"In my view it was a racing accident, but when it's with two drivers from the same team it causes a big problem."
The championship continues on Sunday with the British Grand Prix.
