Mercedes executive director Toto Wolff has urged the FIA to rethink their position on the impending radio communications clampdown.
Formula One's governing body had initially banned all communications between the teams and their drivers relating to the performance of the car, but their original stance was since revised.
Now teams are only facing a radio ban relating to driver performance, with plans set to be enforced for the 2015 season.
The FIA feel that teams advising drivers on their performance breaches the sporting regulation, which states "the driver must drive the car alone and unaided".
However, Wolff has called for a rethink to their position in the wake of Nico Rosberg's situation in the Singapore Grand Prix, when the German's steering wheel became faulty during a lap.
Wolff said: "We had several moments where we discussed whether what we were saying was still within what is allowed, so I think there are some messages that will require more calibration.
"If it [the clampdown] had been enforced as originally suggested, it would have been a nightmare.
"Can you imagine not being able to give any messages to the drivers in our situation [regarding Rosberg]?
"How do you want to communicate with the driver whose steering wheel is not showing him anything anymore? It's also a matter of safety.
"Maybe the Singapore race, with all of its ingredients, needs to flow into any future decisions on radio messages.
"I think Charlie [Whiting] and the FIA have realised that this needs another look, and I'm sure that good will come out of it at the end."
