Peter Sauber has denied rumours the disqualification of the C30 cars in Australia cost technical director James Key his job.
Briton Key, who has been with the Swiss team only a year after switching from Force India, is ultimately responsible for the 3-5 millimetre rear wing breach that cost Kamui Kobayashi and Sergio Perez their points in Melbourne.
Reports said the mistake, the result of poor construction quality control, could cost Sauber millions and 39-year-old Key his job.
The speculation stepped up further when, while the rest of the race team has stayed in Asia before Malaysia, team boss Sauber and Key returned to Hinwil.
"For me, the wounds are definitely far from being healed," the gutted Sauber told the Swiss newspaper Blick.
But I will send a clear message - there will be no dismissals
Asked if there will be consequences for those responsible, he said: "I don't want to say anything about that.
"But I will send a clear message -- there will be no dismissals."
Last year, Sauber ousted Pedro de la Rosa after Monza, so he was asked if a similar course of action would not be appropriate now for Key.
"They are two separate cases," said the 67-year-old.
At Hinwil, Sauber is busily constructing new upper rear wing elements that will be transported to Malaysia in hand luggage.
