I was wondering if anyone has encountered this issue.

I have a 958 CTT and when I floor the gas, hit the red line in 2 consecutive shifts and solw down, a bad smell coming from the exhaust makes its way into the cabin (even if I have the AC recycle button on).

I took the car to the dealer and complained multiple times and they mentioned that the issue was with the ventilation. The first few times they claimed to had fixed it but it still existed. The last time, they said they communicated with Germany on the issue and found a solution.

Unfortunately, a few days later the problem still existed and I do not know what to do as the smell is not your normal exahsut fumes (it smells like something rotten).

 

Not having this issue.

 

Went WOT several times and I think I have the same problem !

 

What did they fix during the previous visits??
