Hello all
İ am new for this forum and have a problem with my 2021 c5 ac 1.6 180hp. 80.000 km old
Problem: sound coming while driving sport style at high rpm . Sound starts with about 5000rpm.
Following link you can find and listen noise.
I believe that it starts after changing pcv valve (which has giving noise 1 month ago).
Dealer says its normal since it is powerfull car bla bla.
Is there anyone can help about that issue.
P.s: for me it is not turbo sound, it is like problematic pcv valve noise.
Ps2: no noise when driving relax even at 5000 rpm
