Better Flixtrain Door Sounds

The door sounds of the Flixtrain carriages are wrong and are from the IC carriages

 

That wouldn't be the first time. The Class 313 has the incorrect door sounds, and seemingly so do the TGV and Doppelstock.

 

Correct sounds already exist in TSW though - the n-Wagen have the same doors and sound right.

 

I just don't understand why they didn't use the n-Wagen door sound

 

doppelsctock is not bad

TGV doors sounds looks bad in TSW too
