Have a 2018 Porsche Cayman 718 and at around 1500rpm i can hear a beeping noise from the engine, its the same pitch every time but length can vary. Is this normal? Any ideas?

Some of us have heard it when revving up a cold engine. Do you still get it with a warm engine?

I have it sometimes (but not often) on cold startup especially when car hasn't been drivin a few day's. Had the dealership look into it but they found nothing and said it was ok. Now on 40000km without any problems. I have posted a soundclip and also another member who has/had it in the same circumstances like you describe posted a video. Here is the topic: GTS strange sound on startup

The strange thing is that no dealership around the world knows that there is a beeper back there somewhere...
