READ ANSWEREngine makes a sort of "eeerrrp" chirp sort of noise when I shut it off.
Monday 10/13/2025 | 2002 | Boxster | Engine
The noise lasts about a second just as I shut the engine off. I can't hear any noises when the engine is running. I took off serpentine belt and noise still occurs with the belt off so it's not a idler pulley, AC or alternator. There are no codes and no Check Engine light. Any ideas.

I get no particular joy unnecessarily burning fuel at a stop light, but I want this e ...
