Hi there guys, I'm new to the s2000, just got my s2k back in July of 2020. A couple months after buying it, I noticed that when I tried to shift during high RPM, the clutch pedal would get stuck. I went to a shop to fix it right away, and they replaced my clutch master cylinder as well as the clutch reservoir, and they did a full flush. It was pretty good for a while, but now I'm hearing this weird "bubbling" sound from the close left side of my car during acceleration, and sometimes on deceleration (although its much quieter and it dissapates). It wasn't that much of an issue, cause I could still drive it around, and it didn't mess up my shifting or get stuck like before. I took it to a shop recently, and they said my clutch fluid looks fine, and they also said that during use of the clutch, it needs to equalize the pressure or something like that. I don't know if that dude was talking out of his butt, but I believed him because he's a mechanic and I'm not. Just today though, it got pretty loud, louder than before. Any ideas what it could be? The sound is sort of a low pitch bubbling/rumbling sound, and its very close to the driver side, so I think its the clutch reservoir, but I'm not sure. Any help would be greatly appreciated.

Is the fluid level in the reservoir dropping or staying the same?

I guarantee your clutch fluid is not bubbling.

snayl

It's staying the same

Any ideas what it could be then? Any help would be appreciated.

Can you make an audio clip of the noise?

snayl

Yea, I'll try to get an audio clip today.

Got my audio clip finally working. After listening to the recording I noticed its not really that "bubbling" sound I thought it was. The sounds are most apparent at 0:03 and 0:08-0:12. Again, any help would be greatly appreciated.

Almost sounds like the start of brake wear warning noise.

Oh I’ll check this out, thanks!
