Hello,

I recently bought a 2000 Fabia 1.4 MPI 50kW with AC for my father. The car was neglected for a long time by the previous owner, but fortunately, it is rust-free (everything else I can fix myself, potentially).

.

There are a couple of issues that are high on the list for fixing, and for me, the most annoying is this whistle that is present the whole time when the engine is running. While you keep the throttle almost at full, it goes away, but in any other case, the noise is there, and it's driving me nuts.

Firstly, I thought that it's a vacuum hose that goes from the brake booster to the inlet manifold (the hose was already "fixed" by the previous owner with duct tape), but even after that replacement, the noise is still there. Any ideas what it could be?

P.S. This was recorded with my phone that was 5 - 10cm away from the throttle pedal. I wanted to upload the whole clip, but it exceeds the file limit.

Thanks!

Cant hear the noise from your clip but my hearing is a bit shot. Wondering if its the brake servo vaccum unit itself thats leaking rather than the hoses. Its the only thing I can think of that would make a noise near pedals.

Yeah, brake servo is the main suspect now, especially since the noise disappears when you fully press a brake pedal.

Might be the seal where the servo pipe joins it.

Just to finish this thread. I did replace the brake booster with a second hand unit (same part number), and the noise is gone.
