Slightly different but similar to this noise - this was another forum members noise that was the same as I had for a long time. Mine was easily heard from inside the car. There are threads on the forum indicating it is the HBB motor (most issues on the Gen 3 section). I just had a new commutator put on my motor this week and put it all back together today.

I bled brakes today but will follow the process to bleed air from the HBB tomorrow as I have a vibration through the brake pedal when the HBB motor runs.

I am hoping that this is the end of the noise but it may take a few days to confirm as the noise was intermittent, but would occur once every 2 or 3 drives.

edit: our NS has done approx 294k kms.

Cheers,
James

James my noise occurs even when i am not on the brakes, the noise is more prevalent when motor cold, when motor hot it makes likes an exasperated high pitch noise again sounds like an air purge or similar

The HBB is an "accumulator" that pumps up to pressure then stops. Over time the pressure can "bleed down" whether the brakes are used or not, so the HBB will run at seemingly random intervals.

Don't discount the HBB.

just done some more research, might also be a faulty brake accumulator that is making the noise
