I hear a high pitched sound during releasing the gas pedal from acceleration (rolling mode)
It triggers usually during traffic 2-10kph with a hot weather, and then gets worse eventually if I use the brakes.
It goes away after 5-10 hours of resting the car and does not really trigger if there’s no traffic going on.
- Already replaced brake pads : did not wok
- Had checked Air vac and hoses were okay
- Replaced the engine and AC fans: did not work
It sounds like
- someone playing a flute instrument
- a siren
- Broken speaker/mic
