Can you guys listen to this 7 second clip (https://streamable.com/ri2j8k) and tell me if this sounds like the high pressure fuel injectors kicking on to you? I get this unusual noise on my W12 Bentayga. Almost sounds like the smoke monster from Lost, haha. The Bentley dealer just told me it's my high pressure fuel injectors. But this doesn't make sense to me because why would the *high pressure* injectors be turning on during idle? And this sound is also present 95% of the time while I'm driving and just cruising along with no heavy throttle demands from the engine. I would think the high pressure fuel injectors would only turn on when the engine demands more than normal fuel. So the dealership's explanation of this isn't checking with me. Wanted to get more feedback.
