Hi, I'm new to forum and hope someone can help with this, it's driving me nuts! Dealer has said it's normal engine noise, Direct Injector noise, oil gurgle... I don't think this high pitched ping, squeal, chirp or ticking sound is normal.

Thanks for any feed back.

All I heard on that video was normal DI injector noise. They are loud, which is why manufacturers put insulation over the injectors to try and limit the noise.

Hi, thanks! So the metallic high pitched noise at about the 50 second mark are the DI's?

In playing that video, I don't hear anything unusual, but then, your ears might be better than your smartphone's mic. Most phones don't record sound very well. Plus, the recording never dwelled at any one location for very long.

Finally, if you wanted a really quiet engine, ie: no valve noise, no injector noise, etc., another brand of car is probably a better choice, such as Cadillac, Lexus, MB and so forth.

That's what it sounded like to me over the internet.
