Ticking Noise Under Hood (Video)
What is this ticking noise(!?):

Just started hearing tonight!

In the second clip, it's there, increases in intensity, then stops, but returns...

I hear pretty normal injector clatter. In the first video I did hear what sounded like one injector acting up - but that would throw a soft code in the DME, so have your dealer check it out. These cars (for those who didn't know) have direct injection which means they have large, loud injectors that shoot gas directly into the cylinder, bypassing the intake manifold. Diesel cars use similar type of fuel delivery, so that's why there are some similarities in noise and why BMW put those large, thick sound dampeners on top of the motor.

Thanks for your prompt and thorough reply!

I'm not convinced it's normal, though, as it's the first time I'm hearing it.

Note it's persistent in the first clip, but only heard for a few moments in the second clip, after which you hear normal engine noise...

Sounds like a fan wobbling to me...

Mine does the same exact thing, u ever figure it out? Mine comes and goes too.

Mine as well. Maybe I'll have it checked out on my next oil change.

Itschase might be correct because the RR Ghost has a similar "ticking" sound upon start up.

Watch at 5:47 mark.

Just got mine back from dealer for the vibration issue under load around 40 mph and now I'm getting this ticking sound as heard in video #1 of original post. It had not made this sound previously and just started this today.

Has anyone had any insight on this fix?

Mine has this whining noise, does anyone else have this?

mrg0612 01-28-2014 03:40 PM

I previously had the whining noise and the fuel pump replacement fixed that.

DLF750 01-29-2014 05:35 AM

mine always does that ticking sound. I've been told by the dealer that it's a very loud car in terms of engine noise.

Sounds normal to me. Mine has pretty much same ticking, old and new engine alike.

PranavF01-there were a few complaints about this exact whine on the GT forum early on. The issue was the oil pump. At that time they were replaced under warranty. I would have your dealer diagnos it.
