What's this sound (video included)?

Just noticed this the other day. I can hardly hear it inside the vehicle with the windows up and only noticed it when I was driving between the drivethru speaker and window at a local Tim Horton's. Any ideas? Sounds serious.

And is this a normal amount of play in a drive shaft?

Not sure about that noise, but your front driveshaft looks good to me. (It doesn't look like the play is in the u-joints, but is instead gear backlash).

Is gear backlash a good thing?

The only play is in turning the shaft...so I was thinking the same thing in that the u joints seem fine and intact.

Yes, it is a good thing. It is basically some freeplay built into the differential so that it does not bind up. I have the same movement on both my 4wd vehicles.

Play in the u-joints (one on each side of the driveshaft) would be bad, but after seeing your video they don't look loose visually.

Phew. Was looking at drive shaft prices and was starting to sweat. Hopefully the "ting" isnt anything serious. Was going to try toggling first and second gear next time I hear it to see if it is transmission related.

Was also afraid of catastrophic horror stories of driveshaft failures. Is there another drive shaft I should be checking?

Yes, there is a rear driveshaft as well (although it is a little more difficult to access). I had to replace mine, but my symptoms were different. My rear u-joint was seized, and the center bearing had a lot of play. It vibrated the car (especially at highway speeds), and there was a distinct 'clunk' when shifting into reverse.

It you want to check it, you will need to remove a few bolts from the aluminum underbody heat shielding. You can reach it without totally removing it as well.

Can you tell where about the 'ting' noise is coming from?

Sounds like right under the oil pan area, but it is really hard to tell. I havent experienced any drivabikity issues. I do occassionally hear the same sounding ting when shifting from P or N to D but not all the time.

Likely unrelated but almos tthe same day I noticed the ting sound, I also had a CEL and rough idle that I have yet to diagnose. I relaize it is 99.9% likely to be unrelated but just thought I would throw it out there. The ting noise is rotational... I.e. it varies with the speed of the car.

Okay, seems like it would be worth checking the rear driveshaft then. Mine was shifting from P -> R, D -> R, or N -> R, but never when going into drive.

Finding the culprit of your CEL could lead you to find the problem, but its hard to know for sure. See if you can get the code read (BMW INPA on PC, or Autozone)

I'll include some photos from when I changed my rear driveshaft (although it probably won't be of much help). Take a good look at the rear u-joint - mine was completely corroded due to road salt/water.

Hope you got a Dark Roast, they have a promotion now any size for $1, as long as its Dark Roast

Is it only when moving? Almost sounds like the stuff that holds the brakes pads/rotors rattling a bit. If its the metallic noise you were talking about?

Driveline lash and play is normal.

Only when moving. The sound happens faster when goong faster, slower when going slower - corresponding to the speed of the vehicle. Only notice it at low speeds.

Codes it is throwing is 2882 and 2883. Checked the intake boot, replaced air filter, cleaned MAF, DISA and ivc with no impact on codes or rough idle.

And yes - only dark roast. Must be a US $1 promo... Still regular price up this way. But I did win a cookie on my roll up the rim lol.

Oh it's CDN, $1 over here on the East Coast! Got a few other coupons too lol just came in the mail couple of days ago.

Perhaps your CV axles? Only a few things that are rotational and get affected by speed that would make metallic noise like that.

Ie.. I got my X3 back on Nov 2016, for the first couple of months ever time after I'd drive and stop, reverse I'd hear this clanking noise. I assumed worst checked things down there all tight. Fast forward to a day in the garage I was poking around in the battery tray area and noticed that the part of carpet that's right against the seat and rear has a void of sorts.. after looking closer I see stuff in there so I start to remove that part of the floor to get my hands in. What do I find? The POs kids I'm assuming somehow dropped those kinder egg shells on there and those would roll around and make a metallic sound yet they were plastic, once I pulled 5 of them out no sound was heard ever again..

Seems like you are on the right track with the lean codes. Normally would be one of those items. One other quick thing to check, on the back of the intake manifold there are 2 little rubber caps. Mine had cracked to the point they were leaking (not enough to throw a code, but could notice difference in INPA). I am almost wondering fuel filter in your case - that would explain driveability issues.

How many miles on your BMW?

Just had an indie diagnosing the problem. Rough idle was oil seperator / cvv and the clinking sound was just a loose heat shield. Who knew. Still the cvv os a nice dent to the wallet.

Great! I am glad you found the problem. CCV are a common failure on these cars.

The vacuum caps are on the back of the intake manifold, also right behind the intake tube. Tough to see without a mirror, and can't be reached easily with the tube on.
