Grinding Noise Turning Left

ThatRWD · 08-29-2014, 04:41 PM

I've got kw v3 and have the noise issue, what did you have before?

'Shudder' at low speeds while turning came back shortly after getting my car back from the dealer.

Just lived with it for several months.

Changed the tires, now shudder gone.

It was uneven tire wear - inside edges of both front tires were worn significantly - not sure why. Replaced the Continental ProContact RFTs with Bridgestone Potenza RE960AS Pole Position RFTs.

So what came of this? I just discovered this gem on my '11 335d

Bumping this thread. OP has exactly explained a problem I am getting. under light throttle turning left I get a rumbling groaning noise. It isn't the oil cooler vent either. seems to be many opinions but no actual cure. Any sort this out?

Mine sounds like a wire brush rubbing something anytime I turn the wheel at low speed in either direction. I also hear it a little as i drive slowly (straight ahead) over speed bumps.

I recently changed to Koni FSD golds and had both control arms changed on my 2008 e90 335xi

I reversed my car all the way to left/got out and saw that front right wheel was rubbing against the Oil Cooler Vent.

Hello All,
I thought I'd bump this thread as I am still having the same issue as OP. My situation at least hints at where the issue could be. I never experienced this before, then I had an aftermarket front mounted inter-cooler and turbo inlets installed at the same time. First time I took the car out I noticed a strange noise/slight vibration when accelerating during a left turn. It's only during left turns and it has to be at a specific angle during throttle. I've learned to try and not accelerate during left turns. Whatever it is, it's definitely turbo related. I hear my turbo struggling for air (not sure if its going in or out) during these conditions. There is also a very slight vibration happening at the same time.

I've brought it to the shop that installed the aftermarket parts and BMW. Neither can figure out where the noise is coming from.

Any ideas?

All too often issues are asked about here in the forums and the possible fixes never make it back into the thread for others to learn from so I thought I would post something here on this topic.

I had this very same issue with my '06 330xi. Mostly when turning left but also sometimes turning right at slow speeds. I suspected it was something in the drive train because I could almost feel it through the stick shift. I did some more digging and found out that the issue seems to be linked to the AWD system because it was being reported by X3 drivers as well with some saying it was the transfer case itself.

I didn't quite understand how turning at slow speed would affect the transfer case but I did read that as a first step, many people recommended changing the transfer case fluid. I finally did so (not an easy process on the 330xi) about 3 weeks ago and the grinding noise is now completely gone.

It's a low cost thing to try first before you start digging into other drive train or suspension components.
