Just wondering if anyone else has noticed the engine being overly noisey while idling, sitting in the cabin i can hear a distinct rattling/noisy tappet type sound, dealership couldn't find anything wrong.
Anyone elses like this, is it normal? I don't recall the N55 in my 1 series being like it.

Uhmmm maybe it should do that It is an exhaust, louder the better. I would be happy with it, if it is not something overly irritating with the whole car shaking or rattling.

Mind if you could record this with you phone?

It's not the exhaust, it's coming from the engine bay.

Will try and record something in the next day or two.

That is less cool if it is coming from there... Looking forward to the video.

ya, is kinda loud at idling, but if you idle for like more than 1 min,
it quite down completely

It doesn't sound too tappety to me, not compared to some of the fast nissans I had in the past but there is a little noise.

I was told by a Bmw tech that it was the direct injection system making the noise.

My wife's 328 also makes the same noises.

No. It seems really quiet to me.

Yes. I started getting something like a flywheel chatter at 600km. When I took delivery it had a beautiful tone. Now it sounds like a faint but noticeable marbles in a tin noise at idle. when the clutch engages it goes away. Its like someone is tapping at the middle of your forehead. Its not a very nice sound.

My car was an E92 N54 FBO running on E85. It had a beautiful tone and ran great.

The noise started when I had to keep the car a good acceleration into a major road. The engine was off due to auto stop, and then auto start kicked in, there was a loud metallic thud, and the noise what there ever since.

Is this what you are experiencing? Tell me more please.

Update:

The feedback from the BMW Australia Technical Head (who was at Westcoast BMW in WA Australia today): This transmission chatter noise is normal. Whilst page 148 of the manual says 'clattering' noises are normal on load changes, the response is that it also applies to the transmission noises on idle -- the noise in mine.

The noise characteristics of the demo car as compared to mine is the same, except mine is louder/ more pronounced. The demo car was beyond its first service at 2000km.

The feedback from the dealer is to monitor and check back again after first service at 2000km.

A little background:
My car: F10 523i no modifications. 2010-2011 model, done 44k Kms.
Not much used as it is a secondary option...so battery gets discharged.

At 40K kms, oil level sensor gave message "measurement inactive, have it checked". Dealer here replaced oil level sensor..Of course took a hefty amount but in vain.Said coils and DME is faulty and needs replacement but was not sure. The msg is still there and I ride with the orange light always ON.

At 44K kms, I started getting typically dry marbles like rattling noise from engine around the VANOS area above the tension belt.
Typically it starts with low rpm at below 1000 when idle.Above 1500, it seems gone.

Dealer said it "might" be...tensioner, idler pulley, timing chain setup, oil pressure or coils and DME. SO he is not sure and wants to replace it all.

I thought to check the oil level and oil filter, and no dipstick available. So manually drained oil to find 5 ltrs in the sump.

Forums say, its the tensioner and belt or idler pulley.

Can someone pl help?
