Lately I've noticed a rattle when accelerating... wastegates? - BMW 3-Series (E90 E92) Forum

srcstc · 05-06-2010, 11:14 AM

Has anyone taken their's in for something similar? What was the outcome?

PhiDeltBeers · 05-06-2010, 11:16 AM

Rattle from the engine?

PhiDeltBeers · 05-06-2010, 11:17 AM

I had a bogging noise coming from the rear of the car under hard acceleration. Got my LPFP replaced and it disappeared.

Sounds like it's comming from somewhere under the car. Maybe the engine bay.

I have a small rattle in 1st and 2nd maybe......it quickly goes away though.

You guys experiencing any long cranks on startup?

I dont.

Curious about this one--can you go through various software upgrades, and the problem surfaces eventually due to mileage? Or does the software make it so this doesn't happen (at the expense of performance)?

Why does every thread turn into an HPFP thread?

Bakeme521 · 05-22-2010, 02:41 PM

I started a thread about this, I'm hearing the exact same thing. I'm not having any problems tho just a rattling sound from the front.

boiler123 · 05-25-2010, 06:13 PM

Any update on this? I'm experiencing the same issue

shuarma · 05-25-2010, 06:16 PM

does it sound like its coming from under the car? if so i have the same problem...the cats are lose. it usually happens to me when accelerating in low RPM's. hit up BMW if you're still under warranty i'm sure they'd be happy to help.

Haven't taken it in yet but that's exactly what it sounds like. And at low RPMs.
Gonna take it in soon. I'll post the result.

The rattling sound accoring to BMW dealer at Bayside Queens NY " is a natural sound coming from the wagesgate around 20 to 30 mph and should be left alone" With that said im staring to hate BMW dealerssssss

fdriller9 · 05-25-2010, 07:58 PM

I have a rattle as well but I have a NA N52. I think it's my water pump.

My ride is @ the dealer for this issue and my problem is exactly the same as the one you have described-rattling noise coming from under the car at low speeds. For me, the rattling occurs @ 30-40mph, in 2nd or 3rd gear.

HawgToth330 · 09-08-2010, 11:33 AM

I too am having a rattle sound..

Happens when accelerating.. Can only hear it inside the cabin.. Sound resembles a loose, plastic fan flopping around.

jayy178 · 09-08-2010, 11:41 AM

my dealer said same thing: a natural sound and is under normal operating procedure.

Potty_Pants · 09-08-2010, 11:57 AM

same noise... same response.

dealer years ago was able to duplicate it on another manual car...

is any of the above posters driving an automatic ?

ppp

Three_thirty_I · 04-15-2012, 11:28 AM

Sorry to dig up an older thread, but my '05 E90 330i manual has been making this rattling sound pretty much since I got the car, but it seems as if it is more noticeable these days. It does it at lower revs and under normal or heavier acceleration. My first thought in the beginning was that it might be the exhaust flap actuator when it opens, but then the frequency and time that I hear this rattle does not make sense, so must be something else.

Also, since I bought the car it has always suffered from the brief throttle hesitation when planting your foot, especially at slightly lower revs when wanting to quickly accelerate past a slower moving car.

Could this be both related and an issue with one or more of the coil packs? Vanos seals?

The car is still under motorplan (few months left), and I did mention the hesitation at the last service, but no change.

So basically I want to know what to tell them to check so that they can't play stupid and not find the problem which will then escalate later on and become mine!

So any suggestions or ideas would be much appreciated! Oh, it's the N52B30 engine that I have, so the earlier Valvetronic engine...
