Hi,
I have a BMW Série 3 E91 318i (2012, 115k km, BMW N43).
I get a noise only when cold, between 1500–3000 rpm.
It sounds more like an air/vacuum noise (whooshing) than a metallic knock.
No warning lights, car runs fine, and the noise mostly disappears when warm.
Could this be a vacuum leak / intake issue / PCV?
Video attached.
Any ideas?
Thanks!

Mechanic said the engine burns oil and i had the EGR blocked off in the recent service and was thinking to get the DPF removed as well. It drives well and no alarms other than the DPF filling up quickly. what are my options here?
I CAN’T GET IT OFF!!!
Me and TWO of my mechanic friends have been trying for 2 days to get this stupid butt ugly wheel off and I feel defeated (and highly ragebaited).
We’ve removed most of the foam around the wheel (I can still tell where the original entry point dimples are), yet we can’t find any spring to push. We can easily see this spring on my new wheel which is waiting to go on.
Are there any last resort options?
Researched online and found out you can find the trans health via Bimmerlink which i bought. As below, all clutch values are relatively healthy except Clutch A. ZF has updated their fill pressure range to be +-300 now. With this being said, the trans is somewhat compensating (likely through friction in the fluid) to maintain pressure in clutch A).
By changing the fluid, i risk exposing this worn out clutch, but this will likely last another 150,000km+ with no issues. as -326mbar is minor wear (typical for high km).
Best case scenario with REAL data from my car - to NOT touch and NOT perform a transmission service. This app Bimmerlink only cost $50 and to be honest it is CRITICAL to figre out if you are required to do a trans. If everything is healthy, do the flush, if anything is borderline high range, better to not touch.
Been doing this on cold start, doesn’t throw any codes or anything. I wonder if this is the Turbo oil feed pipe giving too much and it’s coming out, or if that means i gotta get to the turbo myself. If anyone else has had this same N26 issue that would be amazing if you had a solution. 2016 BMW 428i Rwd
So for context I own a bmw 320i f31. About a month ago I started getting this rubbing noise that sounds like its under the driver's seat mat or just in front. It makes this noise when the car starts up especially on cold start then dies down a little. Also happens when I get on the gas a bit and when turning corners semi sharply. It sounds like a rubbing/knocking noise. I can think of a few things that it could be, but im just looking for some input or insight if anyone has experience or anything they can add. Ill make a list below of what I think it could be.
1: Control arm bushings
2: Ball joints
3: Strut top mount/strut bearing
4: Sway bar links
5: Exhaust rattle/Vibration.
I recently got a varex valved muffler installed about a month ago and thats when it started to get louder and the vibrations felt more violent i guess or more noticeable.
Hello bmw techs, I got a check engine and while driving recieved the drivetrain malfunction error followed by limp mode. the dealership identifed an issue with the 2nd bank intake solenoid. recommended replacing vanos actuator. how logical is this and also what am I looking at in terms of labour and parts? thank you.
Took it to a mechanic today who has changed the engine cover grommets thinking that was the issue however it is still rumbling at low revs. Any ideas what this could be?
I was doing a U-turn and misjudged the amount of space, so I went over a curb and it grazed the control arm on my RHD BMW M4 G82. How bad does it look? Should I be concerned?
I’ve been using INPA 5.00 to read values and codes and I’ve started the initialisation process for my sunroof, though this one ended properly it did give me a error in INPA and I had to close it.
Now my car won’t start again lmao, it’s the EWS because of manipulation. Now I’d like to reset it, but I can’t find the right option to do so.
Is there anyone that can help?
Thanks!
so i decided to tune my little project car (b48), wondering what spark plugs work well with a stage 2 tune (BM3). it seems that you need colder plugs to prevent misfires etc. been looking around, even asking chatgpt for some recommendations but haven’t got the clarity i’ve been looking for.
Just got a bmw 535xi and using the bluetooth default is dog water and was hoping anyone could help with some decent advice with like suggesting a plug and play module or something idk how this works thanks! Also i believe its idrive 4
My battery was good but when i checked the negative terminal it has corrosion. Do i need to replace this?
It’s comes on sometime and when I turn the car off and back on it goes away bmw x32011
I googled and it said it may have something to do with another ground issue or my carbon filter near my back left wheel.
So i have a e71 xdrive35i 2009, and iv been very confused with it since it looks very similar to both engines and i just wanted to know which one it would be. Also im not sure if this confirms it but i see 2 donwpipes, which i think its a n54 but also the intake system looks exactly like a n55. (im a noobie at this so dont judge)
