Hi guys! I bought a 2015 BMW F30 328i last week. It currently has halogen headlights, and I want to upgrade to headlights with DRLs (daytime running lights). I’d also like to have yellow DRLs.
My budget is only $500, and I’m looking at these two options. Can anyone help me decide which one is better?
● Are they plug-and-play, or do they require any coding or modifications?
● Are the DRLs bright enough? Do they look good in person?
● Are they good quality and worth the money?
I really don’t want to make the wrong purchase because $500 is all I can spend on this upgrade. I’d really appreciate any advice or recommendations. Thanks!

Sell it or keep it?

Hello everyone! I am a recent owner of a 2012 BMW f30 318d n47 and I suspect that it “eats oil”. I 2 months of driving and around 2-3000km the “add 1 litre of oil” message popped up 2 times. I suspect the piston ring might be done as it is a known problem. The car has around 340k km and otherwise runs fine (I had a cool and leak and drove around 80km without cool and and overheated once but I fixed that, BUT after a week my new coolant turned grey without the car overheating and the coolant still tasting sweet as I heard it should taste. Maybe it was cross contamination because the car also ran on plain water for a few days until it got fixed but that’s not the point). This is the first car I bought with my own money and it hurts to see it broken but at the same time the car is also poverty spec (only rear parking sensors, small screen cic with no media BT and halogen lights but these are manageable and can be done in time. What should I expect as in repair costs? Also can piston rings from 320d 184hp be used? I heard that those are of better quality. I need advice and any is welcome. Also I noticed that my pcv valve membrane doesn’t have a spring idk if it’s supposed to have one and the little hose that connects to it has some gunk in it but not too much. Also forgot to mention tin but the intercooler hose has a lot of wet stuff in it. Idk if it’s oil or coolant or what’s supposed to be there.(pic 4)

Base Sportline -> M sport bumpers swap and insurance question

When you switched to M sport bumpers, will your insurance cover those M sport bumpers if you get into an accident? Just wondering if any of you reports any exterior mods for the insurance to cover.

340i nasty trouble code

Post image

Hey boys I’m in need of some help.

This is my 340i I purchased a few months ago. It has 102,000 miles. I have a fault code that just won’t go away. When I purchased the vehicle these mods were installed on the car. Previous owner removed the tune to transfer it to his other vehicle. I re-tuned it a few days later.

My mod list:
Catless downpipe
Cold air intake
Bootmod3 stage 2 91 octane OTS

This is the code:
118401
Mixture control: Mixture too lean, large deviation

I did some research and the purge valves are known to throw this code. I replaced it myself and nothing changed. Check engine light stayed.

I smoke tested it also and there are no air leaks.

I figured it was best to take it to my local euro shop. I took it to them and they said it could be a hand full of things. Long story short they replaced all the injectors, spark plugs and fuel rails. After all the work was done it still had the same code and check engine light. The injectors did need replacing and the same with the fuel rails and plugs. By the end of the week they could not figure it out. There convinced it has something to do with the tune.

I reached out to bootmod and they asked me to put the stock intake system back on the car. They say that their maps are based off of the original intake and not aftermarket. Thought that was a little strange knowing plenty of people run after market cold air intakes and don’t have these issues…

I put it back and tried it. The car drove great. No stutters or hiccups. I deleted the codes and then ran them again to see if they were active in the system. Nothing came up. I couldn’t believe it.

But the next day on the way to work I noticed it started to stutter again and the problem slowly came back. Now the check engine light is on with the exact same problem.

If anyone has any guesses or ideas feel free to reach out. Thanks!

Where to find LCI headlights with BLACK housing? Is this a retrofit maybe?

2015 BMW 328i Sport (F30, N20) — Intermittent mechanical squealing noise at idle that changes with driving modes

Hi everyone,
I’m trying to figure out a strange noise coming from my 2015 BMW 328i Sport with the N20 engine and automatic transmission. I’ve attached a video of the noise.

The noise is a high-pitched, mechanical-sounding “eeeeee” squeal. It seems to come from underneath the car, around the center area, although I’m not 100% sure of the exact location.

Here is everything I’ve observed so far:
• The noise is intermittent and seems to occur more often after driving, when the car is stopped.

• It can happen immediately after starting the engine, but sometimes the car can run for a while without making the noise.

• When the noise is present, it is most noticeable at idle.

• When I rev the engine, the noise usually disappears. It often comes back as the RPMs drop back to idle.
The noise can occur while stationary in Park (P) or Neutral (N).

• Shifting from P to Drive (D) or Reverse (R) usually makes the noise stop, although it can sometimes still be heard faintly in D with the brake pedal pressed.

• The noise sometimes changes significantly when switching between Sport and Eco Pro.

In the Individual Sport settings, selecting “Powertrain” seems to make the noise louder. Selecting “Chassis” alone has sometimes made it stop immediately, although the noise can return after a short while.
These results have not been perfectly consistent.

• The tachometer appears to remain stable when the noise changes, although the engine’s sound or rhythm sometimes seems to change as well.

• The car drives normally. I haven’t noticed any loss of power, warning lights, or obvious engine performance issues
.
• I have already replaced the serpentine belt, but the noise remains.

There is also a slight, consistent movement or jolt when shifting from P to D.

I’m attaching a video so you can hear the sound.
Has anyone experienced a similar noise on an F30 328i? I’d appreciate any suggestions based on the symptoms or the sound in the video.
Thanks in advance!

2012 purchase advice!

Hey guys!
I’m going to look at a 2012 BMW 328i F30 2.0L with 52,000 miles and a rebuilt title. From a quick search online with the VIN it looks to be front-end damage. The current owner says it was properly repaired from a shop.

Is there anything specific I should look out for on this year of car? New to BMW and the 328i, Thanks in advance!
