Hello everyone, how are you?

First time posting here. Hope i do it within the rules.

Im having issues with my e46 330i , quick rewind some months ago i had multiple codes, including misfires, and banks too lean, so my mechanic we assumed it was the injection coils. For some reason ( i didnt notice at the time ) because the codes led to the top cylinders (4,5,6) he only changed those injection coils, and around a month later i pushed him into changing the first 3 coils too ( and all spark plugs)

We are now some months foward and my engine gave me another check light, indicating CYLINDER 5 misfire, and i personally changes only that coil, thinking maybe it was defective. And about 2000kms latee i got the same code for the same cilynder, so im guessing theres something else doing it.

What can i do now? The cylinder 5 code already came twice. I ordered all 6 coils that are arriving tomorrow cause i told myself maybe changing 3 at the time each time was just wrong and my mechanic did a shit job, so maybe the older ones wrecked the newer? Idk what else to do.

Should i maybe change all 6 coils and spark plugs all together ?

Or could it be something else?

Also while the engine light is on my car has intense rough idle ( no knocking sound)

Id appreciate your help, thanks for reading, and show me your e46's. Love me some nice builds.

Im 19 and i saved up some money to buy my first project car. I was thinking of two options either the e30 or e36. What are your thoughts? Which would be a more fun car to have. My goal is to restore it first. Then after a couple of years I’ll maybe turn it into a drift car in the future. Any advice helps.

This isn’t my first bmw nor will it be my daily.

I have a 2023 m340i for which warranty is about to expire in a few months.

When enquired about purchasing additional warranty for 3 more years and additional 35k miles, they quoted me 6800 pre tax. Is it worth buying that ?

Have had this since March this year I paid 1350 it's mot till nxt March 2027 I've only probably driven it 15times had oil pressure sensor replaced as engine management light was coming on after driving 13miles or so then took it to garage after my breakdown company told me it was oil pressure sensor cost me 300quid in garage then came out n the light was still on engine management one. Took it bk to garage n said its still on he said something about the solonoids Then had someone else look at spark plugs n 2nd one had oil in n 3rd then 4th had water so got head gasket done now it's gone into limp mode n over heating

I'm considering a 330e as a replacement for my cupra formentor hybrid. The cupra looks great but the noise of the wheels starts annoying me more and more (bad insulation).

I heard that the x- drive is very vulnerable when you don't change all tyres. Is it really a thing with the x-drive? I'd be looking for a car a couple of years old with max 60.000km, so no guarantee how it's been looked after. Better get the none x-drive?

I recently did a muffler and resonator delete but it will only pop and bang/burble on a cold start, it is only louder when driving and revving later on after a cold start. I want it to pop and bang/burble while driving and just in general revving after a cold start. Why does it do this? I thought maybe the deletes weren’t enough and I possibly have to get a down-pipe + tune. Is it just my car? 😅

Moin zusammen,
ich interessiere mich für einen BMW 428i (F-Baureihe) und bin dabei auf Korea X Import GmbH gestoßen, die den Import aus Korea anbieten.
Hat jemand von euch schon Erfahrungen mit denen gemacht oder vielleicht selbst einen BMW über die Firma aus Korea importiert?
Mich würden vor allem folgende Punkte interessieren:
Wie lief der gesamte Ablauf ab?
Wie lange hat es von Kauf bis Übergabe gedauert?
Wie war der Zustand des Fahrzeugs bei Ankunft?
Gab es Probleme oder unerwartete Kosten?
Wie lief die Kommunikation und Abwicklung?
Musste der komplette Kaufpreis vorher bezahlt werden?
Wie gut fühlt man sich als Käufer abgesichert?
Mir geht es ausdrücklich nicht darum, die Firma schlechtzureden – ich möchte einfach vor einem möglichen Kauf möglichst viele echte Erfahrungen hören.
Danke euch! 🙏

Hey all, I have a 2007 335i lowered on coils and I have a question about wheel sizes. I found a nice set on Facebook for a good price however they’re 255/55/18. I’m concerned by the 55 sidewall height and wanted to know if anyone has any experience running that or if you have any knowledge on whether they’d be too big. Thanks

Looking at getting either 2017 330 or 335d. Would like to know if they’re still worth it, as I get the feeling my lifestyle is sort of on the cusp of diesel/no diesel.

My work means I would be driving 330 miles round trip, at least twice a month to go home. As well as the occasional 400 mile round trip to see my parents (maybe 4-5x per year). That is approx 9k miles per year, without daily driving. No commute but would need the car for drives locally (very much rural, no city stuff). Only time I would ever regularly be in the urban would be those trips home, which would involve around 20-25 mins of London driving.

Does this seem appropriate for diesel and would I actually be saving money, given the better mpg but higher cost per litre? Considering things like 340i or 440i but I just want to be as economical as is reasonably possible on those longer drives, whilst having some good performance.

Hi everyone!

I'm looking to make my BMW F30 318i B38's single exit exhaust sound louder and better without making it obnoxious or with any drone. I have a few options like sport mufflers and res deletes, but I am wondering if anyone else has done it on their B38 318i and how it is sound wise and if any drone is there. A res delete would cost me $220 while a muffler delete would be $250. I'm also wondering if an exhaust tip would change anything sound wise or is just aesthetically pleasing. Where i live, we have some pretty strict laws with noise limits (Can't cross above 90). Let me know!

Yo guys, I got a question. I have a 2027 BMW M3 Dravit Grey. It’s coming together very nicely. Just got some front-mount intake bits. Now I was thinking about changing my headlights. Should I get yellow DRL or RGB? Let me know, and if you guys have a good website I could use to buy them off of, let me know.

Hey everyone,

I'm planning to retrofit paddle shifters onto my 2008 BMW E90 325i Automatic (pre-LCI).

My current factory setup is the basic steering wheel without any multifunction buttons (non-MFL). I am buying a used steering wheel that already comes with paddle shifters and MFL buttons, and I plan to bring it to an independent shop or BMW coder for the installation. (In Germany or Switzerland)

Since my car doesn't have the factory wiring for shifters:

1. Which retrofit harness is recommended for a 2008 pre-LCI model (e.g., BMS / Burger Motorsports)?
2. Do I need to buy any additional small parts, pins, or adapters, or does the harness cover everything needed to tap into the shifter box under the center console?
3. Is coding strictly required, or is it plug-and-play once the harness is connected?
4. Do you know any places in Germany or Switzerland that can do this for me?

Thanks in advance for your help!
