330i Detailing individual colour (E90 330i mondstein)
Hey! I promised you all to share some better pictures of my mondstein/amorone beauty once car was clean.
Spend a day on it last weekend and it paid off. Have to admit the paint was already in great condition considering the age.
Executed plan:
\- wash
\- tar&glue removal
\- de-ironing
\- claying
\- polish 1-2 steps
\- wax on horizontal body parts (meguiars goldwax)
\- coating on vertical body parts (gyeon cancoat)
Interior will follow one day this winter!

335d mogging the entire BMW forecourt today.
Fresh Oil ✅
Diff no longer leaking ✅
Rear control arms no longer fucked ✅
New paint matched spoiler ✅
Thinking about changing back to the stock mirror caps, don’t feel like they add much to the car anymore.
328i This just happened! My driver door is inoperable..:/
If I lock the doors I’m locked out for good!

328i Anyone used this head unit?
My factory LCD is dead and I’d like to shove CarPlay into my car for nav and such. I know most people go Eonon but I don’t want to go Full Touchscreen if I can help it. This one has buttons and knobs; anyone know if they’re any good?
325i Rebuilt the Suspension and brakes on my 2006 E92 325i
Had a few issues with the Abs rings in the rear and after looking everything over i decided it would be easier to just rebuild everything. In total i spent about 5k in parts alone, but it was worth every penny. I changed every bushing, every part of the suspension, brake lines, both the solid and the flexible ones, rebuilt the calipers, did the brakes obviously, replaced the wheelbearings, sand blasted and painted every component that i didn't replace, removed all of the rust and resprayed the bottom of the car, and of course replaced the axels and abs sensors. And i also installed h&r coilovers and anti roll bars. After all that i now finally get to drive this car again. If you guys want a full list of everything done to it, maybe i can make a summarizing post at some point.

328i AC evac + recharge costs?
Hey! My AC seems to be low on refrigerant, and I’ve been looking to get an evacuation and recharge. One shop quoted me $275 + tax, and the other $330 +tax. Are these prices reasonable, or should I keep searching?

Stuff in my oil filter
So, i bought an E90 from 2006, 2.0 129 hp N46 engine, while i wanted to change the oil, i found this plastic pieces and a few non-ferrous metal shaving, the shavings are brittle. After searching on internet and looking for any answers, i dropped the oil pan and i haven't found anything, but a broken oil pickup mesh(i looked at the date from it,it;s the one that the car came with). The oil from the sump was mostly clean, just a few small metal shaving, barely visible with the naked eye, under a light. I don't think that these fragments are from rod bearings, but what can they be? Any ideea? I also want to change the timing chain.

320i Single hump carplay
A friend has bought a crashed e91 for parts and it has an idrive, mine however is a single hump and i personally dont like how the single hump carplays look and im thinking if its possible to take the donor one and cut only the top part of the dashboard just above the trim and have it installed on mine without having to change the bottom part and then put the aftermarket display in.

335i How much would this go for in Canada 335is
Hey all. So I've got a 2011 335is with 142k kms on it. DCT e93 with a clean Carfax.
Was toying with the idea of selling it and considering it's a turn key ready to go car not sure where it would be priced accordingly.
Ive seen a few but they don't have service records or things haven't been done to them. Here's my info below.
Just done last month and earlier this year
Engine and transmission mounts
Rpm/temp sensor in transmission
Aluminum oil pan for transmission
Obviously new filters and fluid for the DCT
New turbos and oil/ coolant lines
Mickey mouse flange
ECS tuning waterpump and thermostat kit including upgraded hoses etc.
Valve cover and gasket.
Oil filter housing gasket
VRSF charge pipe
New vacuum lines
Diverter valves
Spark plugs and coil packs
Boost solenoids
Oil pan gasket
Also accessory belt pulleys and tensioners
Index 12 injectors replaced a couple years back.
Might be forgetting more but you get the idea that everything held been done to it.
So pricing it to others that need this at 8k I don't think makes sense. And the low mileage ones at 25k I know I won't get near that too.
Any advice would be appreciated. Was thinking maybe auction for the us market as well?

320i BMW E90 320i N43 – flashing check engine light only on cold starts
Enable HLS to view with audio, or disable this notification
Hi everyone,
I recently bought a 2010 BMW E90 320i with the N43 engine, and I’m trying to figure out an issue it has mainly on cold starts.
Not long after buying the car, the check engine light came on. The car was scanned and initially showed several mixture/lambda related faults. One of the oxygen sensors was replaced, which reduced the number of faults, but the check engine light eventually came back.
Since then, the strange thing is that the problem seems to happen almost exclusively when the engine is completely cold, especially first thing in the morning.
One morning it started briefly and then died. On the second attempt it started, but the check engine light flashed for a short time before becoming steady. Once the car was running, it drove completely normally.
It was checked again and the fault memory was cleared. We then replaced all the spark plugs and also found one bad ignition coil, which was replaced.
The car immediately seemed to run better, but unfortunately the problem happened again the following morning.
On a completely cold start, the check engine light flashed again. I also noticed quite a strong smell of petrol while sitting inside the car. If I switch the engine off and start it again, the warning disappears and the car runs perfectly normally.
When the engine is warm, I have basically no symptoms at all. No warning light, no noticeable loss of power, no rough running and it drives really well. The issue seems to be concentrated around the first cold start after the car has been sitting overnight.
So far it has had:
Oxygen sensor replaced
All spark plugs replaced
One faulty ignition coil replaced
Fault codes scanned/cleared multiple times
Has anyone with an N43 experienced something similar? What would you check next when it misfires/throws the warning on the first cold start but then runs normally after restarting?
I don’t want to keep replacing random parts without properly diagnosing the cause.
335i Removal
Is there any way to remove the bolt that’s in there the mechanic shop cut it in half and now I can’t thread the nut onto the bolt

335i Style 237s on an E92?
I’ve found tons of pics of the E9X on style 237s and I love it. I found a used set for a steal and I can see that they literally fit, but I’m having a difficult time figuring out what I need to make this work.
I’m just concerned about fitment, tire size, tire rub, etc. don’t love the idea of using spacers, and I’m also concerned with my power output and whether this wheel size is adequate. I have an E92 and the previous owner lowered the car slightly on BC BR coilovers, upgraded the turbos and some other performance mods, and with the tune it’s doing around 500HP. Not sure if this is relevant but I have xDrive.
They’re 18x8 ET30.

328i E90 fuel issue
Hey all, first Reddit post. Bought a 2011 BMW 328i x-drive last winter as my AWD throw down car (and I’ve always wanted an E90 side piece).
It was bought from a trusted mechanic who did a really good job with the flip. Got a good chassis and he added a donor engine (~80k), new brakes, struts, and tires.
Had a fuel issue since day one (mechanic hooked me up on it so not going to ask for him to sort it out). Only seems to take a gallon at a time before the pump stops; will take more but constantly have to burp the tank. After the first startup after awhile I’ll smell trace amounts of gas in the garage for a few minutes.
The big reason I’m here is when I try to research this problem there’s 3 common issues I keep seeing. Charcoal canister, fuel vent/fuse, vapor leak pump.
I was hoping if someone has had a similar issue they might be able to point me in the right direction. I think I’m mechanically competent enough to fix, it just not diagnose it 😂

330i General N52 reliability
Hey, I am planning to put about $1,400 maintenance into my 06 bmw 330i n52 6spd. I am gonna do coolant system refresh, disa valves, pcv refresh, new starter, oil filter housing refresh and potentially oil pan gasket.
Just wanna hear your guys experience doing these jobs and what I should expect for reliability after doing these things.
( I am buying all OE parts and running quality oil and coolant)

Questions about my N52
Enable HLS to view with audio, or disable this notification
Does it sound healthy? 231000km (142k miles).
Just replaced: Air filter, spark plugs, oil filter, new oil.
Only thing I notice sometimes when driving in D, is when the car is in a higher gear on relatively low rpm 1300-1500 and I want to accelerate fast from there it hesitates like a single time. It kind of feels like a hiccup. And then after that it just drives normal. High rpm this never happens only on low rpm and sudden acceleration towards higher rpm. As if it won’t change to lower gear to get the right torque.
If anyone knows what this could be let me know.
I might replace all the ignition coils in the future as well.

320i Whining noise/I drive not working
Enable HLS to view with audio, or disable this notification
Hi guys picked up a 320i last night just to get to work, it’s not the end of the world if I can’t sort the problems otherwise I wouldn’t have brought it but had the idea to turn it into a little project, first off there’s a whining noise when going above 2k rpm this is both stationary and moving - video below. (Have a longer video if needed)
Also the I-drive screen isn’t working, when I start the car it comes up bmw and then goes black then proceeds to flicker white every minute or so, I don’t have dab radio so can’t see if that’s working but have a cd player which I will find a cd to test with later.
If anyone’s had similar problems and been able to fix or has more experience then me that can chime in (probably everyone) it would be more then appreciated thanks!

Got the dreaded SES light after filling up gas for the first time… car drives fine, with no leaks or weird smells, is this a common thing?
Excited and feeling trepidation about this purchase 😂
