335i Am I cooked?

Bought my 2011 335i N55 less than two months ago and I’m already four grand into maintenance and repairs. So far it’s had a valve cover leak, seized caliper, needed new plugs, coolant hoses, control arm bushings both rear wheel bearings and a new radiator.

I know there’s plenty more to come with the common failure items and at 120k I’m wondering if it’s even worth it to keep at this point. I’ve never had such a headache of a vehicle and this one has been single owner dealer maintained its entire life with 12,000 dollars of service receipts from its life.

Any advice? Yeah i know I’m preaching to the choir.

335i From beige interior to brown/black/individual colour.

Post image

Hello, I own an E90 with fully equipped beige sport seats. Seats are in good condition, but damn, I really dont like the beige interior. Problem, I can’t find a fully equipped E90 seat in different colours still being in good condition. As I live in Europe, I think about 3 options:

  1. Just put new leather on my old ones. It will cost a lot.
  2. Look for UK sport seats just in good condition and use their leather on my old ones.
  3. Find UK sport seats in perfect condition, fully equipped and change the modules for front seats.

What do you guys think? Which option would you choose?

just wanted to share some pics and appreciation for my ride after giving it some TLC. recently installed spacers and a black/chrome grill that I mix/matched from old sets. I tried the chrome frame with black slats and didnt like it on my car.

I've had the car since I picked it up in 2014 with 36k miles. it now has ~190k miles on the chassis and about 90k miles on the replacement motor installed a couple years ago. best car ive ever owned easily.

ignore the missing pedal covers as I was in the process of putting on some aluminum covers but havent gotten around to finishing itt. I think I have a few mods left (front lip and alcantara wireless charging insert - ordered, sideskirts, exhaust, anthracite/black headliner, replace lower bumper mesh, redo tints) and then I'll be done...maybe

328i 2009 E92 328 Oil Leak Advice - Am I Fucked?

So i've had this car for about 3 years now, oil change every 4k km (might be a little longer for this most recent upcoming change), and I happened to notice smoke coming out of my engine while stopping at a light. I thought it was something minor so I let it pass and now I noticed it happened again and it smelt like burnt oil. I will be booking an appointment to get this checked out but I was wondering if this is a big problem. Am I going to be fucked? Attached are some images below for where the leak is.

2012 BMW E92 328i N52 – Rough idle, smoke & hard shifts

• Upvotes

My E92 328i has a slightly rough idle, smoke on startup, and occasional hard shifts/kicks. Sometimes around 1,500–2,000 RPM, the car jolts like it’s slipping, but it drives smoothly on the highway. I replaced the MAF and the kicks seemed to improve slightly, but they’re still happening. Codes I’ve had: 2D06, 2A7A, 2D15, 2D27 and 2F08. The only codes I have now is 2E06, an the other codes sometimes come up as not present on my scanner, Could these symptoms all be related to an air-mass/MAF, or does it sound like a separate transmission problem? Has anyone experienced this on an N52? TIA 🙏

328i Weird noise on idle

I know about the lifter tick so I’m not worried about that but I feel like I hear something coming from where the timing chain is or like a pully. It only does this at idle, when I drive it goes away, anyone got any ideas?

328i Metallic Rattle/Ticking Under Car

Enable HLS to view with audio, or disable this notification

1 Upvotes

E92 2007 328xi with around 128k miles. Has a weird rattle under the car. The key thing is that I’ve only really heard this when the car is on ramps, i.e. at an incline I guess. I do not hear it day to day, but it’s worth noting that if I have the windows down while driving at a low speed next to a tall curb or wall, there is a similar metallic tapping sound heard (but only when pressing the gas pedal).

Overall I’m thinking this is either a loose heat shield somewhere, or a transmission low on fluid (GA6L45R). The rationale behind the transmission is that the pickup/filter is towards the front, so if the car is at an incline it could be struggling to suck in fluid?

Any ideas/thoughts?

335d Vacuum helps

1 Upvotes

Hello,

I’m having a vacuum issue on my 2009 BMW 335d, I previously noticed that the vacuum line running to my turbo waste gate actuator (on the front of the engine by the thermostat and water pump) was disconnected. It’s been like this as far as i know since i got the car 6 months ago.

I recently just replaced the line with a silicone hose (referenced this video https://youtu.be/ABK3uFIW-nA?is=JJdshcY18vxLfzQo) along with a couple others. I doubled checked everything and it all seems to be routed correctly.

Now, however, my car is giving me a “4530: 4530 boost pressure control, control deviation” code and throws it into limp mode almost right away. When I re-disconnect the turbo waste gate actuator line, the car runs “normal” like it did before with no codes or limp modes.

Any thoughts?

I also double checked all charge pipes and intake and everything seems to be attached correctly.

All help is greatly appreciated, thank you.

Changed the struts on my 08 328i finally, I used Monroe's oespectrum line for em cuz I couldn't afford direct OEM replacements and heard they were the next best to keep ride quality. I reused the old springs cuz they were still good tho

Anyone have similar experience with the stereo cutting out randomly?

2006 E90 330d

My stereo has been cutting out seemingly randomly for a few weeks and i'd really like to divvy it down before i have to rip the dash out or something STUPID lol. It cuts out as seen in the video regardless of how many things are on in the car, and i'm also sure it's not a battery issue or alternator issue as they have both been replaced within the last year.

I would like to assume it may just be that my stereo is dead after 20 years of service since it is just the stereo cutting out and no other electronics.

If anyone has had a similar thing happen and could share it'd be greatly appreciated 🙏

(Also have had stereo out and checked visible cables)

335i Funnier downbadge? 316i vs 316d

Thumbnail

35 Upvotes

I have a heavily modified pre-LCI E92 335i xDrive that I want to downbadge, I’m just having a hard time deciding between the 316i and 316d badge. Exterior is very understated, looks like regular traffic.

I know the 316i was cheaper, but performs better in a straight and around a track than the 316d.

The 316d was more fuel economic, got better mileage, and people would choose diesel models because it was cheaper than petrol, and it’s worse, performance wise, than the 316i. That said, it costed a couple thousand more up front, and the N47 diesel engine is notoriously unreliable and expensive to upkeep.

Long story short, what’s the funnier badge between the two? Which badge is more “I have the slowest BMW ever and also can’t afford a ‘real’ BMW”?

328i 2011 328i N52 — fluttering and rattling underneath after warming up

Enable HLS to view with audio, or disable this notification

2 Upvotes

My stock manual E90 recently started making a fluttering noise when revving or accelerating. It starts after about 5–7 minutes of driving, but sometimes goes away after idling for a few minutes.
It sounds like it’s coming from underneath the car, around the driver’s door. There’s also an occasional rattle when accelerating from a stop and a few quiet pops when letting off the gas.
The car still drives smoothly with no warning lights. Pressing the clutch at idle doesn’t change the noise. Has anyone experienced something similar?

Need help diagnosing the issue

Hey everyone! I own a 2008 E90 320D, the engine has ~100k kms on it, factory turbo but it has been tuned, not aggressively. After replacing my headlight bulbs I noticed that both charge pipes which are connected to the turbo and then to the radiator have been slowly slowly leaking oil. Now I can see that the connection is a bit loose and not all the way seated but this looks like far more oil than there should be.

Car doesn't smoke when driving or at idle, I haven't noticed any loss in power or any increase in oil usage.

What should my next steps be?

Oil leak?

Enable HLS to view with audio, or disable this notification

Hey guys I have a 2011 323i, bought the car about 4 months ago just got a vehicle inspection done.

Dealership said Oil pan is the only thing leaking at the moment. They did a vanos recall which I believe they took off the gaskets to perform the recall now I got the car like 6 days ago and put about 200km on the car.

Then this happened smoke is now coming from the left side of the engine which I believe is oil leaking onto the exhaust however the valve cover gasket was changed by the previous owner before I bought the car. Can this be because of the dealership and also is this from the valve cover gasket or what is this due of.
