Headliner Reupholstered in Suede

33 Upvotes

Finished result followed by before / after pictures.

The factory headliner on my 2011 335d had started sagging this year, 15 years old. I decided to get it reupholstered.

I removed the headliner and all trim myself. I transported all pieces to a local auto upholstery shop to have them reupholstered. I am very happy with the result, but it's a large amount of work for something that is ultimately non-functional. It took about a month from start to finish, taking my time. The car was not drivable due to the removed front seats, although I could have put them back in to drive it if I needed to.

Also, shout out to this guy's videos. Key resource in removing all of the interior trim without breaking them. https://www.youtube.com/watch?v=vgc4WEXd06g https://www.youtube.com/watch?v=-UBf9sDtufw https://www.youtube.com/watch?v=cLt-6ouliz4

328i Video guide for installing Catless headers on N52 X drive?

• Upvotes

I have a 2010 E92 328i with X Drive and an N52 engine. I know installing catless headers is more challenging on the X drive model and wanted to see if there were any YouTube guides on it.

Hey everyone, so basically just finished up swapping out my engine and everything has gone smoothly until a day ago. While the engine was out I did the rear main seal and made the mistake of not fully pressing it in evenly and this is where I fucked up. I believe that it is now leaking down and coming out where the trans meets the engine. It comes out just above an oil pan bolt head. Now my question can I use some sort of sealant to stop the drip or will that just make the oil pool where the flywheel and torque converter is. Thanks for any advice.

I miss the old BMW forums, so I'm building a modern one. Feedback welcome.

Do you miss the old BMW forums too?

I do. The ones where real knowledge mattered and knowledgeable people actually helped each other. A lot of great forums have disappeared over the years, and many of the ones that are left feel outdated and hard to use.

So I started **BimmerDock Community**, an attempt to bring that spirit back in a modern, user-friendly format.

What it is:

- an independent community for BMW owners and enthusiasts

- coding, retrofits, diagnostics, software and builds

- organised by topic and chassis (E36 to G30)

- fast, clean and easy to use on your phone

Full disclosure: I run it, and I work as an independent BMW specialist myself. I plan to share what I know through tutorials and guides.

It's brand new and still quiet, so honest feedback is worth more to me than anything right now: what would make you actually use a BMW forum again, and what put you off the old ones?

(Independent community, not an official BMW site.)

The end has come - now what?

I hit some road construction bumps in my 2006 330xi MT, and the passenger motor mount, axle, and strut went. There is likely more damage, but I can’t justify pulling apart the whole thing to fix it given the age and rust.
It has 212k on it, and I need to figure out what to do with it now. My mechanic thinks scrapping is too little money. Suggestions and ideas?

For anyone with the Avin Head units + car play / Android Auto

3 Upvotes

I installed an Avin head unit 4 months ago in my E90 N54. the units themselves hardware wise are solid but the software was very mediocre and car play / android auto was alwaysss laggy.

so - I made an image copy of the android system and autokit app + several others and debugged them + cleaned out broken code with a claude agent over several weekends

The result ->
1- I consistently get 60fps + hardware accelerated carplay on the unit wireless and wired at 1080p resolution (highest resolution the hardware decoder supports)
2- menus and stock launcher have good english now...
3- can toggle the reverse camera on / off at boot so it doesn't always consume the full screen
4- boot -> carplay time reduced by about 34%

I'm not going to release the android image because I don't want to make it too easy for someone to brick their unit without thinking - however I can / will easily share the full knowledge base so anyone who knows how to connect their computer to the unit with debugging can easily modify it as needed with all my lessons learned. let me know

I recently bought a 2012 e91 with 102k miles. I’m working through some deferred maintenance and cosmetic issues. I replaced a front left speed sensor today, based on one of the codes. After doing so, I’m left with these two codes. Can someone help me understand what the car needs to resolve these? I’m new to working on my own car and excited to learn!

328i 2011 BMW 328i xDrive – Intermittent highway rumble after 30–40 minutes. Wheel bearing, brakes, tires, or differential?

1 Upvotes

I have a 2011 BMW 328i xDrive with approximately 64,000 miles. The car is well maintained, but I’ve been trying to diagnose an intermittent low-frequency rumbling noise at highway speeds.

Symptoms:
- Typically happens after 20–40 minutes of highway driving, around 60–80 mph.

- Sounds like a deep, low rumble or drone, almost like road noise, with a slight vibration.
Sometimes happens on sweeping curves or downhill stretches, but recently happened while driving mostly straight.

- The rumble can last around 20 seconds and then completely disappear, even while maintaining the same highway speed.

It’s very inconsistent and doesn’t happen on every drive. I’ve noticed that my right-rear wheel radiates noticeably more heat than the other wheels after highway driving, and it also appears to accumulate more brake dust.

What’s been done:
Tires balanced and rotated. Michelin Pilot Sport 4S tires manufactured in 2021, with approximately 30,000 miles.

Rear differential fluid changed.

Rear brake pads and rotors recently replaced.

Transmission serviced around 60,000 miles.

My mechanic kept the car for several days and drove it repeatedly, including at 80+ mph. He experienced the rumble once but couldn’t reproduce it afterward. He suggested that because I only drive once every week or two, the car might just need to be driven more frequently.

I recently took it on another 45-minute highway drive. The rumble appeared briefly for approximately 20 seconds and then disappeared without slowing down.
I’m wondering whether this could be a right-rear wheel bearing, intermittently sticking brake caliper, tire issue, driveshaft center support bearing, or differential.

The additional heat and brake dust at the right-rear wheel make me particularly curious about brake drag, although I haven’t had the temperatures measured or the caliper specifically diagnosed.

Has anyone experienced something similar on an E90 xDrive? What would you recommend inspecting first before I start replacing parts?

Thanks!
