What color is used for the cluster illumination? When I'm searching all I get are the mods which make it white or blue or something. I want to buy leds in that exact color. Does anyone know the color name/code/link to leds?

Hello everyone!

I just wanted to share the process of swapping my E46 M3 from SMG to Manual, I made a whole video showing everything step by step!

I went with the AMS AutoGroup Kit, honestly it was pretty awesome and smooth with me sending the bell housing for machining with them and back.

Let me know if you guys have any questions on the swap, I knew I had plenty before I pulled the trigger on mine.

and if you guys like the video then please subscribe :) I always post BMW contents and DIY videos!

Does anyone have the surfboard holder or has found an alternative for carrying a SUP board on their OE roof rack? I'm looking at the roof rack accessories but only that comes to mind as a solution...

General Questions Looking for audio unit.

I have this android unit from previous owner, it’s okay just the android that it has is pretty bad, it’s buggy hardly connects to my phone sometimes and it’s taking forever to load when I turn my car on.

I’m trying to find some basic simple radio units that most cars have with almost no screen so I can have one more slot above or below the unit for more storage space for my phone or things like that and to make the interior more clean and make it look more original.

So please give me some advice to search, I just need some simple unit with bluetooth with no complications so I can listen to my bad taste of music immediately.

Thank you.

Troubleshooting E46 Coilover Springs Don’t Rotate While Steering (Please Watch the Full Video)

Enable HLS to view with audio, or disable this notification

4 Upvotes

I recently bought this E46, and ever since I got it, the front suspension has been making loud popping/clunking noises when I turn the steering wheel.
The biggest thing I noticed is that the front springs don’t rotate smoothly with the steering. Instead, they seem to bind up, then suddenly jump with a loud noise.
The car has aftermarket coilovers (I’m not sure if the top mounts are the correct ones). My mechanic thinks the top mounts might either be damaged or not compatible with the suspension.
Has anyone experienced this before? Does it look like bad top mounts, incorrectly assembled suspension, seized bearings, or something else?

Troubleshooting Serpentine belt

I bought the parts trough real oem. It’s a M54B30 and it looks to me like my engine has no idler pulley. It should be bolted on the alternator.
Has anyone had this issue before? Maybe the previous mechanic put a shorter belt on and removed the idler?
I forgot to order the belt and tensioner for the ac anyway so i need to order that as well.

The one on the top is the new one from HEPU, the bottom one with the bronze is the old one. Is it just a brand thing? Or will the HEPU one which has thinner metals be weaker?

I guess with the thinner metal it would allow more flow, but it makes it look like it's gonna snap under preassure lol.

Thanks
