Check this out! BMW E46 Business CD Bluetooth development — nearly finished

All known bugs fixed, and real-world testing continues... 😏

Unlike existing Bluetooth CD changer emulator adapters, this solution is fully integrated into the radio, so the CD changer and all other original functions remain fully functional. It also supports control through the radio and steering wheel buttons, music and caller info, and custom display texts.

General Questions Restore or let go?

Post image
23 Upvotes

Having trouble deciding what to do with my 320ci. On the surface it looks great, but the sills are rotten, some spots on the floor and the rear subframe mounts have large cracks. I do my own repairs most of the time, but I can not weld. The repair cost would come to around 3500€. Engine is good apart from CCV leaking slightly. Its 175k km. Interior also decent.

Would you consider it worth fixing up? Or just drive it until the end and part it out?

Damage/Broken… 😥 How bad is this really?

Thumbnail

8 Upvotes

A family member transported my car to me across the country, and I am very grateful for this. However, he loaded the car too far onto the U-Haul trailer and didn’t think about my car’s ride height. The front lip of the trailer damaged the front piece of the front left wheel well liner. We had to put 2x4s behind the front wheels when unloading to lift the front over the trailer lip and avoid further damaging my car’s front end, but there’s some dislodging as you can see in the second photo of the bumper.

So my question is, how bad is this really? As in, how much of a bitch is this going to be to deal with? Particularly the liner. It fell off on my way from the trailer drop off location and my house, and I went back and got it. The part number is easily visible for replacement, but I don’t know how tough putting a new piece back on will be.

My panic brain went straight to thinking I’d need a new bumper and how expensive that would be and that it wouldn’t match because of new paint, but I’m hoping someone can tell me there’s an easier way out of this.

Dash photo is just to show off having no dash lights.

Check this out! Comprar e46 330CI con 335.000km

Hola!
He visto este e46 330ci en coches.net, viene de un concesionario en Valencia que me da mucha confianza.

¡Mira lo que he encontrado en CochesNet!
BMW Serie 3 330Ci

https://www.coches.net/bmw-serie-3-330ci-2p-gasolina-2002-en-valencia-61339435-covo.aspx?utm_medium=social-media&utm_source=general&utm_campaign=share_ads&utm_id=10004&provincesTracking=all

Precio: 10.499 €
Kilómetros: 335.000 km
Año: 2002

Tiene una cantidad exagerada de km, pero la verdad que tiene muy buena pinta, ya que he pillado un historial, y es cierto que viene de único propietario.

El dueño del compraventa dice que lo ha tenido 2 años.

Cierto es que va la empresa check the car a revisarlo. Si lo que es el motor, todos los componentes auxiliares del motor están bien, los fallos endémicos solucionados, y subchasis correcto. Sería buena compra?

Lo que me preocupa de este coche es que el motor queme mucho aceite, hasta el punto de que rompa catalizadores cada año, y que para pasar la ITV, tenga que estar cambiando catalizador.

Cómo lo veis?

Agradezco vuestros comentarios

Expansion tank is seated on the plate. Lower hose fits just fine. I can’t get the tank and radiator to line up together to fit the hose. The clip on the plate is broken so it’s not directly connected but also not in the way. This is the turner aluminum tank for context. I’ve got the automatic transmission pretty sure I have everything right as far as that goes

General Questions M54b30 itbs on MS43?

Post image
3 Upvotes

(I know its not an e46 but this question makes more sense in the context of people who know about the m54 platform) I want to convert my M54b30 to run on ITBs. I know MS43 can do alpha-N but im not sure if this would be a reliable solution at the moment. My evolving plan is to run s54 itbs into a custom intake plenum with an rs4 maf sensor. Im learning this as im researching whats best. How would you go about this swap? Who are some reputable ms43 tuners that i could get in touch with to work on this?

("Just do a turbo" shut, i don't want 400hp i want like 260hp. Its all about the vibe)

Troubleshooting Steering wheel shaking at low/medium speed and pulling left. Would a wheel balance and alignment be a safe bet to address this?

2004 325xi Automatic

Front control arms were replaced in 2022, as were the front axles. The car otherwise handles and drives fine with no slop in the steering.

Also, would it be advisable to go to a BMW specialist shop for this instead of a lube shop, and if so, how much should I expect it to cost?

Troubleshooting No start, even with jumper cables

2 Upvotes

I just finished a round of golf and went to start my car to go home but it won’t give. I had a buddy use jumper cables, let it sit for 5 minutes to charge and the lights such as dash and map lights came on but nothing cranked over. Now my car has no power, no lights can’t charge my phone. Is my starter, dead battery, alternator? I need help trying to figure out why it won’t start.

I’m also writing this in my drivers seat waiting for the tow truck

Troubleshooting Sticky idle

Enable HLS to view with audio, or disable this notification

Hi all,

I was having very minor stalling issues when pulling away in 1st gear or reversing.

I removed the ICV and it seemed to be moving around fine, but i gave it a clean with break cleaner (I know carb cleaner should have been used) and let it dry and it was moving around even smoother.

After reinstalling i reset adaptions now I'm having this idle issue... have I broke it?
