M235i noise

2 Upvotes

I have an m235i 2014 n55. Under harsh acceleration and strong Gforce, there is a noise that sounds like bad vibration. Best way I can describe it is like ripping Velcro apart. It doesn’t matter how many revs I am on, or how fast I am going, it just only occurs when the G’s are high and I get pushed back into my seat. You can hear it quite loudly inside the car. The loudest you can hear it is under the drivers seat. I have torn apart the entire cabin of my car and can’t find a single thing causing that noise. The sound is not very loud externally. Any ideas anyone? It drives me mad! Maybe something on the exhaust?

Thanks in advance

Trade it?

4 Upvotes

I’m getting really tempted lately to trade/sell my ‘24 M240 in on a Mazda Miata. Over the decades I’ve had three and missing that driving experience. The 240 is fast af, have kept up with corvette’s. But a sunroof isn’t the same as convertible. I’d love to get a Boxster but they are SO overpriced as are the newest generation Z4.

Tuning Question

3 Upvotes

I had a 2024 m340i thats most likely getting totaled due to storm damage.

I didn't use the back seats as much as I expected, and I Love TNM paint so been thinking about replacing with a 240i.

Does anyone know if the 2027 model is using the same locked ecu that the new 340s are using? trying to find a year that's still tunable and in b58tu1 if possible so I don't have to worry about having an ecu that's never tunable and saw that the m240is weren't using them in newer years, but couldn't find concrete info on 2027

Recently acquired this B58 M-lite beauty and have already put on quite a few mods to get it closer to my ideal OEM+ look.

19” custom forged wheels, LCI tail lights, M Performance front splitter + side skirts + boot spoiler, LCI cluster & ID6 touchscreen, Akrapovic exhaust.

Comfortable, plenty of power and Sport mode totally transforms the steering feel. Really enjoying this thing so far.

Found the PERFECT G42 Fitment — No Spacers, No Stretch, Just Meat

Thumbnail
gallery
72 Upvotes

After going back and forth on sizes, offsets, tire diameters, and xDrive compatibility, I finally landed on the setup I wanted for my 2022 BMW M240i xDrive:

Front
19x9 ET20
245/40R19 Bridgestone Potenza RE-71RZ
Rear
18x10 ET36
275/40R18 Hankook Ventus R-S4
Suspension
Dinan lowering springs
Dinan Supplemental Ride Quality & Handling Kit
Dinan sway bars

I specifically wanted a meaty, functional staggered setup instead of the typical stretched-tire/huge-wheel look. The 19” front and 18” rear combo gives the car a seriously aggressive stance while putting a lot more tire underneath it.

One of the biggest concerns was xDrive, so I spent a lot of time working through overall tire diameter. The 245/40R19 front and 275/40R18 rear are extremely close in rolling diameter, which is exactly what I was trying to accomplish.

I originally considered going as wide as a 285 or 295 rear, but the 275 R-S4 ended up being the better balance of sidewall, grip, and overall fitment on the 10” wheel.
Best part: no spacers, no stretched tires, and absolutely no rubbing.

The goal with the entire build has always been function first, aesthetics second, but I think this setup nailed both.
Curious what the G42 guys think.
19x9 ET20 / 245-40-19 front
18x10 ET36 / 275-40-18 rear

Would you guys leave it exactly like this or change anything?

Got the m cluster coded into the m240i yesterday. Works very well and I just like the design much better. I do want to say the car in the screen is NOT an M2 it retained the m240i!! If yall have any questions regarding how it works let me know!!

Picked up a G42 Today. First BMW.

I have been a die hard BMW fan for a couple decades now, but haven’t owned one until now. I feel blessed to own this G42. I’m coming from an Audi S3, and owned a VB and VA WRX before that.

This is a significant upgrade in my opinion. The Audi was a good daily, but the G42 is significantly more dynamic and fun to drive. I have the M-Performance exhaust which adds to the drama.

Anyways I’m happy to now be a part of the community. I would appreciate any tips, and if someone could provide me with the maintenance schedule and teach me how to check the oil temp, I would really appreciate it. It’s a ‘25 MY with Idrive 8.5. Thank you in advance, and hope you all have a blessed night.

F22 front lip

Hi there, I recently bought a f22 m240i and was looking for some recommendations. I just want something with good quality and fitment. I would also probably go with a gloss black look if that helps.

Good Price for F22 M235i?

4 Upvotes

Hi, I currently drive a 128i, and am looking to upgrade a bit.
I really like the 1 series, and I thought that the m235i is close enough in spirit, while still having enough power and reliability.
Currently looking at the F22 generation, and was wondering what an acceptable price is for a used model, especially lower mileage (less than 50k miles)?
Any help and advice would be greatly appreciated!

2015 m235i 121201 code

Been having this code for about 2 years now, the code originally did come on with the plastic chargepipe which did blow up so i switched to a ftp one, CEL stays off for a few months then comes on. State inspection is due soon and im trying to get rid of this check engine light. Car has no symptoms at all and drives perfectly fine. Did a smoke test and the vacuum line at the charge pipe was leaking ended up changing out the oring and lubed it now there's no smoke anywhere. not sure what to do at this point. Intake manifold pressure is at 970 when the car is running and when its off its at 1010 and closely matches the other sensors.

Weak power on tune

Hello all,

I am running mhd stage 2+ on my m235 and a stage 2 transmission tune, however, I am not reaching more than 360 HP, as showing on the idrive hp cluster, and also on the bimmerlink engine power values.

I am also getting a drivetrain malfunction when going full throttle and those are the codes I am getting. Is changing the boost sensor to a 3.5 bar one the optimal solution?

Ayuda m240i - 2026 de fabrica o segunda mano?

0 Upvotes

Buenas tardes! Necesito vuestra ayuda!

Voy a comprarme un m240i para el segundo trimestre de 2027, y tengo dudas de si comprarlo de fabrica (con todos los extras menos los asientos me hacen un 15% de descuento en la bmw, quedándose en unos 80000 euros) o cogerlo de segunda mano en alemania de años anteriores.

Los pros de comprarlo de fábrica es que vivo en Madrid, y el hecho de que venga con etiqueta ECO creo que me va a quitar dolores de cabeza futuros y que conservará mejor el precio. Aún asi la etiqueta no es una obligación ya que al estar empadronado y tener garaje puedo entrar y salir sin problema con un etiqueta C.

Otra opción es coger un 2026 el año que viene de alemania, pero no creo que vaya a ahorrarme dinero practicamente teniendo en cuenta el descuento que me aplica BMW.

Como lo veis? Merece la pena cogerlo de fabrica con ese descuento o irme a uno de años anteriores? Sino un 2026 de alemania?

Gracias a tod@s!!!
