I saw quite a lot of m340i on sale on xhs, most of them are only used for like 1-2 years. I wonder if M340i has any unbearable known issues? any m340i owners here, can give any feedbacks on this. thanks in advance.

Mine Sep 2024, so far no issue. Typical issues like leak and all will come after 100,000km.

I think any conti also same, most after warranty period will start to leak either coolant or engine oil.
At least 340i is not hybrid, if not even more things to worry.

This is with B58 engine-it is a very reliable work-horse.

of course, BMW does come with its traits of issue.... just that local mechanics are pretty familiar with it- they can provide a solution quick ( might not be cheap compare to japanese car, but 50% of from BMW itself)

Even now- the hybrid system of mild hybrid or PHEV also they can "delete" off

Bmw m330i also many letgo after owner own for 2-3 years. Not sure, upgrade perhaps

Got few shop that able to convert from bmw hybrid to ice, but expect 5 figures price

yeah- perhaps after 2-3 years, they got enough of the thrill. and want to try something faster lighter......
how much can they let go - for a 2 years M340?




yes- for now 5 figures, perhaps still new and not many doing.
like iphone repair/change battery last time.

Expensive- but it is an option compare to the more expensive repair ba.

If im buyer, better buy ICE straight. Spend 5 figures cash for conversation, afraid system not matured yet, hence niggles issue along the run

sure- everyone has his view and preference

some like EV, some like ICE, some goes for hybrid. no one is right or wrong.

any regret owning it? i am considering this mode

if it is quite stable without any unsolvable issues. then i assume maybe the owners feel how heavy it is financially, then decided to let go after owning it for couple of years?

I owned a 2023 M340i for almost 2 years now and never once did it cross my mind to sell it.

I think most people purchase this car and let it go within 1–2 years because:
1) It’s not lightweight or ideal as a proper touge car.
2) Get bored after 1–2 years.
3) They bought it just to “try the B58 life” and move on.
4) Some just chasing that ownership high.. get in, mod a bit, and then flip it before depreciation kicks in.

For me, it’s still one of the best bang-for-buck performance sedans around.. Comfy enough for daily, yet still puts a smile when I floor it. Solid all-rounder.

Or could it be they jump to EV, cz i saw many G30 owners who letgo theirs 530i, said brought Tesla or other EV. Most said they started to bleed oil at year 6 onward, which is expected from Bmw or Conti, which need to spend some for seal changing, waterpump change to a better materials etc

Yes, my mechanic also told me better to just find 1 half-cut with the ICE engine system transplant and sell the hybirds components off even better.

how much price now after 2years?depreciate alot?

maybe it's demo cars

what about reliability?

1 or 2 years cars are most likely demo cars or used as courtesy cars but usually it is a good grab as the selling price already include all the depreciation and usually cheaper than the market value.

The B58 is one of the proven engines. So far, no issues for me. However, G20 will have the usual tie rod krok-krok issue. Which I think is a small problem, you can always send in SC for a warranty claim.

If you are looking for a 2nd hand unit, make sure to do PPI and ask SC to scan the ECU to see if it has been tuned before, because I would say most M340i will be tuned.

Own one 1 years plus, no issue.

demo, test drive unit, registered unit (loan/rental/subscription), accident/flood unit
Many possibility, if possible ask or check with JPJ/insurance agent got any past owner details to share, insurance claim history and most important get a professional mechanic to check the ride before getting it.

Chasing tesla easy job with this car

Ma pren actually sold for more than he bought, laughing to the bank

how? if this is the case, why that fellow dont go get a new one, or u mean he bought second hand, then sell to another buyer as third hand?

i am thinking to get maybe 330i m sport, cos i am not an aggressive driver, so the performance wise, i actually dont need that high (of cos i know sometimes u get the excitement when u wanna it.)but this one got harman kardon, what u guys think. i know paying so much more for the speaker does not make sense. hahaha

What is xhs ?

xiaohongshu.

If you were looking at 340 in the beginning, I'll assume you're looking for something more performance oriented? The 320 isn't bad, but if you one day butt itchy go try 340, you'll really wonder why you didn't go for 340 instead

May I suggest the g20 330i instead? Good enough power to be fun when you want to push it, and doesn't feel too heavy.

As for the harman kardon speakers... suggest you try it out first. If you care about the speakers, you might want to just go aftermarket speakers/amps anyway - the default offerings from BMW kinda meh unless you get 340, where you get the RAM high amplifier. 320 and 330 is RAM mid amplifier. Changing the speakers only makes a difference, but your money could be better spent elsewhere imo.

Personally drive a 330i pre-LCI, the default HiFi setup sucks. I spent money to upgrade OEM speakers + woofers (H/K), but that was a rookie mistake and I was too eager to commit when I first got the car. Changing the amp/dsp would've probably been better. But audio is a very personal journey, so I hope you find what works for you!

Yeh...the 330i would be a good balance for performance and Capex.

my first car MYVI, i sent it to the workshop to add tweeter, end up they use some thing with sharp end to open the case for the installation work, and i got some dented scratches on the plastic, now i really scare to let workshop out there to touch my car. I wonder if warranty will be affected after some parts are opened up for the installation work

yea , i mean going for 330i m sport, just found out i have typo there.

The 330i has gone through 2 updates this year. The early year ones is LCI2, while the mid year one has spec upgrade with 360 cam, powerboot, active cruise control and 19" wheels

The early year ones are on sale now. Which one did you get?

The B58 is one of the best inline engines ever made.

Kinda good price?
