Which engine should I buy? 428 vs 430

zax · 12-04-2018, 12:05 PM

Hello everyone,

I was a happy BMW owner for about 1 month. It's 2013 year and I bought it with 78,000 miles. Now, the engine is damaged caused by the broken oil pump. The crankshaft is broken and I'm waiting for the repair estimation from my friend who is a BMW expert.

Anyway, I heard about the issue with the oil pump (and basically about the defectiveness of this engine). To my surprise, people are saying that 330i and 430i (counterparts for 328i and 428i) are pretty good engines with no issues with oil pump and things like that.

So I'd like to know if what they're saying is correct. Let's be honest, they could just hear that somewhere and it has nothing to do with the truth. I believe a Bimmerpost is a place where I can find the answer.

I'm basically wondering about BMW 328, 330, 428 and 430. Which one of them is the best when it comes to the engine failure?

(Also, I didn't know where to ask this question and I'm surprised there is no thread like that on Bimmerpost. I'm not sure if I used the search wrongly but if there is already a thread with that issue then I'd be grateful to link it here)

Thank you,
Mateusz

The B46/B46 that you're referring to (330i and 430i) has proven to be very reliable thus far, however it's so new that there isn't enough data out there to generalize whether or not it's more or less reliable than the N20 (358i and 428i). The only trending issue so far is undiagnosed coolant loss, however it hasn't become a major issue.

Is your shop giving you the option to install a different engine than what your car came with?

sspade · 12-04-2018, 12:19 PM

I dont think you would go wrong either way. Shoot for a 2015 or newer and you'll be fine.

zax · 12-04-2018, 12:20 PM

Sweeney921 Oh no, I'm about to repair that F30 328i and sell it as soon as possible. I'm not going to repair that car in an authorized dealer as my guarantee already expired. I think I'll repair it on my own with that BMW-expert friend.

Right after that, I'm planning to buy another one with B46 engine (still wondering if 3-Series or 4-Series). I'm just worrying that the same issues will come in and I'll lose a lot of money again. I can't really understand the BMW's policy. As far as I know, they had issues with oil pump in every 3-Series since E46...

sspade , are you sure about that 2015 or newer? I mean, there are no more issues with oil pump? What came to my mind right now is repairing my current BMW (328i 2013) with the proper oil pump (if there is one). However, I'm still really worried about it.

alohasurftoad · 12-04-2018, 12:42 PM

although the n20/26 is supposedly a bit more peppy than the nicer sounding b46/48, i'd get the b46/48 due to being a closed deck (sturdier) design and an air/water intercooler.

in late 2014/early 2015 is when the timing chain and valve guide issues were redesigned for the n20/26, thus the recommendations of 2015 or later if going with this choice.

MY2015+ vehicles powered by N20/N26 have updated part numbers for timing chain and components... of which, Im pretty sure the oil pump you are speaking of is included.

I have a 14 but if I were to buy a new one today I would get a 15 or better for ease of mind.

Not yet. The timing/oil chain issue with the N20/26 didn't start showing up until there were a lot of engines with at least 50k miles on them. That point came about three years ago. There was a redesign with engines built after Jan 1, 2015. A year ago BMW extended the warranty to 7 years/70,000 miles. It's all been well publicized here. Your dealer certainly should have been aware of it.
So far so good on the B46/B48, but what the future holds no one can say.

I agree with Bill....it is too early to determine the reliability of B46/48/58 engines. In theory, they are supposed to be more reliable and stronger, but without more of these engines on the road racking up mileage, it's not a fair comparison with the N20/26/55 engines yet (IMO).

BMW NA (USA and Mexico) extended the timing chain warranty, but this does not apply outside of BMW NA (e.g. BMW CA does not have this warranty, at least none I could find), I am not quite sure how that affects the OP's region.

I think first, the 30i engine is a little too new to be able to gauge but the n20 has been, to date, one of the most reliable BMW engines ever, at least if you pay attention to the usual JD Power, True Delta, CR, etc.

Even though the numbers in the 30i are a tad more, the 28i, at least as tested in the 3 series (328 vs. the 330) is slightly faster but fuel econ is slightly better with the 30i but that also has something to do with transmission programming etc. in the 28 vs. 30 models. i have had extended seat time in the 28i n20 vs. the 30i' engines (3 and 4 series) and the 8ZF transmission and 28i combo is superior in my opinion.

Is the ZF 8HP still in the 330? Does it also offer Sport Automatic programming?

Yes, the 330i has the ZF 8HP50 transmission. It shifts like a sport auto, but I've never been able to get launch control to activate.

Silly question but was is sport from factory or did you do the coding for LC to be on, I had SAT but I had to code my LC on

Mine had SAT from the factory, but I didn't realize that LC is a separate coding variable. I'll probably try that out this weekend.

DarkStarBimmer · 12-07-2018, 09:14 AM

I didn't need to code in LC on my 330i, it was there from mile 0. It's pretty fun especially with the Xdrive.

bimmer456 · 12-07-2018, 01:38 PM

I never used LC I can launch it better without it. I believe you can set the rpm for it as the road surface affects what launch rpm to use. It also learns from each launch so subsequent launches should be faster.

brittany.saunders · 12-25-2018, 08:58 PM

I am on the hunt for some answers... I have a 2013 BMW 328i xdrive F30. My vacuum pump has recently started leaking oil which is causing a burning scent through my car's vents.

I have done some research and it appears that many BMW's get a recall for this issue but mine doesn't appear to have a recall. What should I do?

Billfitz · 12-25-2018, 09:12 PM

Get it fixed. Save your receipts, if it ever does become subject to an extended warranty you can get reimbursed.
