E92 330ci and 335i (Help)

Hi there all,

Please note before I start - do know that I am still very much in the research stage and still only know very little about both the cars in question.

The cars in question are:

Years 2008 and onwards -
1: BMW E92 330Ci M Sport Manual Coupe
2: BMW E92 335i M Sport Manual Coupe

After speaking to a few dealer mechanics most of them did mention that the 335i engines did have a recall due to their turbo and injector failures. They also mentioned that the 335i for longevity would be a higher risk factor due to the fact they have their turbo which will in turn cause problems later down the line. They were adamant that for power mid-range and top end speeds is far better with a joyful experience in comparison to the 330ci however owners would need deeper than normal pockets to keep it fit and healthy. The throaty sound of the exhausts on idle are sounds of pleasure for most. The future running costs will break the bank as things like turbos and boost pipes needing replaced and other associated parts.

With the 330ci they mentioned that it has the same engine as the 335i but without a turbo attached to put it simply. It’s far simpler drinks less fuel and overall is slighter under on power by 30-50bhp. Having a straight in line 6 naturally aspirated engine, owners have far less worries for things to go wrong. The general running costs are cheaper and with not much of a noticeable under powered difference it makes for a superb more affordable car of the same league.

After my few local conversations I find that they all concluded to the same conclusion which was:

335i – If you can afford it 100% buy it and be expecting large bills which will always hurt even the rich later down the line on repairs.

330ci – If you want to keep safe and still have a much respected engine with minimal problems down the line go ahead and buy one. It also allows for being tuneable. It’s a smoother running quitter engine which is far more responsive and has no lag whatsoever.

This has still really left me in a slight dilemma as I would like to now ask the individuals who actually own both cars their experiences and to see if it matches up with what little I have been told. So please do share with me your experiences with both cars..??

1: I would like to know the tanning potential with the 330ci, I mean how tuneable is this engine being it naturally aspirated?

2: Any common problems I should know about on both the 330ci and the 335i?

3: For both which engines do I stay away from (the ones which had a recall)?

4: The main core differences between both cars apart from one having a turbo and one being a straight 6?
I will be sure to test drive both cars and report back to you all with my results. In the meantime id like to thank you all in advanced for the help and advice.

Fire away guys…

Regards
Jazz

I only have one question. Are you buying warranty? If the answer is yes, get a 335.

If your at all interested in modding the 335 wins hands down. It may have a quoted 306 BHP stock but ALOT more potential, mine is running 380 because am a wimp and don't want to increase the boost too much or add meth buts lots of others(335s) on here are at 400bhp+ quite easily.

As for running costs I would 100% get a 335 with a warranty, even if for only just 1 year. When buying used you have no idea what the owner is not telling about the car and there is plenty that can go wrong with these. I waited for 1 year till the warranty of my car run out before modding it.

Actually servicing costs are surprisingly low, but you do need a 'war chest' for unexpected bills. The problem is the actual engine block is strong, hence you can tune it a lot, but all the bits that attach to the engine is very prone to just failing...This year so far I've put on a new autobox transmission gasket on the car because the old one was leaking, car in garage now waiting for a new water pump (BMW has apparently redesigned the thing a couple of times), and I've ordered a new High pressure fuel pump (again been revised a few times) to be fitted at the same time because I've had a couple of long cranks from cold so pretty sure the fuel pump will go at some point.

But despite the blip of needing all the bits done I still love my 335i. By far the best car I've owned, it's subtle enough that most people don't pay it any attention (unlike a M3) but every mechanic (and I've seen a few recently) I speak to love it...the usual comment been 'I bet that's fast' If your keeping the car stock a BMW warranty isn't a bad idea, but warranty and mods don't really work together.

There are lots of threads on the 335i. You will have more details if you tried a search, as there are some very good write ups and reviews by members who know their "stuff".

Look out for Dougboy, Idnan and e92fans' posts.

I just want to pick up on something you've said...about the 330i being "more responsive" and having no lag.

I've never driven a 330i so I don't know if it's more"responsive" than a 335i.

One thing I can tell you, the 335i is very responsive ( well pedal response in an auto, will never be able to match a manual, but that's another debate)....anyways, the torque kicks in at very low rpm and when i compare the power delivery to a TTS, the 335 doesn't feel "laggy" at all for a turbo engine.

BMW warranty is a must.
Modding is easy and some good parts out there! ( just a remap will give you an extra 70 horses).
People used to say, don't worry about it, just get the car and enjoy it. It's a forum and you will always hear people's problems on forums. Not all 335i will fail and we're just paranoid etc.
As long as you're aware of the "common" issues, you'll be fine. This forum and the n54tech have lots of guidance on how to deal with the n54 problems. I guess one of the advantage of having "common" problems is that people will find solutions to those.

I would be looking to get a warranty after I know a little more about these things. I take it a warranty is a safety net which in some cases can save your wallet full of cash.

Hi Guys,

Thank you all for your info so far. I am new to this forum and did give the search engine ago typing in variations of my search but did not seem to get the thread or information I was looking for. So please do bear with me.

I did however come across more information about the 335i than the 330ci. Today I visited a few dealers in and around the area. I had a thorough look through both the cars and did not really notice much difference between the two.

Both cars I looked at were motorsport packages and both of the same year 2009. Apart from the engine and the rear bumper/exhaust set up everything was the same. The interior, lights bonnet, bumper and electrical extras.

Am I right in thinking that there is little difference between both the cars cosmetically and the only real differences being is that a: the engine and b: the rear exhaust and bumper?

I loved both cars if I must admit. The main thing I did not do was test drive them, which was what I set out to do today however I have booked in for a test drive on both cars next week Saturday.

In the meantime is there any more information on the 330ci that I should know and or be aware off?

E92 330ci M Sport: Petrol Manual
1: Which engine code to stay away from?
2: Common problems?
3: How tuneable is the 330ci?
4: Stock BHP figure

E92 335i M Sport: Petrol Manual
1: Which engine code to stay away from?
2: Any other common problems?
3: Stock BHP figure

If there is any links to some threads you all think would help answer and reveal more information on both please do provide me with the links if you have them.

Kind regards
Jazz

Hmmm yeah, I don't think there are many 330i owners on here. Maybe try the US part of the forum.

Not sure about the"most desired" engine. But normally,
N54 for tunability.
N55 for reliability?

I have the n54 one.

can't remember on top of my head when did the n55 came out. It might have been at the same time as the facelift model.

What makes the N54 less reliable yet more tunable?

N55 for reliability - I presume subtle changes have been made to this engine , but id not imagine bmw making this engine restricted to further performance modifications - maybe im wrong..

Hello my e92 is an auto I did realise that your looking at a manual
I have been told the n53 330i is a "more reliable" version by my mate that works for bmw. Which is mine
I have heard about coil packs/high pressure fuel pumps problems but that is across 325 330i 335 also the electronic steering lock can play up
The 330 would b either 258bhp or 272 if you have the "power pack" from what my research found back when I was looking
All suspension and drive train is upgradable but for power a supercharger or turbo kit poss would req major upgrades to internal engine parts and then chassis etc
To be honest though a car can be great or a poor lemon just a matter of luck
Also I got my car hpi done at work as I work for ford and got my mate at bmw to check for recalls that have and haven't been done again mine was ok

Hope this helps good luck you can.always msg me if u want more

I own an e92 330i, all the e92 330i are 272ps and have xenons. Depending on the age you are looking at the 330 Can either have the n52 engine or the n53.

N52 is very reliable and simpler than an n53. However fuel economy is poor. Quiet and has a lovely engine sound (revs to 7000rpm).

N53 is not so reliable, more complex but has better fuel economy and lower tax band. Known to have noisy fuel injectors and cause largeish bills.

I have an n52b30 myself

With them being naturally aspirated they are not easily tunable, you would need deep pockets and still only get minimal gains.keep in mind they do 0-60 in about 6secs when driven properly... Is that not fast enough?

I'm not going to say the 335i is the most reliable car in the world, but the insured warranty scheme says something to me. In general, it seems that 335i owners are paying the lowest premium for an insured warranty.

Obviously as an insured warranty they are basing premiums based on claims.

I'm £41 per month with assist or £380 paid annually.

There is a significant performance difference even in standard spec. The 335i is 0-100mph in 12.4secs and the 330i is just over 15secs. That is a big margin.

If you go for a 335 all the E92s come with M Sport suspension and seats. The differences are just cosmetic things like the external styling, gear knob, steering wheel and handbrake. You can save a fortune if you opt for an SE.

The 335i may only be about 50bhp more powerful stock but it is the torque and the way it delivers the power that makes the difference. it will feel much quicker. Especially from low revs and at motorway speeds in 6th.

Hey no1_jazz how's it going man?

The guys make a very good point that if you have warranty and are Ok to put up with the hassle/time spent on getting issues fixed, the 335 is much better than the 330. Plus it'd almost be pointless to not at least remap the 335 to 350+ bhp. The 330 will be lucky to gain 5% extra power after spending £1k on mods.

Having said that, the 330 is FAR from slow IMO, especially on small UK roads. My 330d is 245bhp and I'm quite satisfied with it's speed even though I've come from a 300bhp petrol car that is 300kg lighter, so the 330i at 276bhp will be even better.

My recommendation would be to test drive both, and then see what you think, and if you're happy enough with the 330 then go for it as it will be cheaper to run and maintain. You won't know until you've tried them tbh.

I don't know.

A few years ago, Tony ( one of the tech mods on here) explained to me how the n54 engine works and why the issue with carbonisation etc, I didn't really get it!

When we say that the n54 is "more tunable", I think we're talking in terms of the availability of products on the market, most of them having been tested and tried by forum members. The number of maps available for the n54 to the selection of downpipes and intercoolers.

You need to test drive both cars.

N55 for reliability - I presume subtle changes have been made to this engine , but id not imagine bmw making this engine restricted to further performance modifications - maybe im wrong..
The n54 responds much better to simple bolt on mods and tuning and since it has been out longer and is more popular the engine has been pushed much further.

As far as reliability the main weakness of the n54 - the turbos has been sorted. Many n54's including those with recently replaced turbos seem to suffer from bad wastegate rattle. Whilst this can usually be masked by tuning, the problem ends up getting worse and eventually requires replacement. The twin-scroll turbo on the n55 is said to be more responsive as standard and probably the better option IMO if you can afford it.

Also, the injectors/HPFP which tend to fail are usually newer on the n55 cars and are later revisions. Coilpacks seem to be quite consumable on all petrol BMWs these days so there's no difference there. Whichever car you choose, a decent warranty will be a good idea.

You might have to wait a bit for a manual n55/54/330i as they seem very thin on the ground.

I have a 2010 330i Manual Touring.

As been said there are some reliability issues similar to that of the turbo cars so have continued with warranty.

Car is not slow but does need to be worked as there is no torque to rely on. Which is the fun bit. Easy speed can be threatening to the licence.

I think the later 330i had the larger 335 brakes from 2010 if I remember right.

But the rarity bit is the hard bit I think there were less than 10 facelift manual 330i tourings.

I too have the n53 and from what I can find out, it's seems the issues were at the start with injectors and coils. Mine seems solid. Driven around 9k miles in it since July and not missed a beat engine wise. There has been a drive line vibration which is being looked at later this week.

Mine is a 330i 2008 sport touring auto with paddles and has much bigger brakes than the 4 cylinders. Did they really change them in 2010?
