1-series M Coupe, N54 engine and recent lawsuits

Hi. Long time lurker, first post here. I bought one of the first BMW 328 Ci's back in 1999. Owned it for 5 years before I totaled it in an accident. Have been suffering ever since, waiting for the right moment to jump back in. Was considering the BMW 335 IS, but have moved the 1-series M to the top of my wish list. However, given the challenges people are having with the N54 engine and the appearance that BMW may not have solved the problem yet, I'm curious, particularly now with the two lawsuits, if the 1-series M will still get the N54. If it does get it, does that imply that BMW has resolved the problem? What would people here like to see happen?

I'd be surprised the lawsuits changed the powertrain; that design decision had to be made long ago.

Really? Let me ask you this. Are you fine with BMW sticking that engine in the 1M? Doesn't it at least make you pause for a moment.....

Of course it does, but you don't buy BMW for reliability. We all thought the HPFP problem would be fixed with the N55 and it seems like it hasn't been. Some members over on the 3-forums have already had HPFP problems with them. They'll stumble upon a fix eventually.

Thanks for the info. Did not realize the issue was still occurring in the N55.

It appears, from what I have seen in a few threads on here, that the N55 and N54 utilize the same HPFP.

Additionally, the use of the N54 engine in the 1M supposedly had to do with more development time being logged by BMW, when compared to the N55--there just wasn't enough time with the 1er's life cycle to get a fully tested N55 into the 1M.

My personal problem with the choice of the N54 is that numerous media outlets have confirmed that the engine is that found in the Z435is, which seems a bit dodgy to me. ///M engines have always had some sort of special component to them...I realize that the 1M will get the suspension bits, wider tires, and other ///M goodies, but I am definitely disappointed that there isn't anything else unique or special about the engine that will be in the 1M...

When first reports of the 1M were surfacing, our BMW insider SCOTT26 had stated that the 1M would get a revamped version of the N55, which would later become the "basis" of the engine to house the F20 M3. Unfortunately, that didn't happen....

I don't think the problem is as widespread as it was in the N54 engine, but the N55 is still new, so we'll see I guess.

Yea, really. You don't think they're actually still trying to decide which engine to use, do you?

As for my engine wishes, I'd like a high revving n/a 6. But absent that, I'm fine with a N5x variant. I just wish it was a legit 7k rpm engine, and I'd like improved throttle response. My current N54 has been absolutely problem free. I suspect that either the hpfp issue is fixed or MANY 1M will have problem since it seems folks who beat/tune their N5x may have higher problem frequency.

No, I don't think they are still trying to decide. But now there are 2 lawsuits and rumor that a network will be doing a story on this, so that means an issue that has been under the covers will now be out there in full view. Questions will be asked. Likely, there will be negative publicity, particularly related to that engine. Certainly enough out there for BMW to review the situation.

You stated that you wonder whether the lawsuits would affect BMWs use of N54 in 1M. I said that I doubted it. You asked "Really?" I replied "yea, really", then I ask if YOU really believe that BMW is still deciding which engine to use. You reply NO! So we've gone full circle.

So lawsuits and stories. So what? Other than complaining about something that's not even affecting you since you don't own one, you've said nothing and just put out a strong troll vibe.

Wow, nice interaction dude. As an fyi, it does impact me. As I stated above, I will be buying a car. The 1M is at the top of the list. So, yes, what happens does interest me. Please try to remain civil. Thanks.

Many people are not happy with what they have had to go through to deal with this issue, so saying BMW will fix it doesn't mean all is good.

You clearly have a beef over it; if the prospect of it failing is critical, don't buy it. It's certainly far from proven to be resolved.

I understand. That is new info for me. Anyway, no need to draw this thread on any further if the issue exists in potential replacement engines. Hopefully, they'll have it under control by production as I really want the car.

Honestly I think that BMW has to have more motivation to fix the issue now. If they think that the general X35i crowd can be pissy, just wait until the M crowd starts having HPFP issues. Talk about making a big deal about the smallest things. This will set them off. I would venture that a lot of the people interested in buying a 1M have not even heard of the HPFP issue...but they soon will know a lot about it.

Not sure I agree. For all we know a new pump is coming out and may go on 1M first.

Still. It is OVERWHELMINGLY LIKELY that if you buy a BMW with hpfp, that you would NOT experience any problem.

I doubt anything will be different if this is going to be basically the z4is engine at 340 hp which has been apparently confirmed. This is an issue I would assume they are just going to hope prospective buyers aren't aware of or just don't care enough about because of the warranty.

I'm glad this thread hasn't been moved also like the one I made yesterday on the exact same topic. For a minute I was starting to worry the mods were protecting BMW.
