Thank you for confirming that the UK offerings are the same as those on the continent.
One thing I haven't decided upon is how to handle engine specs, since much of the rest of the world uses kw and nM. I've been converting these to HP and lbs-ft, and could have the program convert them back for members outside the U.S. This will probably lead to some minor discrepancies, though. |

I entered all of the powertrains for the 3 earlier, and when I converted them to HP many that should be the same didn't quite match any available in the U.S. This might be because the calibration differs a bit, but I also think that BMW likes to round the numbers down in the U.S.

And, were you using SAE or DIN horsepower numbers? Those two differ in terms of calculation method.

well...
the 123d is 204hp which is 150kw and 295lb/ft of torque which is 400Nm the 120d is 177hp which is 130kw and 258lb/ft of torque which is 350Nm can you just input them manually?

SAE. But if you look at BMW's U.S. HP numbers, they almost always end in a 0 or a 5. So they've been rounded in many cases. Convert the U.S. numbers to kw, and they'll not match the European specs as a result. They'll only be off by 2 or 3, but this still might confuse people or make them think the site is full of errors.

Inputing the engines is easy. Coordinating the codes across model years is the tedious bit. I need a better way to manage the database. And also a better database structure. Problem is that there's always something else that needs doing more...

Updated results were posted today. I've been expecting the reported repair rate to improve for the 1, since last time it was well above that for the 3, and I see no reason for this since the two models are closely related.
Well, the new result of 89 repair trips per 100 cars per year isn't much lower, and remains nearly twice that for the 3. One of the reasons: a few reports of cracked and/or dislodged 3rd brake light lenses. This is a part unique to the 1. A big thanks to everyone who has been helping. We'll have further updates in May, August, and November, so additional participants would certainly be helpful. We now have a separate results page for each model.

Thanks for the info. If you could dig up an explanation for this, I'd love to know it. Are the engines actually much different, or just the ratings systems / policies?

The biggest thing I noticed though was that Canadian vehicles seem to be rated for a much, much lower max. gross load.. on the order of 70 or so kilos for some vehicles... and seem to have (on average) higher curb weights. That said QA is not a high priority for these numbers and I would not be surprised if you find a statistic or twelve that is completely out of whack on bmw.ca... But if you do, let me know and I can fix it. |

Higher curb weights could follow from higher levels of standard equipment. I'm sure some people here know a lot more than I do here, but can't you order a BMW in Europe with a lot less stuff on it?
As far as I can tell, many curb weights from many manufacturers are BS. Sometimes a car gets a new engine, yet the curb weight stays the same. Does the new engine weight exactly the same amount the old one did? Not likely. The max load--could be a matter of regulations, and how much of a buffer is expected. Or maybe we get different brakes, cooling systems, and/or tires? On QA: I regularly check many different auto sites. They ALL have plenty of errors. |

I apologize that I still haven't found the time to input the European powertrains. They're coming, just extremely busy, and not enough hours in the day.
The May results are fast approaching. We especially need more 2009s, to see how their repair rate compares to the 2008s. Many 2009s here? Car reliability research |

Request to an admin/mod:
I just noticed that this thread has been moved from the general discussion to maintenance. Can it be moved back? I'm trying to provide the best possible information to the community. Placing this thread in the servicing forum could lead to distorted results, based on who is most likely to visit the servicing forum. |

Anyway, in a few weeks we'll start previewing the next set of results to participants. More always helpful. Especially need 2009s. Details: Car reliability research |

We've updated the results for the 1-Series to include owner experiences through the end of March. A big thank you to everyone who helped make this result possible.
With a repair frequency of 79 repairs per 100 cars per year, the 2008 has improved to about average, but still close to "worse than average." A common problem: the third brake light seems to have a tendency to detach from the trunk lid. These cars are of course young, and it remains to be seen how they'll fare as they age. With prompt quarterly updates, we'll track them closely. The more participants we have, the better the information we can provide. Especially need more 2009s. BMW 1-Series reliability comparisons |

103 1-Series owners now signed up. A good start, but more are needed to provide precise results for all model years. Especially need more 2009s.

As to your comparison to the 3-series above, are you comparing all 1s to all 3s? I think you would see a significant statistical difference if you compared just the 135 to the 335, or 128 to 328. My impression is that a high percentage of 1s are "35" spec with the N54 engine, but a much lower percentage of 3s have the N54 engine.
Seeing as how the N54 is inherently going to require more servicing, you might want to compare the two cars based on engine type. |
