I agree this may be annoying but at the same time it shouldn't be a big deal. No need to do math in your head for that, just know you are always ~2 mph slower. FWIW, we all like German cars because of how well they are engineered so I would give BMW a benefit of a doubt for why they are doing this.

Absolutely, the GPS speed indication is going to have some lag to it, but that is easily accounted for with the help of the accelerometers to find times when the speed has stabilized enough to make a measurement. Every car I've purchased in the past 12 years has been within 1 mph of numerous local roadside radar speed indicators. Even my 13 year old entry level Toyota Corolla with its analog speedo is only off by a constant 2 mph no matter how fast or slow I'm going. |

I haven't looked at the tire specs, but I wonder if the outside diameter of tire on the 19" rim is smaller than the outside diameter of the 22" rim. Depending on profile of the tire, the outside diameters could be close, but I'm guessing the 19" rim is still smaller. So my theory is that BWM calibrated the speedometer based on the 22" rim size knowing it will be conservative for all available rims. I'm assuming the OPs rims are not 22" - if they are, throw my theory out the window.
Either way - I don't see why this is a big deal. It would bother me if it were the other way around. For me, I don't care if I'm going 75 or 79 ... speed is all relative to the vehicles around me. ** EDIT - Looks like the X7 only comes in 21" and 22" wheels - thought I was still on the X5 forum. My theory is out the window. |

Not really mad. Surprised and annoyed since I wasted my time taking my new car back to the shop and having them accept it (with same photos - so they knew exactly what was going on), coordinate a loaner, etc. for something that if I had been informed about there would have been consistent expectations.
Agree with Mark above that there is adequate technology to keep this precise, accurate and compliant regardless of vehicle factors or location. There is also no law or Federal legislation that mandates >5% off. BMWUSA's excuse didn't account for the extreme approach and wasn't consistent with the fact that as tires wear, your speedo will over-report your speed more. My theory is that they are taking a heavy hand to have consumers drive slower and have less/less costly accidents. Admirable but doubtful altruistic. It is more likely based upon helping achieve some statistic somewhere that BMWs are safer vehicles. |

What are people using to code this out?
I found this below on the MyCarly website but it appears to say that US models don't have an option: http://support.mycarly.com/knowledge...t-is-possible/ Speedometer: Correction’ speedometer • ‘corrected’ speed • true speed This coding does not work on US models. Per default the speed shown in the speedometer is ‘corrected’ by the car. This has the effect that the shown speed is a bit higher than the true speed of the car. (codable in KOMBI) |

Speaking for myself only I am pissed because a 110K German luxury car should at least be able to tell me how fast I’m going with a relatively high degree of accuracy. Someone else said it first and best, “Hey BMW, I am your customer not your child”
I’m also interested in getting my 2020 M50i coded to correct this asinine crap. By the way for those of you who tolerate this nonsense on the theory that it’s “safer” consider this. There already is a safety feature on the dash to warn of excessive speed- it’s the speed limit indicator which flashes when you go over the limit. That’s really all any reasonably attentive driver needs. However, since we now know the Car is constantly overstating our speed we now tend to ignore that built in warning. How does Teaching us to ignore this safety feature make us safer!? BMW if you are listening – get this fixed for chrissakes. If anyone can help me code this out, I will definitely make it worth your time and trouble. Kudos to Mark and X7-AR and MarkH62 for Keeping this thread alive. |

Yeah, this is pretty petty. Anyone who owns a BMW knows their speedometers are understated by 5 mph. I find that people who can afford a BMW can add 5 to a number pretty easily.
Oh, and smartphone apps aren’t very accurate either, that’s just about the last thing I’d be using as a benchmark. |

And I beg to differ about what "anyone who owns a BMW knows." How in the world would you know what I know?? Fact is, I didn't know and I suspect the great majority of first time buyers "don't know" until they make the same observations AFTER purchase. There's no value in posts which seek to judge how we should "feel" about the issue - that's a personal thing. This thread is about finding a fix not evaluating feelings. |

With technology so advanced 10% correction is unacceptable doesn't matter how safe BMW wants to play with rules.
Reminds me of my wife setting a small table clock 10 min ahead of actual time, that was to deceive herself waking up to the alarm in the morning. Point is, it never solved the purpose. This was before the first smartphone |

It's all about them. They are all that matters. They don't care how much traffic and road rage problems they create. The new fast/passing lane on I5 in Washington is the far right hand lane. Almost every day I am passing everyone in the far left hand lane while I drive in the far right hand lane because a bunch of "A" holes won't get out of the far left hand lane. About 6 months ago the Washington state patrol said they were going to start ticketing people camping in the left lane. It never happened. I deal with this every single day of the week! It's not just occasionally but constantly. The majority instead of the minority are driving in the left hand lane. Many of them are driving under the speed limit as well. Rant off. Sorry, didn't mean to hi jack the thread but you pushed my button! LOL... |

The other problem we have is the big Gravel trucks that don't cover their loads. I've lived in this state for 24 years and every single vehicle I've owned (over 6) has had at least one cracked windshield because of it. It's against the law to drive with an uncovered load. They don't enforce the law here. However, at the end of every month, you will see more state troopers parked with their radar guns out trying to get their quota of speeders. I wish I knew how get the state to start enforcing their own laws. Maybe I can try and get a class action law suit against the state for not enforcing the laws. |

When I had my E39 540i back in 1997, I realized BMW speedometer was over optimistic compared to its competitors. The E36 M3 I had at the time was a bit better, but still overstates the actual speed. I guess BMW hasn't changed all these years.
