They don't publish that data but it is list as a camera update. At least according to my dealership.

There have been like 10 people in that thread posting, saying the exact same thing. That should be enough evidence. It's a drastic difference in suspension, transmission jerkiness. Before, lane keeping assist was completely useless. Especially compared to my accord and fords. Now it's actually useable. It also doesn't wander anywhere near as much as it did before, with or without lane keeping.

Also I could be wrong but I thought he was talking about wandering on the highway generally, not having to do with lane keep assist issues.

Oh my bad, sorry, I tried searching through the search bar for keywords "steering" and "wandering". Take it down a notch there cowboy. If you want to suggest I search for something I'd hope you'd at least come to the conclusion of it being related to what we are even talking about.

I didn't know you were referring to some random thread talking about how someone feels that everyone should get a software update because he feels like the suspension changed and the ACC changed and all these other things yet nobody can provide any actual concrete evidence of things that changed. That is why I was asking about information regarding where it specifically states that the latest software improves wandering. I'm a BMW Master technician at the dealership and I'm sure I've read far more bulletins, advanced information and issues regarding these vehicles and none talk about steering or wandering issues or any software updates that "improve" it.

I don't know why you're arguing? The update clearly fixed a lot of significant problems. Lane keeping assist included. Lane keeping is still active even when you don't active it specifically. So unless you entirely disable it in the menus, it's going to have a hand in pulling your car back and forth on the highway.

Also, the stock Contis really have some serious problems and really pull the car back and forth. Switching to my winters or my new ps4s tires got rid of that almost completely. So not sure whether or not you're using them or something else.

You say all this information like it's published somewhere. All I was asking is where this info is published since you seem so adamant on saying it changed. And I have an X3 M40i on Michelin PS4S 21" non runflats. I don't have any issues with steering or wandering.

It's published in the psa thread. BMW does not publish official documentation. It's pretty clear what changed, when you have a lot of people experiencing the exact same thing. It's pretty obvious they changed a lot. My car never used to lock onto lanes on my road into town. Now it does. My car used to auto shut down the engine before even coming to a stop at a light, now it doesn't. They aren't subjective things. On top of that, there are many other changes that are very obvious, like steering, suspension, etc.

So if you your car just stopped turning on, but Bmw said it was fine, you're going to agree? They released an update, it wouldn't be an update of stuff did not change.

Updates aren't always to fix things that are to be felt or seen by the customer. Every ISTA programming release every few months updates nearly every module. These updates are normal just like any Windows update you've ever done. Your car will then technically always be out of date a few months after your last update.

Updates like 20-07 brought big changes like Android Auto. 20-11 also brought improvements to things like active cruise I believe and others I forget off the top of my head that were published at least to dealer personnel.

I can't just take someone's word for something that an update changed without any documentation as placebo comes into play as well. I've worked on enough customers cars and experienced enough on my own to know some of the things that can change or not change.

Dang ya, you must be right. All those very objectively testable things didn't change in my car. Shoot, I guess my car is back to having lots of annoying issues. And here I was thinking my complaints were solved. Thanks for setting me straight.

Wrong forum then. You don't have an X3M and your car is not applicable to the potential problem.

I'm well aware I have a different vehicle. All I was asking was for official information regarding this issue and improvement. It doesn't hurt to still gain knowledge or potential issues and fixes for other vehicles. You never stop learning.

No its not. It only has a hand if you're on a painted line without a turn signal on. The wandering discussed here has everything to do with tires. I put my stock 21's wheels and tires back on a few days ago after running my 19" winters for 5 months and I noticed the wandering was back immediately. Hard, runflat, low profile tires cause it. The sensitive electric steering only makes it more noticeable.

And suspension I think. The wandering has improved for me after the ISTEP update.

Lane departure defaults to on. If you look on the dash you will see the little green light on. Unless you go into idrive and disable it. It's no where near as aggressive as turning it fully on but it still does try to keep you in the lane if you're going to depart.

I've never had an issue with the lane keep assist. I intentionally wandered into another lane to see what would happen - nothing.

Is this only a feature if there are solid painted lines?

Still want to get this update done for the reported suspension improvements but I have not run into this issue.

[Sarg33]

Just had my RIS completed last Friday. I complained about the steering assist and told them there was a March update that was supposed to address the issue. The SA told me he would look into it. When I picked up my car the SA told me he looked into it and was told the update did not include the X3M, so they did not update my software, but they did some calibrations to the system. The steering assist still seems to act the same, so calibrations did not change anything.

The software in my car still shows 11/20 as the date.

I will say when I made the trip to SC for M School, I believe going through ATL there were some Interstate portions with grooved surfaces where I felt the tracking IIRC, but that was to be expected.

As long as you're sure the alignment is correct, and tire pressures are confirmed manually with the TPMS, and you've tried Sport/Sport+ steering on those roads, suspect it may a road surface interaction rather than a primary X3MC issue. See how it plays out on a variety of routes and give us some feedback.

Same here. Steering intervention off, Conti's and steering set to sport. 4500 miles. 36 front 40 rear.

I cover all manner of highway pavement and my steering is solid, little correction ever needed. The steering assist function corrects Way more than I do. The Conti's are noticeably louder in the cabin than my Perelli scorpion's and they're definitely hard.

I got same thing on last week, alignment and 34/40 psi problem solved

[RAB1952]

Thank you, I feel vindicated. I have a 2021 X3 30i and on the back roads it is awesome but on the highway it tracks the imperfections, ruts, whatever and is all over the place. I took it back to the dealer three times and they tell me this is normal. My daughter has the same vehicle with Pirelli P7's and her's works fine. Mine has Bridgestone Dueler HP's. I also have the Advanced Driver Assistance Package which she does not, not sure if that makes a difference or not. We traded vehicles for a week and i would not tell her what but wanted to see if she noticed and she did. She says do you mean how yours wanders lol YES
The vehicle had about 2000 KM's (1200 miles) on it and I asked them to put a set of Pirelli's on it and they said NO
Had I any idea this thing would handle that way on the highway they would have had it back in a heartbeat.
I see you have Conti's on yours and it is doing the same thing, any suggestions on a fix as this is terrible, I hate it for that reason and should love it. I love my 2012 convertible that was a fraction of the price of this P.O.S.

thread revival!

changed front tyres from Conti to Goodyear and this wandering effect is still there. Istep update made no difference. Sport setting still reduces it.

anyone else found any other cures, or just need to chalk it up to the steering rack?

My problem was solved with an alignment. Guessing you've had that done already.

I find this is somewhat true. The comfort steering mode is a little nervous - setting it to sport dampens that at the (slight) expense of higher wheel resistance. Try it.
