Is there a way to align the steering wheel after an alignment? In the service menu that’s accessible? It was just aligned and still pulls slightly to the right. So, looking to remedy that.

hahaha, i figured this is what was going to come out... The BMW dealer I bought it from did it and said they'd pay for the SC to do it, so it will go on the 16th.Nope, you will need to do alignment again or just give up (as I did)
I’ve given up to. Will forever bleed to the right.Nope, you will need to do alignment again or just give up (as I did)
Mine (QM)used to pull but service center realigned early on (almost 2 years ago)and it is gone. Tire wear is super even too. I am actually surprised how even the tire wear is. Like a solid axle Jeep. 38k now.Are any of you guys with pulling issues running DM machines?
It's not weird at all. Trying to mass produce both motors and the associated inverters that output absolutely identically is actually more difficult than you might imagine; even for a manufacturer like Bosch.Mine (QM)used to pull but service center realigned early on (almost 2 years ago)and it is gone.

What's your theory? Some QM's maybe have a motors with very uneven power curves? Seems weird for Bosch to have that type of quality control issues but maybe that is why some pull?
But you would think if it were that, why does it seem most reports are that they pull right? Would seem then just as many would pull left? Yet that is almost never reported.It's not weird at all.

Both GM and Tesla engineers feared this problem, and avoided it by using a tri-motor architecture. Powering drive wheels separately on a steering axle has long been viewed as potentially problematic.
Is this what's going on with some machines? Hard to say, hence my question.
Sorry if this is stating the obvious, but of course the majority of road surfaces slope to the right, so the vehicle is naturally going to drift right.But you would think if it were that, why does it seem most reports are that they pull right?

I get that, but I assume when people say their QM pull right they have checked the pull against that. When mine pulled right it did so on flat surface. And on crown left it would become neutral. After service center realignment it slightly pulls with crown like you are saying.Sorry if this is stating the obvious, but of course the majority of road surfaces slope to the right, so the vehicle is naturally going to drift right.
Both my QM, and the QM one of my buddies has pull left. A ton of variables at play most likely.But you would think if it were that, why does it seem most reports are that they pull right? Would seem then just as many would pull left? Yet that is almost never reported.
Mine pulled right but was corrected by service center. It seems many early units were pulling left like they were doing something wrong at the plant in alignment center. But then corrected or correctable at service centers. Then there seem some outliers that can't seem to get then aligned no matter what.
Might be. Would be good to know if any DM's have any pulling issues like you asked. I will say...my QM tracks correctly and tire wear is also very even....so it can be accomplished in QM. At least my combo of all the variable QM. Others may vary.Both my QM, and the QM one of my buddies has pull left. A ton of variables at play most likely.
Having made that statement, I am a big fan of a line a fellow engineer is fond of using; " the most reliable part you can ever engineer is the one that does not exist".
The DM eliminated a pretty significant variable. Mine tracks straight as an arrow, so is this a variable we should be looking at?
