F80 pulling to the right

My doubts here give question to the issue raised by "Rx7andy" that, once
the new Firmware is updated, just as the 5 blinks option is no longer possible
after this new update, does this Firmware update also conflict and/or
preclude the coding of the "GTS-EPS" option?


Cheers!

Sorry, I was inaccurate.
Being a 2014 production car of course I did not have the GTS/CS coding available in my original firmware.
So prior to coding my firmware was updated to latest.
What I meant is no special measures were taken to address the pulling to the right specifically. Instead GTS coding of EPS solved the problem for me.

Did you drive the car between firmware update and GTS coding? I have a 2014 production as well and the firmware update greatly improved my steering. It's getting the proper EPS patch now.
Just thinking the firmware possibly fixed the steering not the GTS coding. What do you think?

I have a 15 and went to the dealer to get the software update fix and it worked my steering became straight. Then I had coding done including GTS steering and my steering was no longer straight. The coder and I checked and the dealer had selected a "F80/F82 repair" EPS option for the fix and when we selected GTS during coding, my steering no linger was straight. We then changed the selection to F80/F82 repair again and it was fixed.

Hey,

The solution called for in the corrresponding ("SIB 32 01 17") service bulletin involved a firmware update.
Since this was issued, there have been 2 or 3 further firmware updates on top of the one indicated in that SB.

Any up to date firmware update will address and/or resolve the,"pulling to the right" issue as the module(s)
related to steering/chassis have been upgraded ("F80/F82 repair") in all subsequent updates.

"RX7andy" - I had not read your latest post:

The necessary alignment proceedures and/or readjustment of camber can, for the most part, be done electronically on our cars.

I hope this helps clear up any further confusion.

So is there any way to code in the fix? I have had lots of coding done, and if I go to get my software updated, it'll wipe out all my coding

As I said, try the GTS EPS coding.

I have the GTS steering coding. I still have the pulling to the right

As previously stated in this thread somewhere - you cannot have both GTS coding and the fix applied as they are separation options in EPS. I had this update applied and it finally fixed my pull to the right. I had to re-code my car and don't miss the 5 blinks one bit. Rather have a car that drives straight.

Here is a post that clearly shows the screenshot of the coding option.

Oh awesome! I think this is what I was looking for. Is it the F80/f82/f83 rep?

Yes - when I get some time, I may code in GTS and default to confirm the pull returns.

The dealership did this to my M4 and the pulling stopped immediately, no alignment or anything else would fix other than this software update for the steering rack:

retrofit programming as per SI B32 01 17

It is a software update but the also have to select the special conversion "steering assistance" per SIB 32 01 17 to activate the fix.

First do alignment, swap wheels, etc. then
"Program and encode the vehicle to integration level F020-17-500 available in ISTA/P 3.62.0 or later (available mid-July 2017).
Retrofit with Pull Drift Compensation (PDC) function via Coverstion-Active Steering Assistance Retrofitting."

Hey all, i?m taking my car into the dealer this week for service and want to have this issue addressed. I?ve seen a few different SB?s referenced and want to make sure i?m providing the correct one when i take it in. Could someone please share the correct one?

much thanks in advance!

Would you happen to know which I-Step you are on? I had the 58.3 update done last year, so i'm wondering if this fix will even be available in that version.

I'm on 62.x...

I believe you need at least 61.x for the repair to work.

So after months and months of troubleshooting, alignments, and programming my car is finally driving straight!
Since I did the steps in the service bulletin over a long period of time I had the chance to see and feel what does what.
Swapping wheels/tires from left to right (also brand new tires) did nothing.
Multiple alignments with different camber, toe, and caster. Yes having more negative camber on the right (positive in the left) helps "correct" the pull, I didn't want my alignment off. So we worked on caster. There's no caster adjustment with stock suspension but we were able to pull a little bit out with my GC camber plates (I mean very little). This helped a little bit but the car still pulled to the right.
August I had my car updated to the latest iSTEP but they were unable to install the EPS patch (my car wasn't accepting the software and I needed to bring it back later). Thus I drove around for awhile with the software other newer cars are coming off the assembly line. The car didn't pull as bad to the right but it needed to be "set". Like some others have pointed out, slight pressure was still needed to drive straight or I could move the wheel a little to the left quickly and it kind of sets. The whole feeling of the steering was unsettling and wasn't inspiring confidence.
Last week they did a remote programming with a BMW super programmer who was able to get the EPS patch installed. Now the car drives straight! But, and it's a big but, it doesn't feel natural. It feels like my force feedback wheel I use on my PC, artificial and numbed. I can live with it but it doesn't feel nearly as good as BMW's steering on my old E46 or my '03 Z4.
Here's my take: I think there's an intrinsic problem with the steering and the EPS is compensating/covering it up. The steering is learning your car's driving patterns and using the EPS to keep the car straight. So it's like the car is applying constant left turn pressure for you. This is all an educated guess because BMW has not and will not reveal the true problem. They just want to stop the complaints and lemon'ing cars as quickly and inexpensively as possible.
At the end of the day I'm content with my car but if I would have known the time and money I would spend on my car then I would have bought a Porsche.

Feel the same thing and can't agree more. they just did another patch to fix the problem. I suspect we got defective damper or steering rack. To me, the eps retrofit gives me straight tracking, but also more artificial steering feel, bumpy steer, and makes the car more like to follow the road crown. I even kind of feel it's worse than the fix by adding positive camber swivel bearing.

Hey,

Excellent Write up!


Thank you!

I had this problem with MY 16, and BMW is still having the issue on newer models! Unacceptable for a 78k plus car.

Correct me if I am wrong but this sib simply changes the steering programming to counteract the tendency to pull right correct? So if I had the "pull to the right" issue but my alignment was in spec there is really no harm being done, just a slight annoyance? No harm meaning the car will perform and tires will wear as intended because alignment is what actually affects these aspects and not the steering programming. Is my thinking correct?

Only time will tell. Bottom line is this "fix" corrects some "unknown" or "unreported" force that makes our cars pull right. In my case, I did all that I could to get my alignment not only within spec, but dead perfect and car continued to pull. At its worst, mine would pull to the right even when alignment spec was set to force the car to pull left. On left hand road crown, the car would still pull right.

The fact is the EPS update corrected it so something within the EPS must have been way out of whack on some of our cars. We will need to depend on those that daily their cars and have this fix to see if tire wear will be an issue. My guess is it will not be since, as you pointed out, the alignment geometry is what determine this and for me, I no longer feel the need to force the steering in one direction or another. Smooth both left and right whereas before, I could definitely say I had to apply constant left input and turning right seemed much easier than turning left.
