Question - does the software (Istep) update change your DME version?

Correct. The only thing happening here is the adaption values being reset.

Car went in for a I-drive random fault and loss of some CP functionality with iOS 12.

Latest integration FW (aka I-step) updated - I-drive / CP gremilns fixed but too cold to hoon the car to see what else has changed.

Allegedly, this update re- calibrates ePAS/DSC/M-diff [a la M2Comp perhaps ?] and N55 DME and DCT module both get "refreshed" plus - perhaps the biggest win for me - the PDC beeps switch off as soon as you take it out of reverse......

My ePAS already feels fairly "meaty" - my pre LCI DCT car has MP coilovers and -30min camber correction hubs. Drive to work - after picking it this morning - was too cold/short/mundane to comment further just yet, other than to say Idrive & CP functionality - big

UPDATE:-

My initial findings of update O18184I :-

DCT - in all modes DCT feels smoother and quicker. Comfort gear changes are pretty much undetectable!

Throttle mapping - in comfort is much better than before - feels more MDM mode TBH, which I really like. Possibly placebo but it does feel more urgent low to mid range in comfort/MDM/both sport modes and DSC off.

Exhaust - overrun burbles - sound about the same but not a fan of pistol cracking / popcorn backfires TBH. MPE sounds mellower but fruitier in sport plus / track mode ie valves open.

PDC - reverse beep continues after deselecting reverse - still there !!!!

Is ISTEP and I-Level the same thing? My dealer said they updated Factory I-level to the latest version, but the NBTevo_xxx value that you can look up through maps remained the same. When I picked up the car, all the presets and other memory items remained the there.
Does anyone know what does I-level update?

If the vehicle always had the PDC turn off after taking it out of reverse, would this mean it has been updated?

I have a 2017 mid year build and it's always done this.

No complaints here

Yes they are the same. If they updated the I-Level to the latest version it should change. Mid 2018 is about the latest so if you car had one around then, there won't be an update.

Dropped my car off today and asked them to do a software update, saying that there were a few ‘iDrive glitches’. They said they found that a ‘few settings had been changed’ ala my coding of stop/start and ASD. They didn’t seem too concerned but hopefully they’ll still do the update!

Planning Istep update at my dealer. I really don’t want too lose burbles in Traction. Can someone comfirm please?

Many modules were updated. Including FEM_GW as well as the DME and DSC and GHAS (differential)

I haven't driven the car in Euro MDM yet but on regular MDM the car is much less intrusive when it comes to DSC kicking in. In addition it feels like the diff works slightly better to balance the power out. As if it's way smoother on lock and unlock, putting down power better.

Steering fees a bit tighter and there's less dampening so you feel more road which is great. Haven't tried F87CS mode just yet.

The most notable change is the responsiveness of the motor, now it feels like it just pulls, and the transition between shifts is much smoother. The throttle is way more responsive and the wastegate has also seem to be adjusted to where the car feels like it makes boost quicker. Then the pops and bangs man, sport and sport + sounds closer to the hidden traction mode. Pops and bangs are way louder.

Apple car play also seems to be more responsive, when quickly shifting between ignition modes it used to kick the phone off and it won't reconnect until after the car goes into sleep mode. Now it re connects after a brief wait and the interface is much more responsive.

Overall it's worth a shot to get the dealer to update, if anything well worth the $150 dealers usually charge.

PS: if anyone wants this done to their car I can help ya out given that you're around the OC area. You're just gonna need a spare car or a battery supply in order to give it constant power

Update 2: It seems that under certain circumstances the car goes into the ZCP/GTS Startup roar mode.. I still can't find a way to get it to reliably do it, but it's happened more than a few times already.

Reviving a very old thread - but did your exhaust still stay louder than original after your Istep update or did it eventually revert back to original volume?
Your experience sounds quite different to most others as many have experience less sound from their update!

I went from mid 2017 software to mid 2019 and the difference was dramatic. Where the traction control would step in even in MDM mode I can now get significant wheel spin and slip angle. It is way more fun.
