so still not fixed. BMW says there is not a single official complaint lodged with BMW in Europe and I am taking it further. Firstly am getting an m140 pre-update transferred over for a day or two comparisons. the dealer confirmed changes but BMW will not release to them what.

had another update and setting changed in the meantime and now have baby farts and crackles fromorignal... o.k. might be able to live with but missing the crackle...

MPG (not a care with this car when bought) has gone down (so runs a lot more expensive) 13%-15% on last two full tanks of petrol ?

comfort coasting still there.

revs hanging high in sports... let go of the accelerator at 6000rpm and it will hang there and push the car for around 4 - 6 second before doing anything with the gears. accelerate again and it is irratic

lack of power on the first 30-40% of throttle and then you get whiplashed and on wet you nearly loose the car.

adaptive suspension has been confirmed as being included with this update by dealer! car is softer and "comfortable" but lacks a lot of stability as a result.

a few more points like this but I am very very very precise on the drive of my car...
have you asked for them to put the software back to how it was ? if they wont i would got to a 3rd party to put the last software back on,i know it will cost you but you can f--k the dealer off after that and go elsewhere...i would go f-----g mental at them and demand its put back to how it was.

Have requested this, and bmw Germany will not allow a lower version to go on as the updates are reliability related...

I wonder what dyno an co2 graphs would be pre and post update...

Just was amazed I am being referred to by bmw (germany) as the first official complaint who takes it further and will not rest or accept... (they had the car 4 times over a week each time now) and now getting a demo shipped over for testing.. ( will check software versions of mine and demo before judgement)

Will still have the issue of three damages to the car after the last visit there... 2 big scrapes on the bumper, door knock dent on the side, paperscuffmarks on the bodywork whee they wiped their oilfingers away 😞🥺🤦‍♀️

Hi all,

We've done a few of these software roll backs now; with people complaining the initial issues have 'ruined the car' etc.

I've driven most of them before and after, and while there is a difference - in my humble opinion it's not marked; nor is it completely detrimental to the enjoyment of the car.

I've been a bit busy recently and haven't been able to keep up with the thread.... what's the general consensus from the forum?

Agreed. I had mine updated in December and found no noticeable difference. I think the op may have another issue not related to software, cross fingers he can get it fixed.

I wonder if the OP’s car already had non standard software on it so it wasn’t a change from 1 oe program to another ?

Does the latest software on Manual M140i's still give you auto blip on downshifts when skipping gears (e.g 6th > 3rd)?

I have just had the update so I will add my opinion to the pot...

In short, I am very happy with it.

1) Engine feels stronger and more linear throughout the Rev range.
2) Gearbox, to me has improved, yes some of the artificial clunk has been dropped, but the engagement is still very positive . Downshifts also seem to feel crisper too.
3) Exhaust is more audible, I assume due to the reduction in fake engine noise.
It farts a little on most upshifts whereas it would only do it at the magic RPM’s before.
It pops and crackles the same, and it will now also crackle on the downshift at all revs. (Previously it would only do this if the rpms where under 3k)
4) steering has a little less weight in sport but to me, feels better for it.

The traction control system also seems to have been improved too, less obviously pulling power. (I will have to test this further to see if I am not imagining it)

To conclude, I had previously read this thread and was expecting the worst. I have been pleasantly surprised!

It has been weird as the overall update defiantly has one or two improvements. Is it a matter of getting used too ?

Am I going to let it be and ask dervtech to do a remote tuning and update the software?

Lighter steering, yes definitely can be nice but feel a bit light on the front now.
Sound changes, yes definitely, use Carly to switch of the fake sound or pop open the valve.
Gearbox changes, yes definitely not sure whether I am happy.... it still feel sheepish at moment or uncontrollable in a burst of power. But it is not to same every time... WHY ? It will run well on the dyno (340+ BHP stock) but feels inconsistent... tried 95 / 98 / and 102 ron petrol...
MPG not as used to be ? Even on a 60 mile motorway run it is worse ?
Traction control different yes definitely, More often have wheelspin or sliding... would actually say traction control has gone down a bit

It is now 2 months and then to think it went in for broken adaptive suspension... I am starting to loose faith in bmw to be honest and wanting to help... rather go to a professional garage who can deal with this type of car...

Marmite update!

Let me get some more miles under my belt and I will update my review.

For reference, my car was strong pre update.
It ran 400ft/lbs and 380bhp on evolves dyno.

It was the most powerful stock 40i they had tested.

I plan to take it back again at some point now I’ve had the update.

I must be confused because I thought the op was changing authorised BMW software

Here are my thoughts having had my car updated yesterday.

Overall I think it’s better than version 530.

Right then. So here are my first thoughts. 1 - It does not coast in Comfort or Sport, only in Eco Pro. 2 - Your codings will be wiped out if you have any. 3 - MPG seems a little bit better. 4 - Comfort mode appears more keen to kick down to bring the revs up to about 2000-2200 rather than using the torque as much. I assume this is emissions based. 5 - throttle response in the first 5% of the travel seems better and there seems less delay pulling off from a standstill. 6 - the iDrive software is updated and i think the house EQ curve on the H/K audio has been slightly changed. Vocals seem a little more prominent now with better stereo seperation. May be the dash speaker level has been lowered slightly. 7 - The shifts are noticably smoother in Sport and Sport+ - i personally prefer this in Sport quite a bit, i am not AS sure in Sport+ as i think it maybe reduces the "sense of occaision" a little bit. But it does mean the back end doesnt squirm about and it HAS to be kinder on the box/drivetrain doing it this way. 8 - My car seems to have LOUDER active sound in Comfort/Sport modes. I was on TL02 before.

I fail to see how BMW 'ruining' your car with a software update would be of a benefit to them... I can't even understand how this way of thinking works, please elaborate.
