Update for Engine Control Module. Should I Update?

The BMW dealer says they have an update for my CPU and its going to cost me $140 plus tax. They say it will fix my idle surge I have on cold starts. I asked if it my tweak or make anything better performance wise and he said no it will probably take some out. I am like what?

What do you guys think?

You could go the dcan cable route and do it yourself although some people deem this too risky. I personally have been successful and recovered from unsuccessful flashes

It was actuall that I went in and they told me update available. Some people say it will fix the idle. Is this true? It surges on startup warm or cold. Bone stock. I message you the last 7 of vin.

Here is the paper from the dealer.

Also when I turn my wheel and let of the brake if I don't touch the gas the idle starts jumping.

current car software version : E89X-10-06-501 ( about 3 years old )
Last know service milage : 102.133 km about 63500miles

Car needs update to newest Ilevel software due to possibly injector problems , instrument clusters failure due to to high voltage on fusebox and A/C flaps restart continoulsy, Cold start time should be reduceds plus idle will be up about 50rpm - info from my friend from BMW AG Munich

My software tells that you dont currently have any pendings Service/Technical Actions planned by Stealership

Thanks buddy! Does this mean I should get this update and that it should fix the idle fluctuations?

Its always worth to have newest possible software, all depends on price actually 140$ just for engine is quite a lot but if its only way for you - go for it!

I doubt it'll be just the DME update. ISTA/P will want to force update all control units installed in the car. So basically, the entire vehicle will get a software update for $140, which isn't too terrible.

Dracon is definitely right. Stealerships use Ista-p and they don't encode individual modules like Winkfp can. They must code the entire car

Can I get such details about my car? Just interested to see if it needs work and don't want to pay the full service inspection at BMW for $200.

I just realized that he instructed me that the update fixes possible injector problems and now my car has got some issues is far as misfiring. Could this be the reason?

The dealer put me in a loaner car saying it will take 3 hours. Wow.

Will this update make my exhaust quieter? I hope not.

I just got my DME updated at the dealership, and my exhaust got quieter. Yesterday I had my secondary cats cut off and I love the way it sounds, now it sounds like crap.

I do I fix this, or get rid of this update?

Also idle isn't as smooth and my sputter has returned.

I am providing pictures of my update to see what software version I have and if you guys can tell me anything about it.


ISTA/P version - 50.4.002

Integration level - E89X-13-07-503

I'd bring the issue up with your dealer.

They will not be unable to remove the software update, their systems don't allow anything like that. You'd have to find a aftermarket coder to reflash the DME with the original software.
