I wish it was as simple as the Media software, where you go into iDrive, and there's a nice little option called Revert to prior version or something like that! |

I'm just curious what happens when you go in for a scheduled service and the service dept. workstation at the dealership shows a different istep than the one on your car?

Because lets be honest, the only reason the latest "OBD tune" locked software is a drama to some is because they want to tune their car. |

The only reason I'd take a tuned car back to the dealer is to maintain the warranty service interval. There is still some warranty in tact even if they find out you tuned the car. I suppose you could take the car to a 3rd party mechanic that is BMW certified, that would solve the problem.

Mine will never go back to BMW for servicing. As I learned with my 335i tourer having all quality independant servicing kept the car in better condition and actually increased the resale value... |

Here we have an additional warranty offered by Bmw Italy for 2 years more than the legal 2 years warranty and you will keep the additional warranty only if you have all your services at BMW dealers. In addition, your used car will be evaluated more because again Bmw Italy will offer an official warranty covering used cars like the new ones (BMW Premium Selection program, 2 or 4 years of coverage depending on the age of the car), but only if the car had all the services at BMW dealers. If you don't have services at the dealer you only have a 2 years of legal warranty and your car will never enter the Premium Selection program, with loss of value on resale. Same as Porsche Approved. I know it sucks, but it's worth it. |

Yeah Ok so there's a bit of bribery there for perceived 'extra' benefits.
But you still have your 2 year warranty regardless of servicing as EU law. Lucky in UK we get 3 year basic warranty from BMW UK regardless of servicing. If you want then to pay for extended bmw warranty after year 3 then you have to use dealer service going forward. I would never sell this car back to BMW anyway who will always give you a terrible deal. I'll sell it privately to an enthusiast who understands the value of proper maintenance rather than worthless stamps from a dealer... |

So if you get your ECU downgraded to an older version to allow it to be re-mapped with a tune and then you get a BMW service and they update your software - Do you also lose the tune or just the ability to re-tune?

All tunes and any coding of relevant modules will be gone, overwritten with new standard software and settings...

No I have full dealer ISTA on a laptop at home, downloaded off the web.
Diagnostics at home FTW! After coding or mapping I always run diagnostics to check for any faults or error logs. There are literally hundreds of possible faults that don't show any dash light so you'd never know without software. |

But we don't know if this involves a DME update. Maybe they just changed some minor module.
The ISTEP is the "whole car" version. A bit like a windows 10 update to "1903", you don't know which bits they changed without further investigation.... There are 23 (approx i recall) individual control modules in the M2C, a change to anyone of those will results in a new ISTEP version. |

I just had my car in for an oil change, and no updates required. It seems like EU cars are getting all the updates. I'm sure it has something to do with the OP.

The updates are for lots of modules, not just the DME, so they will be for the US too, but just not compulsory. They won't do it during an oil change, as they won't get paid for it.
If you went in for some warranty work for example, for sure they would update the car then as stage 1 of warranty claims is "ensure software is up to date". And they'll get paid for it. I know some EU countries are calling it a "recall" and insisting on doing it. In the UK its just classed as a "quality enhancement" so you can still opt out (like I did). |
