Appropriate times to reset adaptation values

When is it beneficial to reset adaptation values??

For example, any of these scenarios:
-change in driving style
-major mods like headers
-minor mods like air intake, new air filters, etc.
-after changing sensors, O2, CPS, MAF, etc.
-after changing engine components, rod bearings, chain guides, etc.
-new engine software
-or even just to reset them every year or so to keep things healthy?

This is a question for the gurus just for the overall education of the board.

BMW typically recommends leaving the adaptation values in place for most repairs (including sensor replacement). The system will re-adjust very quickly. The exception would be any repair to the throttle system (hard parts or sensors) in which case you do need to re-set the adaptations.

I let them be unless I'm trying to track down an issue which has manifested itself as an adaptation going outside of the pre-defined threshold. These cases typically center around fuel trims and the best way to verify the repair is to reset back to zero and see how much and how fast it deviates.

I believe its good to do this after a applying a new tune to your car. Although some tuners may do this in the process. GT1 is the only way to do it outside of this correct?

I've had mine reset with an Autologic before.

So a reset after changing TPS then. Is it true that you can reset individual values? or is it an all or nothing kind of thing?

You can reset groups of values, but off the top of my head I can't remember the specific groups. I know that you can reset throttle separately from everything else and the same with fuel.

With most cars clearing codes will reset adaptations, but this is not the case with BMW. Doing a battery disconnect for a period of time (overnight) should reset them. I just use the GT1

On the GT1 it's under service functions -> drive -> DME. You can accomplish the same with any BMW-specific scanner (Autologic, Auto Enginuity, Bavarian Technic, etc)

I'm sure you know a lot more about it than I do, but I swear when I got mine reset they asked which values I wanted reset (ie. exhaust, intake, fuel, etc.) or if I wanted them all reset. I just said all..

Are you 100% sure you cannot reset individual adaptations? Even with all the different tools, GT1, Autologic, etc.?

I know that INPA can reset adaptations, but just "all" and not a subset.
