    hi. i just fixed my airbag light (seat belt tensioner broken wire) and reset using inpa. while looking through the inpa functions i found rest adaptations. decided to reset. upon pushing the reset button the engine sound changed/ revs dropped slightly. looked at the smooth running again and the cylinders seemed to be running more evenly. decided to go for a decent wee run and found the car much more responsive. was bogging down a little at low revs previous to my meddling. can anyone explain this.

    It is a good idea to clear out the adaptations every year or so, or after a big change such as the 02 sensors, spark plugs, full service etc. If yours haven't been done for years then they were overdue.

    You should only rest the adaptations with the engine off. Expect lumpy idle for the first 80-100 miles.

    thanks for your reply. as a complete novice with inpa do you know if there is any sort of operating manual i can download. i reset the adaptations with the engine running and heard the engine note change slightly.the car is running much better but i just hope all is okay . was using inpa ro reset my airbag light and as usual i had to have a nose through the other menus. airbag light reset successfully. i did the smooth running test and cylinders 135 were slightly rough whereas 246 were really smooth. after the reset adaptations all cylinders were even and smooth. truth is i was used to tinkering with points and plugs before i got my first BMW. i have owned a lot of cars in my time but don't think i will buy anything other than a BMW again. i just love driving it. i only hope i haven't broken it with my lack of brains and too much enthusiasm . cheers

    Resetting the adaptations might cause the valves to have an issue such as touching the pistons or something, or cause the engine to run very lean for a few seconds creating hotspots in the chamber I don't know I'm just guessing. It'll also confuse the engine on a drive by wire car that expects the Throttle Body to be closed when the adaptations are reset, of which your E36 isn't.

    Whatever the possible issues it's done now and it didn't explode. If you are happy with the way it's running either stop fiddling or reset the adaptations with the engine off and put the laptop away until it goes wrong again.

    Can you reset adaptation values with DIS as well, or just INPA?
    There are only two products required to make the universe work properly: Duct tape and WD40. 


    If it moves (and it shouldn't): duct tape. 
If it doesn’t move (and it should): WD40.

    Everything else is just stuff.

    search "inpa" on ebay, seller is something like bm-cables . £24.99 and you get everything you need, including inpa, Dis v57 and SSS v32, TIS. however i cannot make my cable connect to the SSS.

    mind you, unless you get a proper ADS interface, you won't be able to connect to all modules in the car. But you will be able to connect to the DME and read and delete errors.
