Maybe StephenVA meant not to plug-in a scan-tool after the engine is already running (or unplugging it while the scan-tool is processing, while both it and the engine are running; both are operational mistakes that I made two weeks ago https://xoutpost.com/bmw-sav-forums/...on-switch.html.

I've learned my lesson, and will never plug-in or out a scan-tool when the engine is on, and always make sure that my battery voltage is supplemented whenever I'm using diagnostic tools.

Even if the engine is on, it won't hurt to leave a charger/maintainer still working: the alternator will not be damaged, nor will the battery, in charging at low amperage. And definitely a must if coding (something I've not tried, yet), or downloading software (on a PC or laptop, using a UPS while downloading software is a must, as is maintaining 50% or more charge level). At least that's the way trusted YouTubers do their coding or software downloading, as far as I know.

I should have used more definable terms.
Always plug in a scanner then turn the key to on or run depending on what you are seeking. Clearing codes when running leaves the car open to bricking the modules if the process locks up. Most modules will not two way communicate if the engines is running as it is a built in safe guard. Can you get info from systems if the engine is operating? YES
As posted multiple times over on the M5 forum, uninformed operators doing multiple things at one time, always have major consequences.
Connect, scan, Read, clear, then monitor systems when running. Simple

On the subject of battery voltage while scanning or coding. Always have the vehicle on a 5 amp or greater amp charger while working. Why? Because if the battery voltage drops below 10 v the process will stall. If you are coding the system it can be locked forever in between selections. Read that as bricking your module.

Bottom line: do your research first on what you are trying to do. Then proceed.
Somewhere there is a complete list of what can be cleared, modified and or selected on our vehicles.

Now I have to research where to find the Auto Unlock/lock for key fobs and the point of vehicle speed for the auto lock. Plus need to turn off the “hold lock button to open front windows 2”, as the wife manages to do this in her purse weekly on cars she is NOT or will not be driving. Welcome to the 24 pound key fob that women always seem to desire to carry in their purses then loose them frequently. Oh I mean misplaced: still in the front door key hole, left where she placed her gloves, shoes, jacket , or groceries. Why why why? It a girl thing, guys aren’t designed to know the mysterious ways a females brain works.
I personally think it comes from playing with dry cleaner plastic bags as a child. Lol

I use bimmercode for these things but I dunt think it works on e53. I got it after side grading to e70 chassis.

I programmed all our keys to roll up all the windows as well as down. I disable the panic button because you have to hold the trunk button for between 1 and 1.5 seconds to open the trunk but if you hold for 2.0 seconds it sets off the alarm!

Do you have coding option for e53? I can at least say the module name you need to be looking in because Its often not very logical.
