Throttle Housing replacement M52TU DME MS42.1

[K Mazzei]

This is on a 2000 Z3 2.8, When I replace the throttle housing MS42.1 the instructions at the end of the procedure in the BMW service manual read "Connect BMW test equipment or equivalent. Check for fault codes and clear and reset ECM memory. Reset throttle plate adaption values following on -screen directions."
My questions are
1. I have the ability to erase the codes with my generic code reader. I presume that is fine.
2. Can I reset the ECM memory by disconnecting the battery?
3. How important is it to reset the throttle plate adaption values? Is there another method to do this without access to the BMW tool?
Thanks for your time

Your generic scanner may not be up to the task. Don't really know as you will not be able to see the MDK adaptations to know if they have changed. You need a scanner with BMW software to see the MDK adaptations.

Set up INPA on a windows laptop. That will do the trick.

Using INPA to delete the MDK adaptations

• Switch off the ignition for 30 seconds.
• Turn on the ignition to position 2. Do not start the engine. Delete DME fault code memory and adaptations.
• Press the accelerator pedal to wide open throttle (WOT) four times.
• Remember that this procedure has deleted the engine adaptations, so don’t get surprised if the engine’s idle is a little off when you first start the car. It will correct itself with the first test drive.

I've just loaded it, so, please give the forum Admin a bit of time to approve it, then it will be there.
