I am searching for the best way to reset my ECU on a 2000 GXE. I see a couple different ideas:

Pulling MAF Fuse: But which one is that?
Unplugging the battery: I did that all day and nothing.

Help?

Suggest getting the code(s) read first, then cleared by an OBD II unit. Depending upon the code, some will re-trip instantly if the problem(s) are not corrected........................

Without OBD II reader:
pull battery cables and remove hazard fuse. let sit for at least 24 hours to reset.
With OBD II reader (best way):
OBD II scanner, read code, then delete code.

Yes, suspension should be first. I quote BMW by saying "Power is nothing without control"

Which is the MAF fuse? None of them are labeled as a MAF fuse.

ok, I found a way much easier for you, since after searching for awhile I think it is not possible for you to manually reset your ecm, or at least it seems other people with 1.8's have trouble using the pedal method. just take your car to auto zone, checker, anyplace like that and have them scan your codes and delete them as well. it is free!

Also try this method. I know it works on the QR25 but I dont know about the 1.8

SES Light Reset procedure

This is how you reset the check engine light. No tools required!

In car ECM Diagnostics/ECM Reset procedure:

1) Sit in the driver's seat.
2) Turn the ignition key to the ON position and wait three seconds. (Do not start the car.)
3) Fully depress and release the accelerator pedal five times in less than five seconds.
4) Wait exactly seven seconds. Fully depress the accelerator pedal for ten seconds until the MIL light flashes.
5) Release the accelerator pedal and start counting flashes to obtain the four-digit trouble code.

Long flashes (0.6 seconds) indicate the first digit of the code; count the blinks one through nine and write down the first digit. (Ten blinks indicates a zero.)
The next three digits follow in turn in the same fashion except with faster blinks (0.3 second) and a 1.0-second pause between digits.

The ECM code repeats intself until you turn the ignition key to the OFF position, at which point the ECM resets itself to standard get-in-and-drive-the-car mode.
You can look up the trouble codes in the ESM/FSM; there's a bunch of them. In the ESM, refer to page EC-639.
Additionally, if you get four blinks of ten (0000), the ECM is indicating no malfunction.

You can clear the code (and the annoying MIL) by holding down the accelerator pedal for more than 10 seconds while in Diagnostic Test Mode II. When you release the pedal, the ECM erases the trouble codevd

Yes, suspension should be first. I quote BMW by saying "Power is nothing without control"
