E30 stomp test how-to
BMW E30 Motronic Fault Codes
Procedure for acquiring error codes from Bosch Motronic DME - aka "Stomp Test"
BMW e30 s, which are 1988 and newer, have Bosch Motronic versions M1.1, M1.3 and M1.7 and can display fault diagnostic codes. Procedure for obtaining codes is:
For safety reasons, put the transmission in neutral, and turn the ignition key to "On" position but do not start the car
In quick succession fully depress and release accelerator pedal 5 (five) times
After couple of seconds Check Engine light will blink once, and start to flash code(s)
All codes are composed of 4 digits (see table below). For example, code 1211 is represented as Blink, pause, Blink Blink, pause, Blink, pause, Blink
When code(s) start to repeat, all of them have been displayed

Re: E30 stomp test how-to
someone should do a youtube video on it. It's hard to explain in words the rate at which you have to pump the pedal.

Status: HG repair. 488wtq though!

Re: E30 stomp test how-to
About half the speed you jerk off. That wasn't hard at all.
feel free to add a video though.

Re: E30 stomp test how-to
That would require a stock E30 for me to do it on. Guess I could grab the apprentice's

Re: E30 stomp test how-to
I just did the stomp test today on my e34. Worked like a charm. Check engine light came on and I used it to help diagnose yet another problem lol.

Re: E30 stomp test how-to
I havent been able to get the stomp test to work as of late... I wonder if the Miller MAF has anything to do with it.

Re: E30 stomp test how-to
The tps triggers the stomp test, check that its functioning properly. Maf should have nothing to do with it. If anything I would think the maf would throw a code the stomp test would store.
