Stomp Test Procedure

There have been multiple requests on how to perform the stomp test on the E34. Here it is per the Bentley manual. (According to Bentley, this is for 1992-1995 models only)

1. Turn ignition key to position 2 (just before cranking the engine)
2. Fully depress the accelerator to the floor 5 times within 5 seconds
3. The check engine light (CEL) will stay on for 5 seconds, blink off, come on for 2.5 seconds, then go off for 2.5 seconds. At this point, the fault codes will begin to flash.

If more than one code has been detected, each code will be separated by a 2.5 second pause. Edit: Sometimes if there is more than one code stored, the computer will NOT advance to the next code after a brief pause like all the write-ups and procedures say, it continually repeated the same code. If this is the case, push the pedal 5x after each code to make it advance to the next code. When all fault codes have been displayed, there will be a 0.5 second flash and then the light will remain off. To read the codes again, turn the key off and then on again. Repeat the process above.

To erase the fault code memory, first make sure the fault code 1000 (short blink and then the light goes out for a long period) is present, then depress the throttle fully for at least 10 seconds. Repeat the stomp test to look for code 1444 (no faults stored).

Here is a decent video I found on you tube of someome doing the the procedure. The code on this video is 1221.



Here is a listing of the fault codes for our OBD I E34's:

1211 DME Control Unit

I added this to my "Mechanical things you need to know" sticky thread.

maybe your light is out? :dunno: when i first for the e34 the engine light had a black tape over it so it wouldn't show. then again i live in little mexico 5 mins away from the border. sell sell sell!:rolleyes:
:confused:

well down here it is a huge i mean huge business the export and salvage cars for rebuild at the car lots here. so at times to sell sell sell and move these cars fast, they hack them to make them seem like they are running fine and once they are in mexico they don't care.:thumbdwn:

I edited my original post. The video shown is not my car. It was a video that I found on youtube. I used it because it had a code that could be easily figured out by someone watching the procedure for the first time.

Fortunately for me, there is noting wrong with my car. Sorry for the confusion.

It will not start. I have been through the entire diagnostic procedure and have ruled everything out except the DME. I'm not getting spark. Replaced the CPS with the one from my E34 and still no spark.

One caveat on the E36 is that it is a 95 model and has the EWS II which is unique to 1995. A standard red label 413 DME will not work. It has the silver label DMW for the EWS II and it is rare to find used. Even if I found one, I would likely have to have it re-coded to my car which would involve towing my car to the dealer (35 miles) and their labor at $120 per hour, even if they would agree to re-code a used DME. I have considered sending the DME to have it rebuilt at a cost of $475. It would be guaranteed for 5 tears and there would be no recoding issues since it is the one that came out of my car.

I have been communicating with Roberto a lot and he has suggested a couple of things involving either a EWS delete chip or there is a process involving a red label 413 DME and cutting a wire and bridging some other wires on the EWS module. I'm not very good with electrical issues and am hesitant to start cutting and bridging wires. There was a lot of information in the communications with Roberto and I have to really sit down and digest it.

I will probably write a nice dissertation about it once I get it resolved.

well we have dealt with two EWS locked cars both 95.
First we tried on a red label ECU to test the EWS theory. When they started, we simply cut the wires that need to be looped and do the ews delete. Since in 1995 it was still a test EWS 2 on the OBD1, and not a full one that needs to have the ring and key chip in order to start. What roberto has told you is very true. try it and you will be surprised, wire is #66 but i'm sure you know that :thumbup: (sorry for the horrible sentence i was hungry and wife was calling me over to the table so i was typing with my fist)

I'm sorry, but I'm a little confused by the run on sentence (not flaming, just not sure I'm understanding you).

I'm glad that you confirmd Roberto's assertion. I'm probably going to have to have him or someone like you to lead me through it by hand since I really don't understand electircal stuff well at all.

I don't know if it makes any difference or not, but the engine turns over fine, just no spark. Does that change your assertion? I know when I replaced the ignition tumbler a while back, I initally forgot to re-install the EWS ring and the engine would not turn over indicating that the EWS was functioning. As soon as I replaced the ring she fired right up.

i also co-own an e39 with my brother hehe... well let me look into this and discuss it with the guys here i'm sure I've heard this one before.... i have to go to work for now and have my hands full on a projector with AE i promised but after work i'll get full on to this :thumbup:

Good write up, but I just wanted to add a little something: when I had my 94 530i, it did NOT advance to the next code after a brief pause like all the write-ups and procedures say, it continually repeated the same code. I had to push the pedal 5x after each code to make it advance to the next code. I started a thread and some people agreed this was the case with their car and others didn't, so it looks like there's some inconsistency across the models. YMMV.
 
#35 ·
I believe that is code 1000 which is what must be present to clear the codes by pressing and holding the accelerator for 10 seconds.

The only thing I can think of is that your stomp succession may have been too fast. You may want to slow it just a tad and see if you get a different result. If not, then I would go ahead and clear the codes and see if any come back when you crank and drive the car again.

Hope this helps.

"Well, that indicates that you know how to do it then. It is possible that the DME has failed. Here is a very lengthy thread on the subject of EWS deletion in the 95 model.

http://www.bimmerfest.com/forums/showthread.php?t=536505&highlight=ews+delete

Again, you will need to rule out all other possibilities like the CPS, fuel pump, fuel pump relay etc., etc.

The Bentley manual has a good trouble shooting guide in it. If your brother (I think that's who you said would be helping you) is not very familiar with BMWs, you may want to try to find a good local independent BMW mechanic with a good reputation and have him take a look at it.

Good luck.

stomp test sucess

thank you steve !!!
my ride is a 09/94 bmw 530i which was gifted to me by my bro in sanfran.
after finally getting it licensed for ontario and during the first test drive the check engine light lit up. no probs says i, i have a scanner and of course it is the wrong one for the car. so a googling i go and steve enlightens me to the stomping fritz routine. sure, why not...
yup timing is everything, youtube stomping fritz routine totally rocks...
after the first stomping sequence
dash pause dot pause dot dot pause dot dot pause dot pause
repeats 4ever
until stomp again 5x after last pause
dash pause dot pause dash pause dot pause
repeats 4ever
until stomp for 10+ seconds after dot
check engine light goes to solid on state
key to off position, turn key to start engine, check light off
woohoo !!!!

Glad the information was helpful. However, did you ever investigate the root cause of the CEL? If I'm not mistaken, you show a 1221 which is O2 sensor 1.

You may want to drive it a while to see if the code reappears. If so, you will likely need to replace the O2 sensor. If so, you may want to consider replacing them both if you are planning on keeping the car for a while.
 
#53 · (Edited)
yes, thanks to you, i did discover the oxygen sensor had triggered the fault code.
yes, i am planning to keep this car 4ever.
the plan was to clear the fault and see if it kept posting.
right now i am derustifing/allmetal/por15 the sunroof lip and new gasket, then on to the oxygen sensor.
thanks for confirming that it needs two, i was not sure.
the diagram at realoem looked like there were ports after each catalytic converter but only showed one sensor floating above the exhaust system.
that confused me a bit so i was going to do a physical check this weekend.
thanks so much for making life a bit easier.

Stomp Test Question

1994 BMW 530i 4-door.

I did the stomp test. CEL blinked on and off...repeatedly. No codes displayed. Not sure if that means the car thinks nothing is wrong with it or not...but, since the car won't start, I know for a fact that something is wrong with it. :)

Now, I have to say...problems were already displayed on screen (3 total). "Low Beam" "Washer Fluid Low" "Brake Linings" The last one is due to my brother messing up the brake sensor when he replaced my brake. Brake pads are fine.

Do these existing displays hold up the Stomp test codes from displaying? Or, is my car's problem so simple that it doesnt even register with the diagnostic test? I just hope a code doesnt pop up that translates to "junk it." :)

Or, how long should I wait for the codes to start popping up. I waited 20 minutes and nothing. Maybe I have so many codes, the system wasnt finished processing them all.

Any thoughts?

I have to laugh...because pretty soon, I'll be crying. :)

Those will not interfere.
The blinking is a sequence for the code, no number will display at all.
Look at youtube videos, they will help explain the sequence.
 
#57 ·
+1 ^

The sequence of the blinking is the code. As Zombie says, watch the video again to figure out how to decipher the sequence of blinks.

You can also take a video of your stomp test and post it here and we can help you figure it out.

Yes, that may be easier for you and easier for us, explaining it is a little hard to do.
