BMW flash code
 
Procedure for Acquiring Flash Codes from your BMW
Instructions by Ben Thongsai, bimmers.com, inc.
Note: Your BMW must have Motronic version 1.1 or higher. Motronic 1.0
cars do not have self diagnostic flash code capability (as evidenced by the
lack of a Check Engine light).
I. Determine which version of the Motronic is in your BMW by
consulting the DME Application Guide (or see table below).
II. Sit in the driver's seat.
III. Turn the igntion to the On position, but do not start the car.
IV. Immediately depress the accelerator fully and release fully 5 times
in quick succession.
V. Wait a couple of seconds.
VI. The Check Engine light will flash once, then start to blink. All codes
are comprised of 4 digits. The number of blinks corresponds to the
fault code. For example, ON, pause, ON ON, pause, ON ON, pause,
ON ON, off would be a 1222.
VII. Each four digit code will be flashed sequentially. When the codes
start to repeat, all stored codes have been displayed.
VIII. Turn the ignition Off.

My code flashes 1221 "EGO Sensor #1...the car runs excellent as normal...Is it urgent to repair this right away? What's the typical cause, defective oxygen sensor, power relay or fuel mixture/combustion problem? Cost of repair?

Hi Guys!!!
Can someone tell me if this works on the 1993 320i models and which "ON" position are you refering to? There's "On" which unlocks the steering wheel and on that allows to turn "ON" anything? So which one is it. Thanks!!!

amirboom 09-01-2011 10:09 AM

hi every one
i have bmw e36 320i 1998
i have done a huge mistake,i wanted to replace the old battery with the new one an unfortunately i reversed the pole of battery and after a min there was a mass of smoke coming out of my car.
i took it to the show room and they told me the alternator and the main electrical system is gone and i have to pay about 1500 EUR to change the mane electrical part,
do u guys know what is the main electrical part or is there such a thing in a car
couse after that accident the car was starting all the light and every thing was working but the car didn't turn on.
please help and give me some advise

nhevynopal 12-28-2011 01:53 AM

hey amirboom their are a couple of things that can go wrong first well i am not shure if the cable that does from the battery to the power distribution box has a fusable link. if it does not that's going to need a new one and then for the rest it does have them. u need to get ur hands on a wiring diagram and locate the fusable links but first see if there r some in the cable that goes from the battery to distribution box mmm 1500 euros is 2000 dollars almost r u planning on doing this ur self because other wise u pretty much r going to have to trust them on that one it sound like a right price see if they r going to replace ur battery for that price because you are going to need a new one hope dis helps

How do you erase the flash code once fixed?

Passenger SRS air bag cannot be turned off but the sensor can be fooled. Check ebay for a SRS simulator if not the fault light will illuminate and need a air bag tool to reset.
