How to code the steering angle sensor to the E53
Ok, for the next guy:
If you buy a brand new steering angle sensor, it will come NOT coded for a particular VIN, or if you get a used one it will come coded for the vehicle from which it was pulled. So you have to code the new sensor to your car VIN (or re-code it in case of the used one). OK, before you electrically disconnect the faulty steering angle sensor, do this:
Ok, now that you have the contents of your original sensor's EEPROM on your harddrive, do the following:
Now, to the fun part: writing the original EEPROM data unto the new sensor!
At this point the trifecta lights will go out (hopefully to never come back!) and you're back in business! Enjoy! |
Nice. This will come in handy to many members. Thank you. :thumbup:

WORKS!
Can confirm. Did it today. This is the proper procedure to install a SAS without error. Thanks!!

This really helped me replacing my steering sensor, thanks for your post :zoom:

OK… What if you are an idiot and replace the steering angle sensor a year ago and are just now getting around to coding it?
My old steering angle sensor is gone. I cannot pull the old EEPROM data from it. Is there any way around this? Thanks in advance! |
Oh wow. Sorry to hear that. I unfortunately don't know where you could get the information to write into the new eeprom. But, I am sure it is possible.
So unfortunately, I think you'd need to take it to the dealer. The good news though is that you've done all the time consuming work, so they should not charge you a whole lot to code it. Please let us know how you get on. |
I'm not familiar with BMW Scanner and it's capabilities. I was able to code my new SAS to my VIN using Progman, which is a program that often accompanies DIS installations. Other programming apps (e.g., ISTA-P) can also accomplish it without having access to your old SAS.
