How to code a used LCM with PASoft/BMW Scanner doityourself

Did I miss something? Why is LCM a big thing? Don't all ZHPs come with LCMs?

I purchased a used one as another option in troubleshooting my bulb out/fast blink problem in the event that the HID kit wired into my fog lights by the previous owner damaged the LCM I have now.

Yes they all have it but you can do some euro options with newer ones or euro ones. Also, if yours goes bad and you get a replacement, then it has to be coded to the car. As a theft deterrent, the VIN is coded into several modules of the car, the LCM is one of them...

I purchased a used LCM that I believe came off of a 325i. Would I use the "Copy FA Coding" button to get the IKE and LCM columns to match after installing the new LCM? And then code the VIN and Odometer figures manually to the LCM?

Yes, precisely.

Thanks for the input. I plan on tackling that this weekend.

Oh yeah. I forgot about your hyper flashing which would require another LCM for troubleshooting. Senior moments....

Coding through PA Soft or through BMW Scanner?

I'm thrilled that I (at this point) don't need a brand new one for $350. $45 for the LCM on ebay and $45 to Tony for the BMW Scanner interface and software and hopefully I can start making decent progress on tracking down the problem.

I have my original LCM which has 165k miles on it. I swapped in an M3 cluster and have the tamper dot currently.

i used NCS and INPA to resolve my other lights for DSC. I jjust got PASoft and found out and confirmed that im unable to write VIN and or mileage to the IKE. Reset factory default is greyed out since its not a new cluster. I assume thats why you have to swap in a new epprom so that it can be read as a NEW cluster ready for coding from the LCM.


so for now is it possible to edit my LCM to have the VIN and Mileage from the cluster to remove the tamper dot?

i did try it in PASoft and wrote VIN, mileage but still the tamper dot remained.

i read the PDF in the first post and saw that i did not do 1 thing.. I didnt change my algorithm.... when i did it however my PASoft still gave my a successful message.

There's a function within PA Soft that should allow you to copy the VO from the LCM to the IKE. Try that and see if it transfers your VIN and mileage over...

By brand new cluster, you do mean one with zero miles and no VIN coded to it, right? I think that's the only way this would work.
