Code your 2011.5 E90 walkthrough for windows 7 - BMW 3-Series (E90 E92) Forum

Hey Guys,

Here's a little walkthrough/augmentation to the existing docs out there to make it as easy as possible to get started with DIY coding. The steps below worked 100% for me with my 2011.5 E90 LCI 335xi, using Windows 7 on a Macbook air. I have zipped every needed file and uploaded them for you. Please read the ENTIRE post BEFORE starting. Trust me, you'll be glad you did. Links at the bottom.

WARNING!!! These steps require altering the computer in your $40k+ toy. If you are not 100% comfortable trying this, please hit your back button now. This guide is intended for people who have done a fair amount of reading into the coding process, and are completely understanding of the risks associated with coding your car. I’ve heard first hand stories about cars being bricked by not following the directions correctly or using outdated files. PROCEED WITH CAUTION!! Read, re-read, and then read again before trying. I accept no liability for anything that could go wrong. I offer this guide as appreciation for the work done by those before me who made it possible for me to recode my car. That said, it’s fairly straightforward once you’ve read enough. You can start with

The cable we used, and the ONLY cable confirmed to work is this one.
Ebay: BMW INPA / Ediabas K+DCAN USB Interface, D-CAN, CAN
http://cgi.ebay.com/ebaymotors/BMW-I...item25667c576d

Other cheaper cables could work, but I can make no guarantees. From what I understand the only cables that will work for ‘08+ are over $100.

This cable came with an adapter. I did not use the adapter on my ‘11.

I used a 2011 Macbook air with windows 7 x64 installed via bootcamp. I booted into windows 7, and downloaded and installed Windows XP Mode. Then everything else is done in the xp virtual machine.

Windows XP Mode - http://www.microsoft.com/windows/vir.../download.aspx

Then I followed xxxjecxxx's pdf. There are some tricky/ambiguous parts, so I have noted some of the steps below. Read the notes BEFORE and again as your progress through the pdf. Link below the notes.

Pdf Notes:

The first couple times running through this I think I had different language files, so I would get two error boxes popping up somewhere in the middle of this walkthrough that say something about the languages not matching with a yellow exclamation point. If these do pop up, they will pop up back to back and are normal and it's safe to close them and move past. (Sorry for the vagueness, I can't get them to come up anymore!!) If you get a different error, I would stop and ask for help.

Step 9b: For newer cables like the one above, there may only be an option to set the latency, which you want to set to 1. Also make sure it is com1.

Step 11. Connect the cable via USB first to preload the drivers. Then you can plug into the car. When you first connect the cable, windows 7 will recognize it and install drivers automagically. After that, select USB from the XP VM Window tool bar, and attach the k dcan cable. Now when windows xp sees it and wants drivers, select not this time, then install from specific location and point it to the folder where you've extracted the drivers from above.

Step 12. I have Comfort Access, so I still put the key in, but had to push the start/stop again, without ever touching the pedals, to get into the correct state, where the dash shows the key icon.

Step 13a. My ignition dot took a while to turn black but after waiting a bit I was good.

Steps 18-35. With this package, the profile is already made, which is named "FSW PSW MAN (mine)". Use this one and skip steps 18-35.

Step 36. Click File>Load Profil. Choose "FSW PSW MAN (mine)". I've read you can encounter problems if you don't clear out your FSW_PSW .TRC and .MAN files before each NCSExpert session so I would recommend doing that.

Step 53. As far as I know, always choose CAS here. This is not where you pick the module.

Step 54. IMPORTANT!! When running through this for the first time, stop here and backup your FSW_PSW.TRC file somewhere else, like the conveniently named backup folder in "Work". This will be your only way of fixing anything that goes wrong. This is extremely important.

Step 57. Choose KOMBI if you are actually doing the digital speedo. Otherwise see this spreadsheet and choose the appropriate module: https://docs.google.com/spreadsheet/...CPqY7sEC#gid=0
If you get an error here, stop and ask for help. Something is wrong.
After completing this step it's a good idea to back up your FSW_PSW.TRC file and place it in a folder named the current module you are editing, just in case you need to revert any changes you make.

Step 72. If this does not say perfect ended, stop here and ask for help. Something is wrong.

Step 73. Look at the "coding active" line and wait for "coding ended". Check your cluster for any error symbols, otherwise assuming everything worked, you're done! Just unplug the cable and the feature should be immediately active.

Fyi, for the window auto up through door open code, immediately after "coding ended" the windows wouldn't work at all, up/down, any window, nothing. Scared the crap out of me. But I took the key out, turned it off, put it back in and viola! It all worked again! including my new feature

But boy that got my heart going!
