It is an XDF file, this is a file for an application called tuner pro, which lays out a patch to make your DME virginized (fresh from factory) as well as identify VIN locations within the hex.
There is also included a Perl application that was sourced from the m3forums from user p0lar. This perl script converts your VIN number to BMW hex. This tool is needed for the process as described below.
I have also included a tool by user Marrakech from JMGarague.ru. This tool allows you to pull a full 512kb dump from your DME in boot mode as well as flash a full 512kb bin back to the DME once DME is in boot mode
Why would you want to "virginize" your DME? Well if you get a used DME from the junkyard for your 540/x5/740 it wont turn the car over due to the EWS security system. You would have to swap the EWS module the key ring module as well as the DME..... and then how would you ever get a replacement key from the stealership? This system stores a special set of codes on your DME that changes on a rolling cycle. Once you "virginize" the DME. You can now align the EWS to the DME (basically the same thing BMW does when it sets the car up from the factory). This stores those rolling codes back onto your DME and syncs the cycle they rotate on to be in time with the EWS module.
- Tuner Pro must be installed and working
- You must understand how to load an XDF and open a Bin in tuner pro
- You must understand how to pull a dump in boot mode from your DME This is outlined TONS of places on the internet
- You must have pulled a 512kb dump of your DME in boot mode
- have Perl installed you can get it from here : https://www.perl.org/get.html
- Open up tuner pro and load the included XDF
- then load your 512kb BIN you have already obtained before starting
- Once loaded click the patch at the top and click apply patch then apply
- open the 3 vin locations and the ones that show entries other than FF FF FF need to be over written with your VIN
I have included a tool written by p0lar from the m3 forums that will take your VIN number and convert it to hex
You would run this from your terminal using perl
windows:
perl vintohex.pl --vin=PUTYOURVINNUMBERHERE
linux/mac:
chmod 755 vintohex.pl
./vintohex.pl --vin=PUTYOURVINNUMBERHERE
when it returns the hex copy it and paste it into the tuner pro boxes for your VIN TADA! you have a virginized Me7.2 DME that you can now run an alignment on
