ZCS Structure

The 37 digit structure of the ZCS is subdivided into three segments. The segments represent specific information about the vehicle. Each segment ends with a checksum “digit”. A checksum is utilized by the coding software to detect unacceptable/erroneous manually entered coding information. The information/digits of the ZCS code reflects the options installed in the vehicle and should never be changed manually unless it is necessary for special recoding functions such as:

• Canadian market vehicle being moved to the US
• Retrofit installation of an accessory system (ie. CPT9000 phone system or BMW ULF system refer to SI B840103 & B84 08 04)

If a modification needs to be made to the ZCS structure and there is no information available in a service bulletin then the BMW Technical Hotline should be contacted for assistance by submitting a PUMA case, requesting a modified ZCS code.

Each portion of the ZCS provides specific information regarding that vehicle:

GM (Grundmerkmale) - Identifies the “Basic Features” of the vehicle and contains 9 digits that are used to describe:
• Vehicle type (E36, E38, E39 ...)
• Specific body style of the vehicle (Sedan, Coupe ...)
• Country specific coding identification (US, UK, ECE ...)
• Unique equipment that affects the basics of the vehicle (with sunroof, without sunroof, wheel size ...)
• Basic language variant (English, Spanish, German ...)

SA (Sonderausstattungs) - Identifies the “Special Equipment” of the vehicle and contains 17 digits that describe what features/functions are installed in the vehicle, such as:
• Power Windows or Manual windows
• Power Door Locks or Manual Door Locks
• Power Sunroof or Manual Sunroof
• Power Convertible Top or Manual Convertible Top
• Phone Pre-wire

The SA segment is configured to provide a total of 64 possible number combinations (option groups) for all series vehicles worldwide. The information is modified whenever
a new component/accessory is added to the vehicle via a retrofit coding procedure

VN (Versionsnummer) - Identifies the “Version Number” of the vehicle and contains 11 digits that are used to describe:
• Series specific coding data that are not reflected in the GM or

SA segments. This includes, model year dependent data, software and hardware versions of the control modules installed, coding instructions, etc.
The VN is displayed as 40 possible combinations of digits. A deliberate change in the VN will result in erroneous coding data being used when recoding a module or coding a
replacement module which will affect the proper operation of a control module(s) coded with an incorrect VN.

Note: In its original form the ZCS was displayed as a 48 digit code containing a fourth segment, the AM (Antriebsmanagement) which identified Powertrain management information specific to the vehicle, however this information was eliminated and was not needed for coding a control module.

Mine is :
GM : 819100806
SA : 20000340082FFB17A
VN : 0000000007A

its a fully loaded 2002 4.6is, missing only the rear heated seats if think. it even has double thickness windows (don't know the correct name)

Its going to be a lot of work to avoid folding the mirrors.

Bizarre, our country codes are the same...

Is it the market country or the build country? if its build, I believe all x5 would be the same

I would have thought it was for destination country but who knows...

GM (Grundmerkmale) - Identifies the “Basic Features” of the vehicle and contains 9 digits that are used to describe:

• Specific body style of the vehicle (Sedan, Coupe ...)

For the nerds like me that just obsess over this stuff I found this document.

DIY Coding BMW E46 ZCS module via NCS Expert | | Car Diagnostic Tool

So I dug into my C:\NCSEXPER\DATEN folder and found the E53ZST.000 file and found the line for SPEIGELPAKET option code 0430. The hexadecimal numbers are:

00000000 0000000000002000 0000000000

So it would be my understanding that my GM and VN would remain untouched but I would add 0000000000002000 to my SA value.

2023801100A5480F + 0000000000002000 = 2023801100A5680F

I should be able to get the ZCS option code 0430 in my ZCS list upgraded using these instructions.

As always, I am still reading and researching before I go out and start punching on keys on the computer.

Not too confident in changing this myself. Anyone else ever done this?
I did this on my 323i when I changed it from auto to manual best I remember. I have the zeko software too somewhere.

It was nerve wracking but did work in the end. Well mostly. I never finished the recoding completely because the bolts that cover the computer stuff under the hood are froze up. I didn't want to damage the box itself at the time and never got around to drilling them out or anything.

To finish the swap over I have to have it setup and ready to recode and remove the trans computer at one step during the coding and cant since I cant get to the connectors with the box lid stuck on

Found the zeko software if you still need it.
