I have asked this question before on here and did not get a response. Hopefully rephrasing that question in order to clarify what information is being requested will be the factor that gets my question across to someone out there. I have made a few adjustments/modifications/tweeks whatever term you may use. Under each module you have 3 main options for you to consider Long Coding (nowhere near there yet). Adaptations and Basic Settings (where I currently sit) Under Adaptations and Basic Settings you are typically askd the choose a channel ranging from 0-255. Considering that my typical work week consist of anywhere from 50-70 hours a week doing construction work in the hot Texas Sun. I rarely have the energy or time in order to go through 255 channels for every module in order to determine which ones are null and which are valid. Surely I am not the first guy on here that has not either asked or answered this question. More than likely my simple ass does not know of some chart that is already available giving all this information, just sounds like something that is right down my blvd of bad decisions

mpncoco : Hi - very good questions How hot can the Texas sun be - surely it can't be hotter than the blistering heat here in the very deep south? And as for spending 50-70 hours on construction cites - been there, done that and I can tell you from hindsight that it ain't worth it (regardless of the money that someone throws at you). As you will learn later in life - there are much more important ways to spend these years! But enough of my gratuitous comments about non OBD matters (you didn't ask about these things)...... I get a sense of frustration in your words! Please don't take offense - but I suspect the real issue in your case is one of managing expectations
Now, let's talk about modules: there are ostensibly two types of modules from the perspective of diagnostic devices like OBD11. The delineation between these types is the generation of modules called UDS/ODX which basically introduced a communications protocol known as "CAN". In UDS modules, stuff like adaptation channels are identified by actual written words!
In your instance and whilst you haven't disclosed the model, or car brand, it sounds like your car uses pre UDS protocols (because it uses numbers to identify the adaptation channels). So, I assume this is an older car - maybe?
So, here's the thing about the entire third-party diagnostic industry that focuses on the VAG range of vehicles - it's really not supported by VAG AG - meaning that it's tolerated (to a degree), but it's actually not supported (VAG have developed their own diagnostic device called "ODIS"). In particular, the big issue for VAG is Intellectual Property (IP) which is a valuable thing and there has been lots of effort and money spent to ensure that IP is retained by the car designer/manufacturer.
I'm not sure how VOLTAS IT (the parent company for OBD11) operates, but the official blurb announces their special license with VAG. Nevertheless, it very much seems that the OBD11 IP boundaries are the same as their competitors with respect to disclosure of module database!
Why am I telling you this - I hear you ask? Well, I'm trying to emphasize that the information that you seek (being a decoding list of adaptation channel numbers and their purpose for every pre UDS module) lies behind the IP fire-wall. The only information that is in the public domain is stuff that has been discovered by folks like us on forums like this!!
I don't in any way condone industrial espionage (because I firmly believe that IP belongs to the original developing company) - but I'm sure that there would be many in the outside world that will enjoy getting access to the database in these modules! My advice - don't hold your breath for this outcome!
Yes, I understand that this is not what you want - but alas this is reality!!!
Don
PS: Why is the long-code string scarier than the adaptation channel database on non UDS modules? I would have thought the opposite because there are lots of descriptors for the software switches in long-code and each BIT only has 2 x states (unlike channels)!

mpncoco not a direct answer but may be of some interest / help this is a backup from control unit 09 on a 2010 golf showing the list of adaptation channels that appear to have an active value so do a backup on your car and check the output Adaptations: Channel 000: 2 Channel 001: 5 Channel 003: 1 Channel 004: 0 Channel 005: 0 Channel 006: 1 Channel 007: 0 Channel 012: 1 Channel 013: 0 Channel 014: 200 Channel 015: 200 Channel 017: 1 Channel 018: 1 Channel 019: 0 Channel 022: 0 Channel 025: 15 Channel 029: 0 Channel 031: 3 Channel 032: 0 however if you select channel 3 in the adaptation option you will see its has a label " selective door locking " and has two values 0=all doors or 1=selective door locking
Currently I am not aware of a way to easily extract all the labels from OBD11 but if you search for VCDS Channel mapping on your motor you may find some info on older cars. VCDS have now encrypted there info to stop this sort of sharing but there are still some good people who spend the time to share the stuff they find. With regards to OBD11 These labels are maintained (well more likely created and then forgotten) by the user community so they are not always correct. With regards to basic settings afraid its a channel by channel review as far as i can see one other thing as you can see below if you just touch the drop down list arrow you will see a list of all the created labels
hope that helps a little
