Hi everyone, I'm new to coding and I just purchased my OBD11. I was wondering if the way you code (by myself, without the use of apps) is the same for every car/model. To explain it better: is it the same the coding for urban joke indicators or any other feature for an audi A3 and an Audi A6? Also what happens if someone calls me or internet connection fails while I'm coding? I would like to use obd11 to code my friends cars as well, I hope this devise doesn't brick or damage the ECU. Hope someone can Help me

william00 : Hi and welcome to the wonderful world of OBD11!!
To answer your first question and as a general response, the default position is that coding should be viewed as being specific to a car make and model (i.e. for a mk7 Golf).
That said, the instruction set from one car type can sometimes apply across different models (i,e, Golf mk7 and Golf mk7.5) and also across different car types (i.e. VW, Seat and Audi). Again in general, the use of the same tweak instructions across models and car make can happen when the cars have same build platforms. For example, VAG's current MQB build platform applies to many makes and models - so these cars can SOMETIMES use the same instructions. However, this is NOT always the case and care must be taken when translating instructions that were designed for a particular car - to another type/model/make.
DO YOUR RESEARCH - BEFORE making any changes to any car!! And, make sure that you have created a back-up of the vehicle's long-code/adaptation-channel database because if the lose-stools ever collide with the fan-blades (as is bound to happen to everyone occasionally), the back-up information will be invaluable!!
As to your second question - I suspect that the OBD11 software has inbuilt protection mechanisms to guard against that type of events that you identify. But again, all such protection facilities will have their limitations. Computer based devices like your tablet/mobile-phone are generally good at multi-tasking, so I wouldn't be too concerned that receiving a phone-call mid tweak will destroy a module code change exercise. But the unique aspect of OBD11 is that success with any part of its use is critically dependent on a strong and stable internet connection.
With ODB11 - many problems will be avoided if you have a good quality data-link between the main-servers back in Lithuania (I assume) and your hand-held device. This aspect of OBD11 cannot be over emphasized IMHO.

Hi Don, thanks for your quick reply and for the important information which you just shared. I can see on the forum that you have a very good knowledge in coding, Can I ask you where did you learn all this stuff or is there any website where you I can find coding options for every make/model? Thank you for your help, really appreciate that William

william00 : You have to remember that ALL tweaks are by definition unsanctioned by the car manufacturer! It's not as if any of the VAG cars that OBD11 users modify access preset solutions that vehicle designers leave available for that purpose. In truth, third-party devices like OBD11 exploit what are really manufacturing facilities that allow VAG to mass produce vehicles. So, you won't find a comprehensive list of coding changes for every VAG vehicle anywhere (and especially not from VAG, itself). In the main, tweaks get developed on forums like this by individuals which means that the mechanism for discovery by others relies on web based search engines (both intra-forum and external search engines like Google).
Occasionally, some of us have a surge-of-blood to the brain and we develop meta-posts on forums that provide an aggregated set of links to tweaks about a particular vehicle type. An example of this can be found in my local link, but there ain't nothing special about my post - you will find lots of others by using a suitable set of search terms and a search engine. As for your question about how you learn this stuff - it all starts with an interest to learn!! Not all OBD11 users have this interest; some just want to use one-click Apps - which is perfectly OK IMHO. If you have an interest, it helps if you bring to the task previous expertise in fields like electronics, car-mechanics, mathematics (yes, different numbering systems), digital theory etc. It then becomes a question about the depth of your interest - which manifests in a practical sense as the amount of effort that you are prepared to make. And finally, it also helps if your IQ sits in the 2nd quartile- at least!!
In my case, I satisfied most of the criteria above - except for the last one (but with much effort, I recently managed to record an IQ=100 - which is a personal best!! ) Don
