pickie : Hi. So here's the thing -the operating platforms for OBD11 and VCDS work in entirely different ways. For regular VCDS, the user downloads the complete software initially onto his/her laptop before starting. This download contains the FULL database for every vehicle model and type with which VCDS is compatible. The download file for VCDS is about 55 MB. So VCDS users have the entire database for the product resident on their hard drive and speed of use is generally limited by the speed of communications between the laptop and the modules on the car (which is relatively quick)!! OBD11 on the other hand uses a very different set-up. OBD11 software doesn't have the same database resident on the tablet/mobile before the user starts-up the App. Instead, the APP first reads the car's VIN and then it sends a request to the mother-ship (not sure where, probably Lithuania) to download bits of the vehicle's database the first time that the user accesses a new module. To do this of course, the download speed is dependent on the quality of internet connection and on the size of the module database. So whenever the OBD11 user accesses a vehicle, a wait time results and whenever the user accesses a new module for the first time, a wait time results, and whenever the user accesses a different part of a module FOR THE FIRST TIME, a wait time results...... etc. The database that eventually is loaded onto the tablet/mobile phone from this process resides in memory cache (cache size permitting). Mercifully, this means that within a diagnostic session, the downloaded database can be accessed quite quickly multiple times. However, once the diagnostic session is terminated, the downloaded database is lost and the remote download process must commence again the next time that OBD11 is used. That's why "it take so long for it to connect" Don PS: an interesting consequence of the OBD11's way of allowing user access to its software is that it is far less prone to piracy. Because OBD11's database is safely locked behind the corporate fire-wall of the mother-ship and is only accessible through a remote request - VOLTAS IT can precisely manage who gets access to their IP and for how long this access is permitted. This is IMO a very cunning (and very effective) way of securing the value of OBD11's product from IP theft. The VCDS approach is far more prone to piracy because their IP is entirely distributed to the outside world (and is therefore "hackable"). Again IMO, that's one of the main reasons why there are so many fake VCDS cables and there are NO fake OBD11 devices- I reckon!!

Mine takes long each time I use it and it is the same car each time
