Also, I was also looking for a suitable OBD2 adapter to finally even read my fault memory and if necessary to delete.. Since most shops so require a pretty penny (about 25, - Euro per read) had me in the long run simply too expensive. But you can really have as much money in your workshop can for inspection, repair, tire change, etc. - Something they charge you simply still. I was so sick, I invested the money this time in its own OBD2 adapter, no matter what chip or software, It seemed to me important that the part just works and does what it should.
There are indeed a lot to OBD2 Adapter, also I was looking once helpless. Frankly, I also wanted to pay hundreds of euros because I the adapter's only privately used and probably do not need regularly. After me, this adapter was then recommended by several people in a community, I have ordered him directly to let off to give him a chance. As a software my app "TORQUE" was to recommend that there is free on Android and iOS also in the AppStore. (More to this soon) Thanks Amazon was the adapter then the very next day there and I was able to test it directly to two vehicles ...
On MAZDA 3 BK 1.6 (2004) as well as AUDI A1 1.2 TFSI (2013) was recognized the OBD2 adapter instantly without any problems.
Just in the existing OBD2 connector insert, done. At least the ignition should be on, otherwise the connection works ... ;-)
+++ +++ The TORQUE app's smartphone / tablet +++
Once the app "Torque" on my Apple iPhone (iOS 8.3) I have successfully downloaded and installed me, I have also invested directly the 14.99 euros for the full version. While the app is also available for free, but then some things must be omitted so. Those who want the full or premium version, just needs to pay the one-time EUR 14.99. So then you have the "jack of all trades": delete error codes, graphic presentations, GPS Tracker, advanced diagnostics, Upgrade Vehicle info and much more.
So, first of all you connect to via wireless with the software already installed in the vehicle OBD2 adapter. This should work without problems also usually with me it worked anyway directly right away. Then just start the app TORQUE and follow the instructions, if necessary. Still has to be elected to the vehicle manufacturers and engine type, that's it. Then are all sorts of functions directly to the selection. Reading and deleting the error memory worked for me immediately without problems, also other information from the on-board computer have been correctly read out and displayed. On the exact features I will not go into now, since it is more about the adapter to be here ...
+++ +++ CONCLUSION
So, if you include the costs of adapters and software TORQUE (premium version) together, you end up well below 40, - Euro, which is a very good price! Whether this is a "replica" of China or from wherever is. He does his thing and it's what matters ultimately. Whether because now the real ELM327 chip plugged in or not does not matter, as long as it works. For the price you should one probably not expect too much if you compare the times original manufacturer of OBD2 adapter. There probably should be clear to everyone that this is not a "premium product". Whatever - I am pleasantly surprised and am curious to see how long I'll have my joy in it. So far everything has worked out fine ...
For everyone who like me just want to read from and even the fault memory and if necessary delete., Is certainly well served here with this adapter. I can therefore say how such a case me a very strong buy recommendation! :-)
