servus… yesterday my OBD2-Bluetooth-Scanner arrived to read the data and the error memory of my volvo. this here:http://www.ebay.de/itm/16105950819?… for small money a really cool part…I had already bought one before, which I would not recommend, because he had not even recognized my volvo. THIS interface even reads out the VEHICLE NUMMER automatically and recognizes that it is in a volvo S80, 2.5T. also the data are very reliable via TORQUE I just came back from a test drive. I find it impressive that you get even announced, IF the engine has reached ESTABLISHING STEMPERATURE! also the voltage of the LIMA, the PS at the mature, cool water temperature, INNER AREA TEMPERATURE, catalyser temperature, Cylinder Misfire Count, and felt 100 sensor values more, are read out during the ride and can be recorded via TORQUE. also error codes can be read out and deleted if necessary. the connection and the recognition works smoothly. the included CD with additional software you don’t really need. who is looking for something to check your car and get to know it better, is with this interface quite well served, I think. for the price of 11,50€ an acceptable compromise and certainly not wrong! I have put this article in here, because you do not fall here for the price-performance ratio sometimes, if you connect it. until now I am everyone if enthusiastic! and that, even though the product comes from HESSEN!
