it will not scan older Mercedes said not equipped on most and will not read faults on some benz and jag it shows a fault then press read fault it dose nothing all the other options work but not the read and some test don't work like for instance a 2009 r350 Mercedes benz would not level rear air suspension the f3 would press but nothing happened luckily my shop has autologic when the maximus dose not work
Yeah after 6 months of ownership, I'm not too happy myself. I work only on German cars, and it is hit or miss. BMW, and VW work great, Benz, Jag, Fiat, Rover is terrible. I dunno how much of it is Launch itself, or the actual hardware. The android platform is atrocuous .
