Hello guys, got my a3 loving it but I have a couple of questions; What's the deal with computer 1 and 2, why have 2 mpg read outs and 2 fuel range and everything, am I missing a trick with this stuff? What's ECON and what's the A with an arrow round it? One is aircon I assume! How much would I be looking at to convert to double din? Excluding the radio and labour? Is the windows up and down on the key standard? Where might I find an ignition fuse to pair to my radio for ignition live? That's all for now! Thanks very much!
