Then the software is generally a bit bobbins, or maybe my wires or something. I could just about get a read in the first 10 seconds with most the software. I tried a couple of versions and a couple of different pieces of software. I've now got 5 identical files and you can read the serial number out, which matches with an old VCDS scan as well, so i'm pretty confident i've managed to back my eprom up. A WHOLE 8k file!!!
You need a fine T7 torq to get into the head unit itself and i think having the RIGHT size wire to start with would make it a fair bit easier, but in all honesty, it really isn't a job to do, unless you need to......Or you have an interest in it.

Interesting! Is this unit all part of the buttons? Is the control unit under the buttons or a separate unit?
