I don't have the details here, but I installed a VDO programable tach. As I remember it was available in a 0-4000 RPM range which is about right for an A-4. It has a hourmeter function (but mine failed just after the warranty expired) and is programable so that it can be used with a 4, 6 or 8 cylinder engine. It just takes electrical connections - one to a terminal on the coil so that it picks up a signal everytime a cylinder fires, allowing it to calculate the engine speed.
