My daughter's 2001 New Beetle had a working speedometer and tachometer this morning on the way to school, and when she started home they were both dead. The speedo is at 0 and the tach at around 1000 RPM. The gas gauge may be working, not sure, but all LCD display functions are okay - odometer is fine, trip miles, shift indicator, etc.
What is there in common between those pointer-based gauges that could fail at the same time? I'm assuming each is based on an electromechanical sensor and provides a signal to the instrument panel, but I would think the speedo comes from a wheel and the tach from the engine.
Any suggestions on where to look, in the hopes that it's a loose wiring block or something else simple? A fuse, perhaps? Sure hope I don't have to replace the whole panel. Thanks in advance for any suggestions!
