VW Passat Speedo Problems...
As I was discussing with some of the fellas over lunch today, the speedo in my Passat was going haywire last night. This morning it just fell dead. The digital odometer still displayed but didn't register distance traveled.
The speedo on this car is both electronic and mechanical. Exiting the tranny hump, there is a small port in which a speed sensor plugs into. Inside the port are small plastic worm gears that turn with the tranny and turn a gizmo inside the sensor. The sensor then sends the signal to the ECU which runs the speedo, odo, door sensors (auto-locking doors at 15kmph) and other ECU functions (like avg speed and fuel consumption displays).
Replacing the sensor will be a royal pain but at least it will be inexpensive.
I will, however, be picking up the Bentley manual on CD... the Miata books are dirt cheap compared to these bastards!
