[type-44] where is the speedometer sensor located?

Hi Richard!

There are two possibilities:
a) You have an Audi 100/200/5000 before 1/88: Than you don't have an
electronic speedometer.
b) You are looking in the wrong place.
Apparently a) is easier to fix: Just buy a nice 200 20V!
Ok, now for b):
Open the hood, stand before the car. Look down right beside (not left
beside) the engine.
See the drive shaft to the driver's side (on left-hand-drive cars)
wheel? At the end of the gearbox, facing towards the shaft, there is a
black plastic thing standing pretty straight up with a cable at its
upper end. That's the sensor. Take off the cable and do a difficult
push-turn-pull action on the sensor to get it out. There should be a
"lever" on it that allows you to push and turn more easily, if I
remember correctly.
 
In case your speedo needle bounces up and down, there are basically two
main reasons possible:
Badly soldered points at the electronic board or the missing of enough
grease in the gears of the speedo. I have never heard of a speedo-sensor
failing, but with Audi's electric/electronic sicknesses, I would believe
anything.
