[s-cars] Speed Sensor (G28) code

[Kirby Smith]

You did have the engine running when you did this test, I presume.
Else, there would be no output from the sensor.  I've seen this code
when reading codes with the engine not started.

> While using the VAG-COM, I found a DTC code indicating that the Speed Sensor (G28) has "No Signal".  I ordered a replacement part from the dealer (only $35CDN).  However, the replacement part does not appear to be a match of the part according to an engine diagram that I have in an Audi Training Service Manual for the 20V Turbo Motronic system.
