Past 2 days, optimum quattro snow driving days, but the 90Q ended up having broken hall sender wiring. Same thing happened on my 20V, so at least I knew where to look. Dammit I wanted to blast through it like a champ

no start. ECu doesnt know where the engine is in rotation. Broke right off at the base too so I cant even solder the wires back up

A hall speed sensor determines wheel speed, so I'm guessing since there's no signal it thinks the car is stopped
Not sure what happens after that

What the heck is a "hall sender wiring" and what are the chances that it breaks in two different cars at the same time?

old Audis are weird since they have some odd choices in sensor redundancies and whatnot.

it is in the distributor, like a shutter wheel to tell the ECU where the engine position is, comes out of the side into a connector which is weak on the 5 cylinder audis. As soon as I saw the connector was zip tied in I knew what was up... the 20V happened 4 years ago, on the road too. I was able to rewire on the side of the highway on that one
It's a "Porch-uh"

The hall effect sensor that would keep it from starting is the crank reference sensor which looks at the flywheel position.

The same happened on my '98 A4 2.8L 30V (Quattro, naturally). I'm very lucky the sensor came out in one piece.
