My mother is trying to figure out what is wrong with her car. She
lives in a small town without an Audi dealership. And there are no
mechanics in the town that will work on one. Someone has told her it
might be the Injection Module. But she is not sure if her car has one.

Anyone know.

What year is it?
if 87-88 look here for hints

If it is diesel I think it has no module, but if it is gas........
The gas fuel injection system has many components, ECU/ECM = Electronic Control
Module is one of them. Usually they are very very sturdy and don't go bad
often.
Fuel pump relays are a possibility, or the fuel pump itself.

It has to be determined what is NOT working.
It basically needs three things:
1. Compression (timing belt has to be good too)
2. Fuel (In the correct proportion)
3. Ignition (at the correct time)

good luck!

Actually I believe it's an 86 and gas powered.

IIRC then your ECU/ECM should be inside of the vehicle under the dash on the
passenger side.
Follow the large wiring harness!

Hold a sec guys. Old injection systems are pneumatic. The injectors are
under constant pressure, provided by the fuel pump.
The suction of a cylinder during intake (on top of the fuel pressure)
overcomes the injector treshold. So far no electronics involved, but the
fuel distributor (which again has no wires). The air flow metering device
is another important part - regulating the fuel quantity according to air
flow rate - again pneumatic. The motor controller does play a part too. It
monitors the trottle position, knock sensor and oxygen sensor readings,
position Hall sensor, several temp sensors and adjusts the ignition timing
and tweeks a bit the fuel mixture. The controller is extremely reliable.
Most common problems include the fuel pump relay or the very pump, rusted
fuel lines, clogged fuel distributor, intake air leakage (cover, vacuum
lines etc). At old age there may be valve problems (especially if the engine
runs decently at high revs, but miserably at iddling.
I have found no substitute to a competent Audi specialist. You have to get
to one. Ask around your area.
Good luck
