I have an 1.8T sporty A3 hatch registered 2001
Please can you tell me if it should have one or two rear fog lights.

background:
The passenger side fitting has the contact broken off but all terminals to rear cluster bulb holders have wires including one to the broken fog lamp.
Tried replacing it with full cluster and fog does not work.

(I have two reversing lights - thought it would be 1 reversing light and 1 fog
or 2 of each.)

Can't find any specs for the model's fog lights anywhere.

many thanks
