Hoping someone in here could help me. I have a 2005(05) A3 2.0 T FSI Quattro S Line and need to connect the speed pulse to the already installed Pioneer AVIC X1BT.

The local car-audio guy has indicated that it may not simply be a case of locating and connecting the wires, but installing another component, which costs approximately Ł100.

Can anyone help me on this? Will I definitely need this Ł100 part or is there a way around it?

Appreciate any help or input.
