Hello,
Knowledgeable people, please help!
Car is a June 2007 3.0d SE.
Does anyone know where the RDC module/transmitter lives?
The internet hasn't provided a definitive answer and it would be great to know before removing stuff.
Grateful thanks.
Ian.

There may also be antennas in each wheel well behind the arch liners.

There is an antenna module (B46a) underneath as well.
