Speed sensor (vss).

Classic symptoms.

The radio volume thing is caused by what is known as the AVC, (the radio gets louder to overcome road noise and is dependent on a signal from the VSS to function).

Until you get the VSS fixed you can go into the radio menu and set AVC value to 0.

A new sensor isn't expensive but removing the old one can be a bit of a chore.

A new locking pin is essential as the old one will definitely not survive the procedure.

Everything you need (and cheaper than from Ford)-
