Hi folks. I've had a few issues put right with a local specialist on the wife's A3 TDi 100. They've replaced the alternator pulley as it was very noisy, plus they've cleaned and reattached all the earth points on the car which has cured all but one fault code.

What is this component, and how necessary is it to change it?

1 Faults Found:

01317 - Control Module in Instrument Cluster (J285)

49-10 - No Communications - Intermittent

That's the radio, which has intermittently failed to communicate with the instrument cluster. Nothing to worry about in my opinion.
