VW RCD310 Interference - 2010 VW Passat

Help needed with annoying interference problem on standard factory fit VW RCD310 radio.

Initially I thought the interference was restricted to the aux input in the central console, but this is also apparent when switching to the cd input. Basically turning the volume up creates a lot of background hiss and when pumping the accelerator causes an increasing whine.

The weird thing is I cant hear any interference when using the radio!

i‘ve taken the unit out and removed and reattached all of the plugs, which made no difference whatsoever.

It‘s got to the point where listening to cd‘s or iphone streams via the aux is unbearable, so just radio for now!

Any suggestions to fix?

Thanks In anticipation.

Remember reading somewhere that this could be caused by an earth problem. e.g. loose connection, broken connection.

Thanks, I suppose it can’t do any harm running a secondary earth cable, will give it a go at the weekend and provide an update with the results.
