On my vRS Fabia, when the stereo volume is at '0', engine off (haven't actually driven anywhere other than from the dealer due to illness this week!) there is quite a loud 'hisssss' from all speakers, whether playing a CD or on the radio tuner mode. (It has a CD changer as well but haven't tried this yet).

Anyone else come across this and/or a fix/pointers to the problem (just to give me some ammo for the dealer next week).

Cheers,

I'm surprised you get hiss when the engine is not running – is it “an ear next to the speaker” quiet hiss or “can hear it half a mile down the road” really loud hiss?

If it is loud, the car is new and the stereo or wiring has not been messed with then I would hassle the dealer. The stock unit is not brilliant, but it should be quiet at zero volume.

It sounds like a fault with the HU IMO - It seems to be sending out strange signals to all the speakers... If it was just one doing it perhaps it would be different...?

:confused:

This is the sort of worst scenario why I've never kept the standard HU's for that long and upgraded as soon as I could. I wonder if you can ask for a car to come with no HU at all... just the connectors?

Sounds like poor grounding...get your dealer to fix it...
