Dont laugh but my recently purchased 2010 TD4 HSE has developed this annoying chirpy sound,it appears to be related to the radio, and gets worse when entering a built up area
Any sensible idea what it could be and how do I remove it

Do you have a DAB radio?? Because mine makes a noise like that when the signal is weak

Chitpy, Chirpy Cheek Cheek.

sure you are not driving down the Middle of the Road ???.

Jenks, that makes sense will check tomorrow

On my MY10 car, the heated rear screen and the radio interacted rather badly to the extent that one or the other had to be turned off. Don't recall it chirping & cheeping as such though.

Sounds like my radio reception issue on DAB. Quite frankly, DAB is in a car. The main issues are mainly the very poor general coverage, but DAB is fundamentally flawed from inception as the Government only allowed a very limited bandwidth (it could then very profitably sell the extra bandwidth to other users). That same restriction renders DAB radio useless if you are used to the wonderful dynamic range of the now 'old-fashioned' FM service when using a good receiver/aerial/HiFi at home - quite frankly it's hopeless.
On my Metropolis's multi£k Meridian setup, I hardly bother with DAB out here in 'deepest' Berkshire due to constant drop-outs etc.
There you go - rant over..... I've decided to stop being a good example and will now just be a terrible warning.....
2008 TD4HSE - gone but much loved.
2014MY SD4 Metropolis - very much loved.
