I recently bought a second hand Ford Mondeo (2012) Titanium Estate which came with a Sony DAB radio.

The car battery has been flat for a couple of times in the morning - the RAC cam out yesterday and thought the problem must be the battery (the alternator was working fine, and there was no drain on the battery). Hence brand new RAC-fitted battery yesterday.

But the Sony DAB radio doesn't turn off when the engine is turned off (I thought all radios did this) and it doesn't say 'one hour mode' when turning on the radio with the engine off.

So I'm now worried that there is an electical issue with the Sony DAB radio draining the car battery - i.e. it wasn't the battery at fault, it was an indiagnosed radio draining the battery. It appears the radio isn't 'talking properly' to the engine.

Am I worrying about nothing?

Thanks,

Stuart
