My other half's nearly new Peugeot 2008 does exactly the same thing. I'm banned from plugging my phone in as a result.

No idea what it is though.

Is the phone attached to the radio in any way (bluetooth, audio lead)?

Does it happen with anything else in the lighter socket? Do you have a Satnav to try?

Also, see what happens when the phone is turned off, but still charging from the lighter socket.

What about if you push the cigarette lighter in to heat up? That might give an indication on whether it's just load on a circuit or some sort of rf interference.

Does it have an active antenna and, if so, where does that draw power from? I'm assuming the dab radio just plugs into the connectors that would go into the back of the original stereo (with an adapter)?

the dab radio suplies power the the dab arial via the arial lead which is glued to the windscreen so I don't think there is any connection between the cig lighter supply and the radio, or am I wrong?

do you have any other way of charging stuff from the battery (additional USB lead etc). I am thinking that if you have any other way of charging from the battery other than the cig lighter and see if that makes any difference. If the radio works its defo the lighter. if the radio plays up then its the radio (somehow)
