Free Citroën DS4 Radio Code

Every Citroën DS4 from 2010 to 2018: which radio was fitted, where its serial number hides, and what we can do with it.

These screens carry no serial of their own: the code comes from the 17-character VIN of the car, plus which screen is fitted. The table below is your DS4: the units fitted, and where the serial hides on each.

Already have the serial? Type it in and we will tell you straight away whether we can answer it.

Which screen is fitted to the car?

Only needed if you are entering a VIN: the generation cannot be read from it, and each one builds a different code. If you typed a serial off the unit, ignore this. Not sure which screen? Pick the closest by year — nothing is charged either way.

That does not look like a Citroën serial — check the table below for where to find it.

We never ask for the code you are missing — only the serial.

Which radio is in your DS4?

Generation	Radios fitted	Serial	Where to read it	What we do
N 2010–2018	SMEG, SMEG+ iV2	VIN (17 characters)	the screen carries no serial of its own: the code follows from the car VIN, and we ask which screen is fitted	Free — a share unlocks it

Radio names are what is written on the fascia, not the name of the company that built the unit — a “6000 CD” or an “RCD 300” is what you see in the car. Unit fitment varies by market and trim, so treat the list as the usual case and let the serial decide: it is the serial that determines the code, not the model.
