How to find your Mercedes-Benz Citan radio serial number

Most Mercedes-Benz Citan radios show their serial on the screen, so you don’t need to take anything apart. The serial tells us exactly which code your radio needs.

Quickest way

On the screen

  1. Switch the radio on.
  2. Hold buttons 1 and 6 together for about 5 seconds.
  3. The screen shows a letter and 3 numbers (like A123). That is your precode.
  4. Nothing shows? Check the separate screen on top of the dashboard, or look for "PRE CODE" on the radio’s label.

On the label

The serial is also printed on a label on the top or side of the radio. Most radios slide out with a pair of radio removal keys (a few pounds from any car parts shop). Push them into the slots on the front until they click, then ease the radio forward. Some have screws to undo first.

Take a photo of the label rather than copying it by hand: it’s easy to mix up 0 and O, or 1 and I.

Tips for your Mercedes-Benz Citan

  • Hold buttons 1 and 6 for about five seconds. On a few radios it is 2 and 6.
  • A Renault label on a Mercedes radio is normal — the Citan is built on the Kangoo.
  • If the screen says the radio is locked and tells you to contact a dealer, it is tied to the van and there is no precode.

How to enter your Mercedes-Benz Citan radio code

Once you have your code, key it in like this. The example below shows the button presses. Your order page shows the same steps next to your code.

DISPLAY~~~~~~~~~~~~~~~~!!!!!!0000!!!!!!123456BUTTONS 1–6
Press button 1 twice for 2, button 2 five times for 5, button 3 eight times for 8, button 4 four times for 4, then hold button 6 for about 5 seconds to confirm.

Renault precode

  1. Use buttons 1, 2, 3 and 4 to set each number.
  2. Hold button 6 for about 5 seconds until the radio beeps.

If your Mercedes-Benz Citan radio says LOCKED, WAIT or SAFE

Each wrong code makes the radio wait longer before the next try, and some radios lock for good after too many. Don’t guess: get the right code first, then follow the steps for your radio.

Why we use your radio’s serial, not your number plate

A radio code belongs to the radio, not the car. A dealer usually looks it up from the Mercedes-Benz Citan’s number plate or VIN (the 17-character number in your logbook), which only works if the car still has the radio it left the factory with. Radios are often swapped under warranty, upgraded, or changed by a previous owner.

The serial number is printed on the radio itself, so the code we give you matches the radio in front of you. It is also how we can check it for free before you pay. Main dealers often charge £30–£130, and you usually have to book the car in.

Mercedes-Benz Citan radio code questions

Why is there a Renault label on my Citan radio?

Because the Citan is a Renault Kangoo with Mercedes badges, and the radio came from Renault.

Can a Mercedes dealer give me the code?

Usually yes, against the van’s number. Our free check is quicker if you have the precode.

Where is the precode if the screen won’t show it?

On the label on the radio case, next to the word SECURITY.

How much is a Mercedes-Benz Citan radio code?

£9.99 per code. The free check comes first, so you only pay once we know we can do it, and you get your money back if the code doesn’t work.

How long does it take?

Most Mercedes-Benz Citan codes appear on screen the moment you’ve paid, and we email you a copy. If yours has to be looked up by our team, we email it within 2 hours and tell you before you pay.

What if the code doesn’t work?

Check the serial first: 0 and O, or 1 and I, are easy to mix up. Still stuck? Tell us from your order page and we’ll put it right or refund you in full.
