A Renault Megane radio code is derived from the pre-code on the head unit label, a letter followed by three digits, or from the unit serial. Enter it on this page and the code is supplied for £19.99, refunded in full if it does not work in the radio.
Radio codes belong to the head unit serial number, not the vehicle registration or VIN.
A flat battery, battery replacement or radio removal is what triggers the code prompt.
Covers Renault Megane 2002 to present (Megane II to Megane IV).
Bob's never displays a guessed or generated code — if a working code can't be retrieved you get a full refund.
2002 to present (Megane II to Megane IV). Renault Update List, Tuner List, Radiosat, R-Link
How to find the serial number:
Try holding button 6 with the ignition on and the radio off — later Tuner List units display the pre-code.
Otherwise, extract the unit with two U-shaped keys.
Read the PRE-CODE line on the barcode label — a letter plus three digits.
Photograph the whole label so you also capture the longer serial as a backup.
How to key the code in:
Set the digits with presets 1 to 4, or the rotary control on later units.
Hold button 6 or press OK to confirm.
Wait for the unit to switch to normal radio operation.
Worth knowing:
Megane II (2002–2008): Update List unit. Card-key models still use the same audio pre-code arrangement.
Megane III (2008–2016): the head unit sits under the centre vents behind a wide trim panel — release the panel evenly, starting at the lower edge.
Megane IV (2016 on): mostly R-Link 2 touchscreens, which do not typically ask for a four-digit audio code.
On Megane II, a failing card reader or a weak battery can cause repeated code prompts — worth diagnosing rather than just re-entering the code.
Megane II and III units
A Megane II usually has the Tuner List or Update List radio in the centre stack with a separate dash-top display, and the coded unit is the one in the stack, not the screen. A Megane III often carries the Renault Radio Classic or the Carminat navigation head; Carminat and later R-Link are vehicle-coded and will not ask for a four-digit code.
The Megane is also one of the cars where an intermittent code prompt points at something other than the radio — the card reader and the body computer both sit on the same supply, and a failing battery will lock the radio long before it stops the car starting.
Removal
Megane II: the surround around the radio unclips, then the unit draws out on U-shaped keys or two Torx screws depending on trim. Megane III: the whole centre panel comes forward as a unit, starting at the lower corners.
Read and photograph the pre-code on the top label. Take care with the letter — a faded B is easily read as an 8 and that alone will produce a code the radio rejects.
Cost and lockout timing
£19.99 here, refunded in full if the code does not work. A dealer will normally be £20 to £40 for the same lookup.
If the unit is locked out, leave the ignition on and let it run down — usually half an hour to an hour. Do not keep entering guesses, because each failure extends it.
Why does my Megane ask for the code repeatedly? Repeated prompts almost always mean the permanent live is dropping — a tired battery, corroded terminals or a poor earth. Fix the supply and the prompt stops.
Is the pre-code the same as the radio code? No. The pre-code identifies the unit; the four-digit unlock code is derived from it.
Does Megane IV need a radio code? R-Link 2 systems generally do not use a four-digit audio code.
How much is a Renault Megane radio code? £19.99 on this page against the pre-code or serial, refunded in full if it does not work.
Does a Megane with Carminat sat nav need a code? No. Carminat and R-Link systems are coded to the car and do not ask for a four-digit audio code after a flat battery.
My Megane radio keeps asking for the code That is a power supply fault rather than a radio fault. Check the battery, terminals and permanent live feed before the code will stay in.
