What is OEM number 96-669-947-80 and which part does it identify?

OEM number 96-669-947-80 identifies the CD radio unit (also referred to as the radio CD player) for the Citroën C4 II (platform NC_, body code B7), produced from 2010 onwards. The unit is a PSA Group RD5-series head unit carrying the internal variant designation RD5 L3 CEM00 and the supplier reference PSA-RD530-00 / A2C53368134, and it supports USB connectivity and Bluetooth audio streaming. Also known as the radio multi display, the unit combines AM/FM radio reception, compact disc playback, trip-computer display, and vehicle settings menu in a single integrated assembly. No supersession to a higher OEM number has been confirmed for this variant; cross-reference number 96-669-947-80 (no hyphens) is the unformatted equivalent of 96-669-947-80 and is used interchangeably in PSA parts catalogues. OEM number 96-669-947-80 may fit additional vehicle models not listed here — always verify against the OEM number on your existing part or with a VIN-based lookup.

Does OEM number 96-669-947-80 fit my vehicle?

OEM number 96-669-947-80 fits the Citroën C4 II (chassis code NC, body code B7), built between 2010 and 2015 (Phase 1), across all available engine variants. The unit is fitment-confirmed for both petrol and diesel derivatives of the C4 II; engine code does not gate fitment for this part. Secondary fitment has been confirmed for the Citroën C4 I (chassis code LC) in the 2008–2011 production window, and for the Peugeot 508 I (chassis code 8D_) built between 2010 and 2018.

The critical fitment constraint for this unit is the software variant suffix. The unit carries variant code RD5 L3 CEM00; vehicles originally equipped with a different RD5 suffix variant (for example RD5 L1 or RD5 L2) may require a different OEM number even if the physical connectors are identical. PSA Group vehicles fitted with an upgraded or optional premium audio amplifier system may use a different head unit OEM number. All RD5-series units in this generation require reprogramming (recoding) by a Peugeot–Citroën authorised workshop before they will operate correctly in a replacement vehicle — this applies regardless of engine type, body style, or fuel type.

OEM number 96-669-947-80 may fit additional vehicle models not listed here. Always verify by checking the OEM number printed on your existing part or by using a VIN-based parts lookup.

Fits:    Citroën C4 I (LC_) 2008–2011; Citroën C4 II (NC_ / B7) 2009–2026; Peugeot 508 I (8D_) 2010–2018 — software variant suffix RD5 L3 CEM00 only; professional reprogramming required after installation; all engine types
Does not fit: Vehicles originally fitted with a different RD5 suffix variant (e.g. RD5 L1 / RD5 L2); vehicles with optional premium amplifier system

How is OEM number 96-669-947-80 installed?

OEM number 96-669-947-80 is a coded electronic module that requires professional reprogramming after physical installation. The unit communicates with the vehicle's Controller Area Network (CAN) bus and must be initialised to the receiving vehicle's Vehicle Identification Number (VIN) using PSA Group-compatible diagnostic software (for example, Diagbox) at a Peugeot–Citroën authorised workshop or a specialist with access to PSA diagnostic tools. Installation without subsequent reprogramming will result in the unit failing to authenticate, which prevents full functionality including radio reception, audio output, and vehicle settings menus.

The physical swap itself is a bolt-on procedure requiring only basic hand tools; however, the post-installation programming step is mandatory. After installation and reprogramming, carry out the following checks:

1. Confirm all radio bands (AM and FM) scan and receive stations correctly.
2. Confirm Bluetooth pairing and audio streaming function as expected.
3. Confirm USB playback operates without error messages.
4. Confirm the trip computer and vehicle settings menus display correctly on the unit's screen.
5. Confirm no warning lights remain illuminated on the instrument cluster relating to the audio or CAN bus systems.

When should OEM number 96-669-947-80 be replaced?

Replacement triggers

• Screen display becomes dim, develops dead pixels, or fails to illuminate on startup.
• Unit fails to power on despite the ignition being in the accessory or run position.
• CD mechanism no longer accepts, reads, or ejects discs.
• USB or Bluetooth connectivity fails persistently and is not resolved by a soft reset.
• Audio output cuts out intermittently or is absent from one or more speaker channels.
• Unit reboots spontaneously or freezes on the startup screen.
• Touchscreen or control buttons become unresponsive.
• Error messages relating to the audio unit appear on the instrument cluster.

Typical lifespan

CD radio units in this category typically last 10–15 years or 150,000–250,000 km under normal operating conditions. Lifespan is reduced by frequent exposure to high cabin temperatures, condensation ingress around the fascia panel, and heavy disc-drive use; units installed in vehicles used primarily for short urban journeys may exhibit mechanical disc-drive wear earlier than the upper mileage figure.
