Description
CD radio Siemens VDO for Citroën and Peugeot vehicles. The radio must be coded to the vehicle using diagnostic equipment.
OEM-style RD03-01 CD radio designed for a range of Citroën and Peugeot models. This unit is a direct-fit replacement for original factory radios fitted in many Stellantis vehicles and carries common OEM reference numbers used by workshops and DIY mechanics when sourcing spare parts. Ideal for professional garages and competent DIYers who need a reliable, factory-compatible audio unit with CD playback and standard radio functions. Note that after installation the radio requires coding/registration to the vehicle to restore full functionality.

Function And What It Does
This unit provides AM/FM radio reception and CD playback in the factory dashboard slot. It interfaces with the vehicle’s audio wiring harness and antenna and is designed to work with original steering wheel controls and vehicle speakers when correctly installed and coded. Some factory features (e.g. steering-wheel remote, RDS, display language) may require proper coding to be fully functional.
How To Replace
- Always disconnect the negative battery terminal before starting work to prevent short circuits and preserve vehicle electronics.
- Remove surrounding trim panels using appropriate trim tools to avoid damage to clips and finish.
- Extract the radio using the correct removal keys or by undoing the mounting fasteners.
- Carefully disconnect the wiring harnesses, antenna lead and any auxiliary connectors. Inspect connectors for corrosion or bent pins.
- Fit the replacement unit, reconnect all plugs and the antenna, then test electrical connections before reassembling trim.
- After mechanical installation, code/register the radio to the vehicle using PSA diagnostic equipment (DiagBox/Lexia) or an equivalent service—this step is required to restore full operation.
Installation Recommendations
- Use manufacturer-specific removal tools and avoid excessive force on plastic trim.
- Check and clean connector contacts; apply dielectric grease to prevent future corrosion if appropriate.
- Verify power supply at the radio connector (constant 12V, switched ignition 12V and ground) and antenna continuity before assuming unit fault.
- Do not connect or disconnect radio connectors with the battery connected to reduce risk of damaging the unit or vehicle electronics.
Why The Part Most Commonly Fails
- Mechanical Wear Of The CD Mechanism: Repeated use and age cause loading/tuning mechanisms or laser assemblies to degrade.
- Corrosion Or Poor Electrical Contact: Moisture ingress or dirty connectors can cause intermittent power or signal loss.
- Power Supply Issues: Blown fuses, faulty ignition-switched feed or poor ground can make the radio appear dead.
- Software/Pairing Lock: Factory radios in PSA vehicles often need to be coded to the vehicle; a unit removed from another car may not operate until coded.
- Internal Component Ageing: Electrolytic capacitors and other age-sensitive components can fail after many years in service.
Quick Workshop Checks
- Check fuses related to the radio and central electronics.
- Measure 12V on constant and ignition-switched pins at the radio connector and confirm a good ground.
- Inspect the antenna lead and radio signal with a known good head unit to rule out reception issues.
- If the unit is powered but non-functional, consider coding/registration and verify connector pinouts before replacing.
Compatibility Notes
Part numbers listed above are commonly used when ordering this radio. Always confirm part numbers against the vehicle’s original unit or parts catalog. This radio is supplied as a direct replacement for the referenced models but requires diagnostic coding to the vehicle for full functionality.
