Description
Overview
This is a used Sahara control relay manufactured by Bitron or Omron, compatible with Citroën & Peugeot vehicles. The unit is supplied with a short section of wiring harness (pigtail) to simplify replacement and reduce installation time. It is a practical, cost-effective spare part for professional mechanics and experienced DIY enthusiasts.
Function
The Sahara control relay switches and manages electrical power to the vehicle circuit commonly labelled as the “Sahara” system on PSA group wiring diagrams. Depending on the model and specification, this relay can control auxiliary circuits linked to heating/ventilation or other related electrical loads. Its role is to provide reliable switching of higher currents while being driven by low-current control signals from the vehicle ECU or switches.
Fitment And Compatibility
Mainly fitted to PSA Group cars such as the Citroën C5 (X7) and a range of Citroën and Peugeot models that use the same relay part numbers. Always verify compatibility by matching the part numbers on your original relay or by checking the vehicle VIN with the parts list. This listing covers common reference numbers used by dealers and workshops: 250030, 220506, 6545XF.
Installation
- Disconnect the vehicle battery before starting work to avoid short circuits.
- Locate the fuse/relay box where the Sahara relay is mounted (consult the vehicle manual or workshop manual).
- Unplug the relay connector and remove any retaining clips or screws.
- If the supply includes a wiring pigtail, attach the pigtail to the vehicle connector or existing loom as required, then plug the relay into the fuse box.
- Reconnect the battery and verify operation of the controlled system; check for fault codes or unusual behaviour.
Common Failure Modes
Relays typically fail due to contact wear, internal welding from high current surges, corrosion in damp environments, or degraded internal coils. Symptoms of a failing Sahara relay include intermittent operation of the controlled system, no operation at all, or electrical noise and blown fuses. Replacing the relay and ensuring clean, secure connections usually resolves these issues.
Condition And Quality
This part is offered used and is supplied with a length of wiring to assist installation. The unit has been inspected to ensure correct electrical continuity and fitment. Suitable for mechanics and competent DIYers who need a reliable replacement at a lower cost than a new OEM unit.
