Peugeot 508 RXH Hybrid System Repair
ElectricZentrum specializes in the repair and maintenance of hybrid and electric vehicles, including the Peugeot 508 RXH Hybrid—a model that combines all-wheel drive with diesel-electric hybrid technology, offering comfort, efficiency, and robustness. Our technical team services hybrid batteries, inverters, and traction reduction gears, ensuring the vehicle retains its original performance and reliability.
All diagnostics are performed with official Peugeot/PSA equipment by technicians certified in high-voltage (HV) systems, ensuring safe, precise interventions in line with manufacturer specifications.
Technical diagnostics and specialized intervention
The Peugeot 508 RXH Hybrid pairs a front combustion engine with a rear electric motor, managed by a high-voltage hybrid system that provides four-wheel drive. This system comprises a hybrid battery, a power inverter, and an electric traction reduction gear. ElectricZentrum performs comprehensive diagnostics on all hybrid modules, identifying communication faults, voltage imbalances, and anomalies in the electric driveline.
Common symptoms include messages such as “Hybrid system fault,” reduced electric power, or limitations in the AWD mode. After diagnostics, we define the most suitable technical solution, prioritizing safety and performance.
Peugeot 508 RXH hybrid battery repair and replacement
The high-voltage battery in the Peugeot 508 RXH Hybrid consists of Nickel-Metal Hydride (NiMH) or lithium-ion modules, depending on version. Over time, normal cell degradation leads to reduced efficiency and range. At ElectricZentrum, we carry out hybrid battery repair and reconditioning, replacing faulty modules and safely rebalancing the pack.
When needed, we supply new cell packs compatible with the original system, tested and calibrated to HV safety standards, restoring factory performance.
Inverter and traction reducer repair
The inverter converts battery electrical energy into power for the rear electric motor. Faults in this component can cause error messages, intermittent EV mode, or hybrid start failures. ElectricZentrum performs advanced electronic repairs on these inverters, replacing damaged components and restoring system insulation and thermal balance.
We also service the traction reduction gear (rear electric drive unit), replacing bearings and seals to ensure quiet, efficient hybrid operation.
Common Peugeot 508 RXH Hybrid fault codes
During diagnostics on the Peugeot 508 RXH Hybrid, the following DTC fault codes related to the hybrid and high-voltage systems are frequently identified:
| Code | Description |
|---|---|
| U0167 | Communication failure between the hybrid control module and the integrated systems interface |
| P1A79 | Hybrid powertrain does not start as expected and enters fail-safe mode |
| U12C6 | Hybrid CAN network error — invalid frame length or forbidden value |
| P1AC4 | Hybrid electric motor subassembly not activated within the expected time |
| P1B1B | Internal fault in the hybrid control unit affecting EV mode and hybrid function |
