Techinical Info
The component with code OE 296052118R is a DC-DC voltage converter installed on the electric vehicle Renault Twizy. This module converts the traction battery's high voltage (about 58 V) into the 12 V required to power all the vehicle's auxiliary services, such as headlights, instruments, fans and electronic control units.
It is integrated into the vehicle's charging system, but also operates while the car is in motion, maintaining a constant supply to the low-voltage network.
Component availability
The converter is available as a new part or in a refurbished version.
DIPA is able to refurbish the module by replacing damaged internal components and restore it to full efficiency.
Defects and common problems
The OE 296052118R converter is known to be prone to recurring failures, which can appear in several ways:
- Illumination of the STOP warning light on the instrument cluster
- Activation of the 12 V battery warning light
- Sudden shutdown of the vehicle or interruption of charging
- Voltage fluctuations on the 12 V line, causing malfunctions of connected devices
In many cases the fault is intermittent, but it can progress to prevent the vehicle from starting.
Typical causes of the failure
The main causes of the converter's malfunction are:
- Thermal stress due to heat generated during operation or charging
- Failure of power electronic components inside the DC-DC module
- Defective cooling fan, which impairs heat dissipation
- Oxidation of connectors or breaks in power and communication wiring
These factors lead over time to degradation of the internal circuitry and loss of stability of the output voltage.
Operational symptoms and implications
When the converter is faulty or defective, the vehicle may exhibit:
- System alarms and limitation of electronic functions
- Irregular starts or inability to power up the instrument cluster
- Abnormal behavior of systems powered at 12 V (headlights, wipers, fans)
- Sudden stopping of the vehicle under low load conditions or during charging
If not resolved, the problem can compromise the safety and full functionality of the vehicle.
DIPA recommends a professional diagnosis, which is essential to confirm the specific fault and plan the correct intervention.
Conclusion
The OE 296052118R DC-DC voltage converter for the Renault Twizy is an essential electronic component for the operation of low-voltage systems. Failures of this module are fairly common and can affect the vehicle's daily use.
