Renault 5 E-Tech (2024–today)BehaviourUrgency: Garage soon

Sudden loss of power (limp mode) in the Renault 5 E-Tech: causes

In the Renault 5 E-Tech, 1 documented fault may be the cause: motor inverter: no-start fault and 0EN5 campaign reprogramming on the Renault 5 E-Tech (AmpR Small) engine.[1][2]

What to do now

Garage soon

Drive carefully to a safe place. Switching off and restarting may bring the power back temporarily, but the cause is still there: have it diagnosed.

What it means

The ECU limits power and engine speed to protect the engine or the gearbox when it detects a serious anomaly: turbo pressure, temperature, oil pressure or fuel. The car keeps moving, but without any pull.

Engine and gearbox faults that cause it in the 5 E-Tech

Only those that affect the versions and years this car was fitted with. Below each title, how the symptom shows up in that fault.

Other common causes: limp mode

In addition to the documented fault of the Renault 5 E-Tech, these are the most common causes in any car according to the sources.

  • Dirty or faulty EGR valve[3][4][5][6]Common
  • Faulty turbo or incorrect boost pressure[3][4][5][7][8]Common
  • Faulty air mass meter[3][4]Common
  • Sensors that are dirty, damaged or have stopped sending information[3][4][9]Possible
  • Blocked particulate filter[10]Possible
  • Other anomalies monitored by the control unit (clutch, brakes, fluids)[11]Uncommon

What to check first

  1. Look at the colour of the warning light. According to Autopista and Yamovil, with an orange light you can continue with caution, without demanding power from the engine, to the garage; if it is red, stop as soon as possible.[3][4]
  2. Avoid asking for power from the engine and do not push the car: RACE warns that with a major loss of power, a red warning light, overheating, strange noises or protection mode, you must not force the engine.[4][10]
  3. If the car goes back to normal behaviour when you stop and restart it, do not treat it as solved: Autopista warns that the fault will still be recorded.[3][4]
  4. Have the codes read with diagnostic equipment at a garage. Autopista recommends this check, and a code such as P0299 indicates, for example, that the turbo is not reaching the desired pressure.[3][7]
