With the engine off, attach a vacuum pump to the turbo actuator line. Apply 0.8 bar of vacuum. Does it hold? If it drops, find the leak.

The 1.5 dCi uses a vacuum system to control the turbocharger wastegate. A cracked hose, loose clip, or perished rubber elbow will bleed vacuum pressure. The ECU commands the turbo to produce 1.0 bar, but because of the leak, only 0.7 bar arrives. The offset error appears.

In some models, particularly those with manual transmissions, it can refer to the "Dead Point" or neutral switch circuit on the gearbox. Common Symptoms If your Clio is throwing a DF058 code, you might notice:

The "Check Engine" light, "Service" light, or the "ABS/ESP" warning lights appearing on the dashboard. With the engine off, attach a vacuum pump

Modern oxygen sensors need to reach extremely high temperatures (around 600°F or 315°C) to function correctly. To help the sensor reach this temperature quickly—especially during cold starts—the sensor is equipped with an internal heating element. When the code DF058 appears, it means the ECU has detected that this heating element is not working correctly. It could be an open circuit, a short circuit, or a failure of the heating element itself.

If left unaddressed, electrical instability in this circuit can occasionally trigger "limp mode," where the car restricts its power to protect the engine from potential damage. The Path to Resolution If it drops, find the leak

Don't just throw a new sensor at the problem. On the Clio, DF058 usually boils down to two things:
