Hello together, I have a 319 CDI box car with 222000 Km The car runs in the emergency program, the error is P124700 According to Gutmann Tester the text is: voltage value outside the target range. But it does not say which sensor is affected by it. I checked the actual values once and my charging pressure is permanently at any speed at 800 mbar. Is this related to the emergency program, or is the charging pressure sensor defective? And if so, why is it not explicitly displayed as error ? Someone an idea? Many greetings, Arne
