Volvo-Modelle, für die dieser Fehlercode gilt
Gilt für folgende Modelle:
4 ModelleS80 (2007–), V70 (2008–), XC70 (2008–), XC90 (2003–)
Was bedeutet der Fehlercode?
This code is event-based and linked to an algorithm. The engine control module (ECM) compares the lambda values of the cylinders in bank 1, cylinders 1 to 3, and cannot even out the difference with individual cylinder lambda control, since the deviation is too large. The cause is mechanical and lies in the engine.
Mögliche Ursachen
- Mechanical causes in the engine
Was Sie tun können
- 1There is no fault-tracing for this code; it is an event code that shows the control range has been used up
- 2Read and note the fault code, and clear it if needed
- 3Have a workshop with diagnostic equipment examine the mechanics of the engine for cylinders 1 to 3, for example the compression
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
Was der Fehler beeinflussen kann1
- Individual cylinder lambda control is switched off
Allgemeine Hinweise für Fahrzeughalter. Die Diagnose am Fahrzeug kann eine andere Ursache zeigen.
