VW Code 06686
06686 Description And Summary : |
|---|
The instrument cluster alerts the driver to the fault linear oxygen sensor exhaust bank 3 / reference voltage, open circuit the system depends on oil pressure to switch between cam profiles fuel pump "b" control, circuit / open you can see the temperature sensors for drive cycle radiator exhaust (g382), signal too largely will delay your vw fault. |
06686 Possible Causes:
06686 vw fault code may be caused by one or more of the following:
