samuel Posted July 25 Posted July 25 After replacing the knock sensor (it was probably a mistake to replace it), the engine light is still on, indicating that the problem exists. Does anyone know how to solve this?
Vauxhall Owners Club Posted 15 hours ago Posted 15 hours ago found this on a forum which may be a way forward Quote I then borrowed a more sophisticated OTOFIX OBD2 tool which found the fault codes. Deleting the codes had no effect, as the same errors appeared instantly. I then found the following two options under .... Special functions --> Service action --> Operations on faults related to self-ignition before spark (rumble) 1. "Reset number of self-ignitions before spark (rumble)" and 2. "Reset of engine torque limitation after self-ignition before spark (rumble)"
