Astra spanner light

[Indyi]

Hello people
Vauxhall astra 2009 1.6 petrol has an issue the car spanner light comes on sometimes. I know this means a fault and have done the pedal test no codes. I have even connected a pro torque reader showing no codes. Any ideas why the light is coming on

No not the sevice light. This light has the spanner going through the roof
