My 08 xc70 is showing an image of a steering and pad lock, car won't start, what can I do?
That's a common issue with the steering column lock (SCL) on these cars. The SCL would need to be replaced, and this requires someone with a VIDA subscription as it requires a software download to the replacement module.
As a temporary workaround, try turning the wheel all the way either CW or CCW, hold it there, and only then attempt to start the car while holding the steering wheel. This workaround worked for some people.
When you have this fault, it's also possible that the steering wheel might lock while the car is in motion: understandably, that's dangerous. Should it happen make sure to file an NHTSA report!
