This is your mechanical fault light and the lack of power is the car going into limp mode to protect the engine and its components.
Have a garage run a diagnostic check to find the fault code and the fault.
Hope this helps

The problem is in the loom in the steering wheel, it requires removal of the airbag and a new wheel loom to be fitted. The loom costs about £15.00 I think.

Some cars with an ecu have a default setting whereby they run but only at idle. Go to your local Vauxhall dealer, look sweet and ask the service people if they can offer any idea, I mean the mechanics not the counter staff who generally don't know a handbrake from a halfshaft.
Or go on line and scour the astra owners helplines to see if its a common problem.
Don't spend a penny in a garage without checking all possible areas first. Like the other answer, it may just be a cable or electrical plug come off.
