Engine warning lights - Astra 1.8

My friend has reported a problem with her car. Vauxhall Astra Bertone Coupe. 1.8 03 year.

Engine warning lights coming on as described by her (I should say, she knows the difference between a piston and a timing belt!):

"The engine management light (the one that is a spanner going through the car) is on most of the time now but initially I could cut the engine and it would go away.

Now for the last couple of weeks I get the emissions light (engine shape) coming on along with the cooling system light (Battery with star in top right hand corner) although most of the time I now have the emissions light on.

The car runs smooth enough, no jumping around but when the cooling system light comes on the fan sounds like its going very fast."

Any ideas?

Buy a fault code reader?

I think (though not often) the light you have descibed is actually something to do with the alarm/imobilizer not engine management.

I'm old school. A fault code reader. Any recommendations? I always imagined such things would be expensive.

Thanks for the info. I should say, I am quoting my friend from an email. I haven't seen the car myself.

And then it still won't talk to the coolant control module, which is what the symptoms sound like.
