Hi all I'm fairly clueless when it comes to cars but I have an idea about how things work.
That being said my engine light remains on, on the dashboard and I know that without running a diagnostics on it I can't tell what's wrong. I've heard there is a method of getting the fault code yourself if this is true can some one please explain or refer me to a place where I can learn how to do this? I don't have £50 to spend on getting this done.
Thanks in Advance

We have the DSG judder on our 200 Golf 1.4 so it has to go, I'm not spending £1300 for a new clutch pack.
What Golf sized cars have been available in the past 3 years with a torque converter box?... Read more
The C4 can now be has with a 1.2 130PS Pure Tech 3-cylinder engine with an EAT6 which I believe is a six speed torque converter from the Japanese Alsin company.
Fairly sure this is an automated manual box....

Me too MrDanno. Some of the best information available with a scantool on a petrol engine is short term and long term fuel trim. With the right knowledge this can tell you a lot about the engine and the way it's running.
Sensors generally provide a return voltage to the ECM between 0.5v and 4.5v. Between 0v and 0.5v would flag an open circuit code, and between 4.5v and 5v would flag a short circuit code. These may be interpreted as voltage low or voltage high.
But as you say, a sensor may be reporting within its parameters and still be faulty. No code will be set because the ECM is happy that its return voltage is within limits. Mass Air Flow sensors are good examples of this.
