My Vauxhall Astra 1.7 TDI is suffering from a lack of power at low revs without smoking from the Exhaust.
Using the demonstration here [url=http://www.youtube.com/watch?v=bK-Y24UVTJ8]here[/url] and cross reverencing [url=http://www.vauxhallownersnetwork.co.uk/showthread.php?t=164990]here[/url] I retrieved the error code 0100 which confirms my suspicion regarding the Mass Air Flow Sensor.
(Quick: to view error codes, press the brake and accelerator whilst turning the key to position 2, 10 flashes = 0)
How to see error codes on a Vauxhall astra without a diagnostic tool
Learn how easy it is to do diagnostics on a Vauxhall Astra 2001 This should work on cars from 98 onwards, I'm no mechanic, it all down to research and asking questions. Plus I'm cheap and tried to save money lol...
How To Clean a Mass Air Flow Sensor (MAF)
Here I demonstrate the simple steps involved with cleaning your mass airflow sensor. In this particular case I was troubleshooting a rough idle on a 2006 Chevy Colorado 3.5, but these steps can work for almost any vehicle. If you have any questions feel free to post them and I will do my best to help!

P0401 EGR Valve Port Cleaning
This is my DIY for clearing the CEL code P0401 (EGR Insufficient Flow) on a 98 Honda Prelude.
In cars with OBD2 if the EGR valve is restricted by carbon deposits it will detect that and throw a CEL. To get rid of that CEL you must clean out the carbon to allow flow.
After combustion occurs within the engine it creates Exhaust. Gas from the Exhaust straight from the engine is very bad for the air. The EGR valve recaptures that Exhaust and runs it through the combustion process again, which lowers the temperature of the fumes (Exhaust gas) and lowers the amount of pollution exiting into the atmosphere.
If you don't fix it you won't pass SMOG in California. You may experience rough idling and poor acceleration.
Tips:
Get your "EGR port plugs" from Honda. They will have it.
Removing the injectors are important to allow clearance to the port plugs.
When you pull out the injectors you might as well clean them since they are out.
Slide hammers make pulling the port plugs out easily.
Drill with a bit the size of your tap. Drilling halfway through the port plug to should be enough distance to fully grab the port with the slide hammer.
If after you clean your ports and valve the CEL has not been cleared, you EGR valve maybe faulty and needs to be replaced.
