vauxhall aatra 1.6 2004 5dr hatch?

Just me again. Is your car less than 3 years old? If so it'll still be under manufactures warrantee & Vauxhall should fix it for free. Do you have any other warrantee on car? Think Vauxhall charge around £90 or so for a diagnostic test.

You'll either have to take it in for an diagnostic test. You could buy yourself a obd 2 code reader off fleadabay for less £25. Plug it in to the obd port (near handbrake lever) & it will give you the fault code. When you have the fault code, you'll then know how to rectify prob, with a code reader you can also clear ecu fault codes.
