I will shortly be doing my first at-home oil change on my '03 HCH. I have done many oil changes on my other cars throughout the years and wanted to know if their is anything special that I should know. The car did not come with a manual so I will post what I think should be the correct procedure and ask my learned collegues to make any corrections/suggestions:

1) Let the engine warm up.
2) Remove the plastic undercover - any tips on how to take off those clips without breaking them would be appreciated.
3) Take out the drain bolt and drain oil.
4) Take off filter
5) Let everything drain for half an hour
6) Clean off threads for filter and plug
7) Reinstall cleaned plug - I read elsewhere that I need a new crush washer
8) Wipe a little clean oil on the filter ring rubber and install, quarter turn more after hand tight
9) Refill crankcase - how much oil?
10) Start car and look for leaks
11) Reinstall plastic shield

Are there any electronics that have to be reset? I believe I read that a warning light comes on when maintenance is required.
Thanks!!
