I have a '95 Astra 1.8 Sport. Over the course of the last year the DIC has been showing the "Oil Low" warning and has now moved on to "Oil Lack". Having checked and re-checked a long time ago and found that the level is fine I spoke to the dealer I used when back in the UK. It seems this is activated by a semi mechanical sensor in the sump. Alas, its no longer available in the UK and costs "an arm and a leg" here in France!
So, given that it is not actually serving any useful purpose now (and is on all the time) is there a way that I can disconnect/by-pass the switch so that it will not keep coming up on the dash. It's a bit frustrating having the "check" symbol up all the time!
