I started a thread a couple of days ago saying I had a oil pressure warning come on. Turns out that it was actually a coolant warning. To be honest it is a bit if a relief because I was worried I may have done some damage to the engine if it was ran dry. Brings me to the next question of why the alarm came on, it was only on for about 20 secs then went off again, not seen it since. Any one got any ideas why this warning came on for such a short period of time? Temp gauge is bang on 90. I was sitting on a slight hill at the time, could this have caused it?
