All standard, I did have the light come on a couple of years ago which was fixed with a replacement temperature sensor by Vauxhall.
On a separate note, one thing that is apparent, if in traffic and moving along in first with no throttle the car pulls itself along fine, if I touch the throttle just a tad then I get the kangeroo effect, it does jump around a bit until a bit more throttle is applied, this has been happening since I bought the car several years ago, note sure if the characteristics of the car or a problem somewhere.
