Vauxhall Owners Club Posted February 15, 2021 Share Posted February 15, 2021 If is occurs at a specific temperature then I would advise changing the Coolant Temperature Sensor as this would cause similar issues at a specific temperature. Not too expensive to replace and should be an easy enough job to do Quote Link to comment Share on other sites More sharing options...
