so I was driving my car this evening all perfectly fine then the engine management light started flashing on the dashboard and it went into limp mode and was really down on power, I drove about a mile switched my engine off, returned 20 minutes later, start the car and the light has been off and hasn't been back on? Recently had a problem with the heater motor not working, was told I needed a new one but has since started working again, not sure if it sounds related?
