Hi all,

My new(ish) diesel 2.2 is driving very well, especially since I got the brakes replaced. I did have a strange issue yesterday though while driving down the motorway. I was in 6th gear and got up to 90 mph when I lost power and the coil plug lights flashed on the dashboard. The only other time this happened was when I pushed the rev counter in the red but this was not the case here.
There are no codes and after a restart all seemed okay. Would there be some limiter that causes issues at 90 mph?
How do I troubleshoot this?

Thanks
Alex
