What should I do?
I'm driving on the highway at 100-110km for an hour, glow plug light comes on, tried to accelerate but vehicle would not speed up, I could hold speed at 90km range but just barely, this lasted about 30 minutes. Made a stop, shut down for 30 minutes and all ok after that, happened 30 days ago.
Ran a scan yesterday and got PO401 & 403.
Vehicle still under dieselgate warranty for another 10,000 km. Problem has not happened since?
I can post full scan but for now here are fault codes;
