my car has just started chugging and the cockpit is filling with fumes , it smellls like a chip shop on fire , is this a major issue , as the car seems to drive ok?
I dont know what you mean by a "chip shop on fire" so try to improve your description. I suggest you let the car run while inspecting the engine back & AC components. Did you have your AC on? Are your vents set on recirculate or fresh air? If not, then visit a private mechanic shop thatll look it over briefly.
