Long burning of the "spiral" icon of diesel cars is most often observed during the cold time of year before the engine starts and means warm-up heat. But it happens that this icon lights up during the movement, and the car loses power and is poorly dispersed.
The reason most often is insufficient or overpressure from the turbine. One of the possible culprits is the exhaust gas recirculation valve (EGR), which can be weddled for various reasons. The other is the pressure regulator. In either case, the owner should contact the diagnostic service to identify and resolve the cause.
