The soft sand - "feshfesh" - blocked the air filter so that the car stopped.
The TV pictures showed how the crew struggled to clean the clogged air filter from the sand.
The stretch was red-flagged due to Solberg standing in the middle of the road.
Solberg has started again after many minutes of stopping.
It is still unclear if the car was damaged.
The last stage contains six distances.
SVT broadcasts from the final powerstage starting at 12.45 in SVT1 and play.
