2016 W205 C300h low mileage, circa 4,500 miles with swirl flap error. Three times now, each time in December. First time Dec 2018, then Dec 2019, and then last week Dec 2020.
First two times checked and error code cleared by Mercedes Mobilo - claimed that the Swirl Flaps were operating normally under test using Xentry. Mentioned this to the dealership during service but was told to bring the car to them without the error being cleared by Mercedes Mobilo. So this year I got the car in with the annual service/MOT. Dealership cleared the error to get it through MOT. But when I collected the car it was back on.
The dealer tried clearing the code again but now will not clear. Keeping car until after the holidays for further diagnostic. They think it could be due to carbon issue due to the low mileage - unsure if this will be covered by the Mercedes extended warranty!
