You can smell fuel inside the cabin of the vehicle very strong. On the vin plate on my door it says in my vehicle is built on April 2011 which would qualify it for the recall from Mercedes.

I felt it was too often the message would come up. I would too off coolant each time to address it without seeing any leaks ever under the car. then 2018 thru 2019 the message would appear about 3 or 4.times per year. had it checked by Mercedes service and they advised nothing was leaking from the car and found no codes https://plaincars.com/make/mercedes-benz-cls63 https://plaincars.com/make/mercedes-benz-cls63#complaint-1960150 Mon, 22 Jan 2024 00:00:00 GMT the car started showing a low coolant message around 2017 about twice a year.
