Due to an irregularity stemming from the molding process of the fuel filter flange, the fuel filter flange may crack when operated in high temperatures.
Consequence
If the fuel filter flange cracks, it will leak fuel which may lead to a fire if an external ignition source is present.
Remedy
Mercedes-Benz will notify owners, and dealers will replace the fuel filter, free of charge. The recall campaign is expected to begin in February 2013. Owners may contact Mercedes-Benz at 1-800-367-6372.
Notes
Owners may also contact the National Highway Traffic Safety Administration's Vehicle Safety Hotline at 1-888-327-4236 (TTY: 1-800-424-9153), or go to www.safercar.gov.
Fuel filter may leak diesel onto the road
Reported January 26, 2012Model years 2009–2011DVSA recall R/2011/172156,086 vehicles affected

Official DVSA recall text
Component
FUEL MAY LEAK
Defect
Fuel leaks in the plug area of the drain opening may occur at the fuel filter with integrated fuel heaters. Fuel can escape and is noticeable to the customer due to a corresponding diesel odour. The diesel can reach the road and as a result friction between the tyres and road surface may be decreased.
Remedy
Check filter and replace as necessary.
Fuel filter housing may leak
Reported January 7, 2011DVSA recall R/2010/20514,860 vehicles affected
Fuel may leak from the filter housing onto the road, making it slippery. The housing will be replaced if it is leaking.
