This new Mercedes benz diesel recall affects vehicles powered by the 3.5L BlueTec turbo diesel V6 (shown on the right) from the 2011 model year including the E-Class models built between July 2010 and February 2011, GL-Class units built between March 2010 and March 2011, M-Class models built from January 2010 to March 2011 and R-Class vehicles built from April 2010 through April 2011 along with the new 2012 S-Class sedan. In total, 6,872 vehicles are included in this recall in the US market; although the German automaker believes that less than 1% of these vehicles will actually exhibit the problem which has caused the recall.
In these freshly recalled Mercedes Benz vehicles, the fuel system includes a heating element that helps to prevent from sluggish performance in cooler weather by heating up the diesel fuel. When diesel fuel gets cold, it thickens or “gels”, which can make the vehicle harder to start along with causing diminished performance when driving. Unfortunately for the owners of these diesel-burning 2011 and 2012 Mercedes Benz vehicles, the fuel filter may develop a leak around the heating element and as diesel fuel leaks out of the line and gets onto the heating element – there is a very clear danger of fire. Even when there is not a fire, a fuel leak can present one heck of a mess under the car and in the garage as the leak worsens along with hurting your fuel mileage.
This Mercedes Benz BlueTec diesel recall is expected to officially begin in November at which point, owners of the 6,872 units will be asked to return to their local Mercedes Benz dealership where the fuel filter and fuel heating system will be inspected. Should the fuel filter and heater assembly appear to be problematic; the dealership will replace and repair the faulty components free of charge to the customer.
