Mercedes-Benz have identified a defect that will add another one thousand three hundred and thirty five 2015 Sprinter 2500 and Sprinter 3500, 4 cylinder diesel engine vehicles to recall 14V-764.

Oil leakage in the presence of an ignition source could also increase the risk of a potential fire.

Mercedes will be notify owners to return to their dealers to have the chain tensioner gasket replaced free of charge. Owners wanting more information about the problem are asked to contact Mercedes customer service at 1-877-762-8267. The new NHTSA Campaign Number is 15V-261
