The common cause of the problem is the damage to the interculler tube. Another common cause of the failure is the violation of the work of the DDP due to the poor quality of fuel. In addition to the inspection and replacement of the interculer, it is possible to replace the fuel filter, which in the Mercedes E-Class (W211) with diesel engine is located on the engine in the fuel ramp area. If there are more complex problems with the TDP and the injectors, it is advisable to contact the diesel engine fuel repair center.
