| Description of the problem | After extensive reviews of tdi forums, common rail forums, diesel forums i have found a commonality in the failures in the high pressure fuel pump (hpfp). Mainly those failures were attributed to metal shavings/particles/rust found in diesel fuel systems. The fuel level sending units are usually rusted in each case and most likely is the source of metal/rust contamination and ultimately cause of the hpfp failure. Failure of the hpfp causes the cr to lose pressure therefore the injectors are starved of fuel or worse clogged with rusted metal particles. This sudden loss of fuel causes the engine to shut down instantly along with power steering and power brakes. Depending on the reserve vacuum volume in the booster, consumers may or may not have enough vacuum to adequately bring the vehicle to a safe stop. Also the steering wheel would feel very heavy and the consumer may or may not be able to steer clear of an accident. I wrote to mbusa noting this cause and urged them to investigate this matter seriously before any injury or death happens, also to institute a voluntary safety recall of all cr diesels to determine if rust from the fuel level sending unit is present. I proposed a remedy to mbusa to change out the rusted units for stainless steel ones. I also requested that mbusa provide unlimited warranty replacement free of charge to all bluetec owners and reimburse all those prior to the recall, including any rental car use. |
