PEUGEOT announced a problem with the 407 affecting a total of 115 vehicles.
It has been identified that on certain vehicles, a fault may be present on the diesel fuel circuit return pipe at the location of the pressure sensor.In the manufacture of the pipe an excess of material resulted in a reduction of the pipe's internal diameter therefore restricting the fuel flow, and a risk of a diesel leak from the fuel connector.
The following remedial action is necessary to address this problem. Subject vehicles will have the diesel fuel delivery pressure in the injection pump checked. This will check the conformity of the pipe, which in the case of nonconformity will be replaced.
If you think that your vehicle may be affected by this recall you should
find your nearest PEUGEOT dealer
who will be able to confirm whether or not your car is safe and arrange its free repair if necessary.
