We are the unfortunate owners of a Peugeot 307 XS HDI 1.6L 5 door hatch. This vehicle has had a persistent depollution system fault since it was 3.5 years old. 18 months later and after 4 different mechanics (2 of which were Peugeot dealerships) and the outlay of $4,000 we are no closer to resolving this fault.
When this fault occurs the computer limits the power of the engine when accelerating (puts it into limp mode) and shuts the engine down intermittently - e.g. when taking off from traffic lights.
Various diagnoses and repairs have occurred over the 18 months including: numerous fuel filter changes, fuel injector change (@ $2,500), fuel tank removal and clean, regeneration of burn off canister, and our favourite (which we didn't do) was the replacement of the "faulty" fuel pressure sensor in the fuel pump.
Has anyone else had this problem and had it successfully resolved? If so how?
