Fuel problem
The problems started for this Peugeot owner when his 2007 407 2.0 HDI ran out of fuel. He had just got to work and managed to coast down a hill into a parking space. Remembering that they kept a can of diesel for an old generator that was no longer in use, he had a quick look in what was the former generator room. Sure enough, a 2.0-litre metal container was sitting in the corner and had fuel in it. He poured this into the tank of his 407 and managed to start the motor, intending to fill up on his way home. He had travelled less than a mile when the motor juddered to a halt.
After hearing the chain of events, our first check was the fuel filter. Taking off the top, the contents inside appeared more like pond water than fuel. The filter had failed to cope with the muck in the fuel and a good flush of the system was needed. Even after this, fitting a new filter and filling the tank with fresh diesel was not enough, because damage had been done to the pump and the injectors were clogged.
