I've just serviced my Logan for the first time since buying it second hand, on the 48,000 miles service. I was sold a fuel filter by the motor factors, but I can't find one on the car. It's the 1.5 diesel essential blue. Does anyone know where I can find it, or know if it has a lifelong filter fitted please? My daughters boyfriend(a fitter), couldn't find it either. Unfortunately, the car came without an owners manual.
