I have very recently bought a 2.0 Diesel Cee'd Sport CRDI 2008. As I have never had a diesel before I have been advised that I should useRedex diesel fuel system additive. However someone else has told me that this should not be used if the car has aDiesel Particulate Filter. Please can anyone advise how I work out in my car has a DPF and whether I should use the additive. Thanks.
