Just been looking through the technical bulletins and there was a very interesting ECU update for the carens, soul, ceed/sw and proceed 1.6 CRDI engines. It was named EURO5 DPF protection. Kia arnt beginning to see problems with DPF filters already are they? It didn't specify what level of tune the engines were, but it also had a U2 knocking improvement to the ceed also. If any one wants the TSB numbers they will have to let me know.
