Hello, I turn to you, because my buddy with his Kia Carens IV 1.7 CRDI 136 PS BJ 2016 approx. 250 TKm does not get any further with his troubleshooting. The car takes a long time until it starts and then it trembles at the beginning and after giving gas it behaves almost normal. He has already renewed several things as well as: dual-mass swing wheel new, clutch new, throttle valve new, all injectors overhauled, diesel filter new, exhaust gastemeperatursensor new, diesel particle filter professionally acidified Is one of you familiar with these problems or does someone in NRW know who knows Kia very well? Would be nice if my buddy can be helped here. LG DBSveny40
