I’ve driven an Audi A6 S-Line 2.0TDi for 4 years now and I’d like to make a reduction now. My attention has fallen on the Citroen C4. Beautiful look, depending on the model super interior and at 2-3 years old an ingenious price-performance ratio. My concerns are now the following: Since I have had very bad experiences with my 2.0TDi, regarding longevity and childhood diseases (cylinder head crack at approx. 90,000, exhaust gas return valve etc…) and i ch is completely new at Citroen (until now only AUDI) now the question: What do I have to pay special attention to with a C4 saloon 1.6HDi/2.0HDi. Is the 1.6HDi sufficient with its 109hp or should it be the 2.0HDi? How does it look with car tax differences, consumption, running culture and response behavior? Are there “children’s diseases” I should pay special attention to with the C4? How is the Citroen-Navi? So what, let’s explain the world of Citroen 🙂 Thank you already !!
