Porsche Cayenne 92A facelift diesel or gasoline.

Hello dear Porsche friends Since I am currently driving a BMW F10 and I want to get an SUV soon I loved the Cayenne. Find it cool from the optics Facelift 92A, I also like the many buttons (I don’t know most of them ). Now to my question, would interest me either for the diesel with 262ps or the gasoline with 299ps. Drive actually almost only city and in the year around the 12,000 km. What about the two motorizations eu Re recommendation? Does the petrol engine still have the problem with what the Panamera had? Expect a child soon what about family fitness? Would I be happy about the answers from the Cayenne drivers
