Update: OK, so I changed out both vvt solenoids and the cam sensors on both sides. Still getting a long start and codes p0011 and p0014. What could this issue be.

 

I think you might have the same issue as me. I literally just got my Z diagnosed by there team today I’ve been getting a p0024 code first it was p0012 I believe but they ran test for about a couple hours on my car they told me that I needed to replace the Cam Sprocket Covers which is expensive af $2700+ was the quote. I had them give me oem part numbers and I’ll look on either ebay Z1 and buy them for half the price and have a mechanic I know install them for less hope this helps I paid 150$ for this information and wasted 2 hours of my life in a waiting room.
