I need to know if this engine is a n52 or n51.
Here is an emission sticker from the hood

I've been comparing Carfax vs Epicvin for a long time, which VIN checker is the best. I often use them, in connection with the current work. The most convenient was Epicvin. You can try it, there are free features there

I think it would be better to try and go to the service center regarding the model of your car, so the specialists would help you to identify the problem and key issue of your question. But yeah, probably it would cost you some money... Unless you have a friend who is a mechanic and who is willing to help you, heh.

Personally, I have a friend of mine in the service center when I had trouble identifying VIN numbers. I also visited some forums regarding it but was not successful. Moreover, the problem of VIN identification was because my car was previously stolen and hijackers removed the VIN. Only my trip to Daniel ( as he was a Jaguar Mechanic ) helped me a lot to sell my Jaguar E-Pace afterward.
