My check engine light is on and the code spits out P0304 with info “pressure line fault: solenoid 4 short circuit to ground”

Apparently it’s the 4th cylinder but I’m not sure what exactly the info stands for..

What is solenoid 4 and which pressure line?

 

Car is 2004 xj8 not the supercharged trim

 

Same as any of the codes P0301 to P0308 - have a read using Search. Many many answers all ready for you.

 

To search the X350 Forum, go to the Forum opening page and type P0304 into 'Search'.

Sometimes it can be better to type 2004 Jaguar XJ8 DTC P0304 into Google?

Here is what JagV8's suggestion of a search of this forum delivers for you:

P0304 is a cylinder 4 misfire. Not sure where the description of "pressure line fault" is coming from.
