I am not a LR V8 expert by any stretch of the imagination, so I entered "GEMS Fault Code P1316" into Google, and got this site
http://www.troublecodes.net/landrvr/ Which says that it's a Misfire Excessive Emissions Fault. So I would probably check for contamination from overfuelling of something like that maybe? As a check I looked in a couple of other sites and found this at http://www.landroversonly.com/forums/f39/after-weeks-research-p1316-codes-41140/ Code P1316 Reason: 1. Spark plugs 2.
