Hi there, have got a little issue with my 2016 4.4 sdv8, when i switch the engine off i can hear what i think is the glow plug relay clicking, i plugged my gap tool in and have got a p0383-11 glow plug module circuit low-general electrical faliure- short to ground and then glow plugs 1-2-5-6-7-8 have a fault circuit open-component failure-internal failure, p0671-96. it runs fine no lights but would like to get to the bottom of the problem.
thanks.
