Hi. How's that? If you dont start the engine how it gets warmed up? do you have a programmable FBH? If you meant you start it but dont drive it 5 minutes untill it's warmed up don't waste your fuel for nothing cos if it's sluggish due to the autobox that one won't warm up at idle, nor the engine too much, hence LR's recommendations mentioned in the WSM which must be both respected:I don't start engine until warmed up! Have about 5 mins before pulling away!
If the wastegaate modulator fails it goes to overboostCould also be the wastegate modulator if there's no boost......
