Never seen this in over 4 years of ownership. Just came on about 5 miles after leaving home. Stopped at a mates 2 miles later. Started up again after 30 mins and no light came on. Ran around town a bit all ok. Came on again after a few miles on the way home, again after a short stop it was clear.
Battery seems fine and everything else is working without any warning lights on. Mostly use the car for longish motorway journeys and it's never missed a beat.
Any clues what to look for before I book it in?

My first guess is IAP/MAF correlation. Somewhere between the MAF and inlet manifolds is a leak. Loose hose clip, split pipe, split manifold, etc.
Next guess would be a secondary turbo solenoid sticking. 2011 RRS HSE Luxury 3.0 TDV6 Fuji White on Ebony/Ivory

Sounds like a split inlet manifold. Does it do it when you accelerate and get the revs up? Turning off and on again resets it until the next time the split opens. 2012 SDV6 - it's missing a couple of cylinders

Thanks for the replies. Other than code reading, is there a physical check I can do? Are the inlet manifolds easy to inspect without removal. I'm handy enough mechanically, but not on engines this complex. Can a leak be heard? RRS HSE Dynamic SDV6 2014

When my manifold split, the indie that I use said they do a quick check by doing a torque converter stall check - stand on the brakes and add throttle 'til it won't rev any more (about 2.5k revs). Apparently, the inlet manifold split can be heard to whistle quite noticeably. Obviously, you need a trusted helper to do this more easily. 2012 SDV6 - it's missing a couple of cylinders

Smoke test done.
Both mainfolds split, the drivers side badly, the passenger side not so much.
Funnily enough I noticed a significant increase in fuel consumption on my last long trip, which I make regularly and the indy confirmed that a split manifold would have this effect although it was unusual to have both go at the same time.

So next question, do I go for an original LR part or is there an alternative OEM that could be recommended?

Found this on the sister site, not sure if it's useful. https://www.disco3.co.uk/forum/30-sdtdv6-i...05583.html 2012 SDV6 - it's missing a couple of cylinders

Job done. One was cracked and the other was split on the seam. I think these were the original parts as the fomoco logo was visible. Hopefully that's it for a while.
Rather poor engineering design I think to have such a critical part fail in this way. RRS HSE Dynamic SDV6 2014

The covers were carried over from the TDV6 single turbo engine that ran less boost, where they were adequate, LR realised mid 2015 they were too weak for the SDV6 and hence redesigned them. You should be OK from now on.

Quick run up the M6 yesterday to West Lancs. 170 mile round trip. May be imagining it but the engine has never felt better. RRS HSE Dynamic SDV6 2014

My assumption is with multiple part numbers, there must be a revision with each successive number, and the previous ones are unacceptable by Ford / Citroen / Land Rover.
