Puma 2.4 Turbo - momentary cuts out

The manifold pressure never got over 34.5 and was mostly below that.

P0089...

replace the FVV / FVC / SCV (suction control valve, each manufacturer has their own name for it)
its a common fault on a 2.4, plenty of info on AULRO

I try to buy a DENSO box DENSO one, but it can still be a Nissan, Ford, Mitsubishi etc etc other brands.

land rover - LR009837
Denso - SM294009-02514M

Thank you, have booked into the local to see if they can replace when getting a wheel alignment tomorrow. Will update.

VCV/SCV replaced and no more missing under foot flat acceleration :)

I haven't followed this procedure that Pete Bell outlines but will do it tonight as might just help further tweak the running:

Defender 2.4TDCi VCV FUEL VAPOUR VALVE - Bell Auto Services, BAS Remaps, Land Rover, Ineos Grenadier and 4x4 Specialist In York , Service, Repairs, Parts, Custom Remaps York, Performance upgrades, BAS Landrover tuning, Ineos Grenadier.

Got a Nakatanenga RAI to fit tonight which will improve air in.

Couldn’t do the relearns, the BAS tool is asking to confirm ambient temp is over 15 deg… it’s about freezing tonight.

Pete came back to me - his customer service is 2nd to none - and said leave the relearn until temps are well above 15deg as will do more harm than good if it’s running fine now.

*other systems are poor starting, some clacky engine running.

*crankshaft position sensor is my guess, common fault on a 2.4 and rarely if ever brings up a fault code.

Interesting... my local LR mechanic has seen a couple of Turbo failures whereby the Turbo lets oil past and it gets trapped in the IC and builds up to the point where the engine then runs away on Engine Oil & destroys the engine.

I'm in a situation where my 2.4 is using starting to use Engine oil (about 1ltr/4000kms) and from what I can see there is no Blue smoke coming out the exhaust. When I take the engine oil filler cap off while engine it running I notice that the cap will not sit there but the local LR mechanic did mention that these engines do breath heavily and don't read too much into it. He also said that these 2.4's don't usually burn oil either.

I've checked my Air Intake for dust ingress and it's all good...

anyone with ideas/experiences as to what it might be as to why I've started to use engine oil (engine has 231,000kms on it)?
