Oh dear, there’ll be a whole new wave of people googling about manifolds to get stressed about now!

Yes. Apparently mine was in the ‘affected VIN range’! Ignorance was bliss

Wiring looms within the engine and no breakpoint to stop oil tracking up the loom until it reaches sensitive electronics - sounds just like the problems with the injector loom on the old TD5 engine (although if you were lucky that didn't write-off the engine ECU).

L405 reminds me in some respects of the P38 'Metrocab' I owned. Electronically and in theory very clever, however in practice not entirely satisfactory and laden with issues. The only saving grace of my current L405 over my previous TD6 L322 is the sheer grunt and power of the twin turbo V8. I owned my previous TD6 from new and had absolutely no problems whatsoever in 14 years of ownership. In my opinion and in order of satisfaction worst to best is P38, 2 & 4 door door V8, L405 V8, 3.5 EFi, 3.9 EFI, L322 TD6. I've also owned Porsche motors continuously over the last 40 + years and you just don't get these questions to answer. None the less, JLR seem to have a niche market. It just needs to get things right.

Indeed, which is how I was able to get the revised part. But I’ve yet to find a report of anyone else experiencing exactly the same on here.

I just hope we don’t now get the usual rush of “the worried well” now
