TD5 - Horrendous MPG

Isn't the TD5 a BMW-sourced engine, or is my memory failing me? I remember them as being very rattly-sounding units from when I had a Discovery TD5.
Nope. Completely unrelated to anything BMW. The Td5 is all Rover/Land Rover. It bears some resemblance to the L-Series architecture. But shares no components. The L-Series is a very good engine and still in production and use in certain parts of the world, only updated further. The Td5 should not have been ratterly at all. Arguably the nicest Diesel engine Land Rover fitted to the Defender or any traditional live axle Land Rover. Albeit not the most frugal.

I was reflecting on this when I was following a well driven Defender TD5 down some lanes on the weekend. I think that the TD5 might be the only thoroughly decent engine that BMC->BMH->Leyland->Rover->sThe Td5 should not have been ratterly at all.

tshow ever created from scratch in house. As in the only one that wasn't horrible, barely competitive, or without at least one or two really serious caveats. The A and B series came from Austin, so they can't even take credit for those. Great engine, would have been good to see it developed further and maybe into the planned 6 cylinder variants too but I understand that unit injectors would not be able to meet more stringent emissions regulations, and developing it for common rail made less sense than taking a BMW diesel engine "off the shelf" at the time.
Hadn't you heard?
In the last 10 year the OP has fixed the problem, remarried, moved house, sold the Land Rover and bought a Range Rover Sport SVR.
When the RRS wasn't broken down the MPG was poor. Despite having 576hp the 17MPG wasn't quite up to expectation. He went on the RRS forum in 2018 to ask for advice and should get a definitive answer in 2028 ;-)
