United Kingdom 2016 Range Rover Autobiography SDV8 Santorini Black

Very rare for the crank to let go on the 4.4. So rare that none on here have had that failure or have heard of one. The 3.0 tdv6 in the 405s and d4’s etc can on rare occasion have the crank fail, but really it’s not that common.

The 4.4 has few major issues, some niggly issues and seal failures but as for catastrophic failure these are few and far between. There is nothing that can't be fixed with a hammer😜😜

Australia 2008 Range Rover Vogue TDV8 Atacama Sand

The 4.4 with the ZF 8 speed definitely sounds like a better vehicle compared to the 3.6 with the ZF 6 speed.

But to put things in perspective, I would equate the L322 3.6 with the Toyota 200 series tdv8 Sarara or VX spec. That’s how good it is. And the L322 & L405 tdv8 just blows it away.

Maybe if the 3.6 was detuned like the 200 series motor it would last longer. ______________________________

Sorry to resurrect an old thread.

Is primary turbo failure on the 3.6tdv8 down to get failure? Therefore if you replace egr at purchase and turbo hoses then chances are the turbos will last?

I don’t think anyone has come up with a definitive “this is what causes it”. There was a chap on here that blanked his egrs and the engine suffered catastrophic failure 12 mins later.... who knows....

All I know is, I skipped the 3.6 and went to 4.4 as I didn’t need the worry.....

Sorry, I didn’t think there would be that many posts when I searched...... food for thought....

Of course there are thousands of owners who have never had an issue....

I’d not really compare the an L322 to a 200 Series, the L322 is a nicer car to drive and has a nicer interior but the 200 will still be running long after the L322 has self destructed mechanically.
There’s a good reason an L322 and a 200 of similar age are miles apart value wise.
For U.K. use though and being able to reach a mechanic easily ie not in the middle of the Sahara or outback I think the L322 is a better choice and much better value.

A Trap 

Turbos are very simple and reliable devices, they need very little to end their days when the vehicle is scrapped after 300k miles of use. Turbo failure in 99% of cases is owner related, negligence through lack of servicing and poor driving habits being the main causes.

Don’t tune the car, this over speeds the tubo and generates lots more heat to bake the journal bearing and oil passageways.
Change the oil regularly at no more than 6k miles (not the manufacturers recommended interval which is set a (or over) the max for cost saving on servicing for lease companies only)
Use the correct high grade fully synthetic oil.
Oil (not water as the water heats up quicker) fully up to temp, not via idling as diesels run cold. Just drive gently for 15+ minutes
Don’t drop anything down them, screws, washers and nuts are not good for them,- the person that had a turbo fail minutes after doing a egr blank knows about this l believe 👍
Replace intercooler/boost hoses as a routine item, a leak or split will over speed the turbos.

Finally all turbo cars have similar failure rates, diesels slightly higher because they are very small to keep lag down so work hard with high EGT’s plus Diesel engines are very hard on oil putting a lot soot/exhaust chemicals into the oil and very slow warm up times. I don’t agree you can say manufacturers X is more reliable- turbos come from a small number of manufacturers.
