My old man has the 3.6 and I have the 4.4 (all be it in an L405) my fuel economy is better than his and I have more power. I believe the 3.6 can be prone to turbo problems.

A friend who works in a dealership steered me away from the 3.0, apparently he replaces one every week but never does a 4.4

I was recently in the same position as you.
When I was researching the same subject last month, it became clear to me that the SDV8 L405 was the way to go for me.
It was always nagging in the back of my mind, if I bought a V6 engine failure could happen to me and I would always worry about that.

Round trips through Eastern Europe also weighed on my mind, being stranded a long way from home would be no fun even with LR Assist/ LR warranty etc I realise other un fortunate failures may put me in the same position, but felt this is one I could at least control.

Good luck in your search, look Nationwide get a favourite list and play all the dealers, now is a good time to buy. 2018 SE SDV8 4.4 Byron Blue

Thanks for that insight! I am currently also eyeing the L405s and especially the 3 liter diesel. I´m wondering if the crank issue on the 3 liter diesel is something that can be avoided with a preventative fix in the garage?
To my surprise the second hand L405s with the TDV6 and the SDV8 are not that far apart in terms of price. So maybe if I want to avoid an expensive engine repair in the future I should set my sight on an L405 SDV8 perhaps?

Cheers,
Johannes

the most trouble free versions

According to those nice guys at Gap who make the IID tool the 5.0 Supercharged 2010-12 is the most trouble free version of the L322 ever made....

You do need to like going to the petrol station though...  Pete

I genuinely wouldn't mind the 5L. In a post covid world, we won't do as many miles so, a gas guzzler doesn't matter too much.

I just hate going to a petrol station. If they fitted a larger petrol tank so, you're not filling up every 300 miles, I totally would.

It's well worth it, if your not driving as much then it won't be so often....  Pete

My fill up was £119 the other day in my 5.0SC. Just let it go down and pop 89 litres a time in it. With dual tanks and dodgy fuel cages you got to live a bit a gamble whether you have enough fuel or not.

But it’s cleaner and better for the environment than any of those diesels. Besides no matter how good the 3.0L diesel may be, I could deal with an underpowered fatty. My definition of adequate begins with the 5.0SC. It’s not slow but also don’t feels fast. It’s adequate.

I was tempted by a 5.0 but head/wallet won over heart.... but the soundtrack oh the soundtrack

Your "mechanic" wouldn't happen to have a 3.6 TDV8 for sale that he wants to get rid of would he?

As others have said only the 3.0 TDV6 Crank has had issues, not all but some.

Here's my experience of a 3.6:

2x leaking rocker cover gaskets - 8 hour garage job $$$
Vacuum pump - $$$
Driveway clean to get the oil off $$$
2x EGRs $$
Thermostat housing $$$
Intercooler hoses $
Many gallons of coolant $$

Seized parking brake and failed head gasket(s) - got rid! 2015 Range Rover Autobiography 4.4 SDV8

then I was lucky, I only changed the intercooler pipes and a camshaft sensor as a prevention, for the rest only frequent servicing and good oil

the L405 3.0L also doesn't have the dynamic (self-levelling) suspension which makes the 4.4 better round the corners.

4.4 all the way.

BTW get the oil cooler done as early as poss. It's a known weak spot and once done, no more worries. Also look for the 2nd turbo oil drain mod on the 4.4L.
