2006 RR No CDL Lock
In my 2008 you won't see the lock symbol or have the function work unless the vehicle is in one of the off-road modes. If you select 4wd info in regular road mode the screen shown is all you see- John Robison

3K oil change intervals for our LR4s?
The 2010-newer V8 engines are substantially the same inside. Bearings clearances, for example, have not changed. If your engine is the same, why wouldn't the most current factory advice apply? In my opinion there is no reason to think an oil recommended for a 2016 motor would not also be...- John Robison

3K oil change intervals for our LR4s?
As I said, the 10k interval works for most people. But as a service manager I see lots of vehicles, and I have seen enough where 10k didn't work to be cautious. Sometimes it's owner error - people assumed there was wiggle room, and they actually went 12k a few times too many. Other times its...- John Robison

3K oil change intervals for our LR4s?
With all due respect, there are many opinions on this because there are a great many uninformed people out there with good intentions and limited understanding of the underlying theory. That is a problem with the auto trade in general, not just this post. Anyone can set up shop as a mechanic...- John Robison

3K oil change intervals for our LR4s?
With the correct oil and filter, The 10k intervals are OK for most people, most of the time. The problem is, most isn't all, and if you are one who isn't ok, no one is buying you a motor. There is a widely held misconception that motor oil degrades in a linear fashion. It does not. Oil can be...- John Robison

3K oil change intervals for our LR4s?
Quijote, the engine in the photo is a newer motor, and it had chain troubles. I think these problems persisted into 2015 and possibly beyond. It's hard to say because the motors are not old enough yet. We thought the Bosch motor in the MY 2000 Discovery was a huge improvement and it took a...- John Robison

2012 LR4 - Ticking saga...
We have found a lot of variation chain noise in these engines. Often when people have chain repairs done the shops take a shortcut and change only the tensioners. It is also common for shops to change the two cam chains and leave the shorter chain to the high pressure pumps, because that...- John Robison

3K oil change intervals for our LR4s?
You are right the 2010 engine has a different block from the 2009 style. It has a new number but is clearly a derivative of the first. We rebuild them steadily and from that vantage point (taking them apart) they are newer and older members of a family, not unrelated products. However that is...- John Robison

3K oil change intervals for our LR4s?
I have been a Land Rover service manager for 33 years, since they returned to North America in 87. There was never a time US market Land Rovers required 3,000 mile oil changes. In the case of a LR4, the engine is derived from a Ford design from the 1990s that used a $10 oil filter. When they...- John Robison
