When it happens, diagnosing the issue is a pain.

I see people posting similar comments in justification of coil relocation. I'd love to hear the diagnostic procedure that all of these diagnosticians are using that requires more access to the coil than what you already have. If I wanted to go all out with diagnosis for a suspected ignition issue on a DII, I would be using my Picoscope with an inductive pickup on the wires, which wouldn't even require direct access to the coil packs. Without secondary air injection there is plenty of room to access to coil pack connectors or swap individual wires.

Btw, I'm not calling you out specifically, I've seen several others say the same thing and I'm pretty sure most couldn't diagnose a blown fuse

ahh the picoscope. never thought I would hear that mentioned on dweb. most underused and miss understood tool out there. have used that to fix cars that engineering couldn't figure out. on a daily basis. my take on relocation is if you like and is simplifies your life... why not. just not really a fan of mods that modify wiring unless you fully understand electrical to the point of theory and repair. when ever I get a car that has had wiring mods, I either decline diagnosis or charge accordingly.

You will be shocked and amazed at what these clowns know. My advise to you is don't even start reading posts that are longer than 5 paragraphs. Those come from a special place in hell.
Daily you fix cars that engineering can't fix? Your car company clearly needs better engineers.

Maybe I just got a crap-load of bad coils; I don't know. I've been through four legitimate failures on one vehicle, and two on another. That's not the only reason, though.

Faulty plug wires: We've all had one or two at some point or another; I believe this vehicle has suffered six, but it's been a while.

Regardless, I'd love to see anyone here replace a plug wire without removing it from the coil. :ROFLMAO:

Then there's the quick and clean access perspective, and so on. There are lots of reasons. Land Rover put them in a stupid place.

Cheers,

Kennith

You better get your mom to help you strap your helmet on Kenny. I think it's about to get sporty around here again.

Why does it have to be sporty?

You guys need to chill out a bit. The funny thing is, I agree with pretty much everything said in this thread by both sides - maybe you aren't as far apart as you think.

I bought myself one and use it more than my DVOM. It's amazing how much more often you use a tool when it's in your tool box vs on a shelf in the shop.

By the way... Here is this tiny gem:
I bought its granddaddy (same size, fewer features) four years ago to troubleshoot an electric keyboard. It paid for itself immediately.
Now, I never leave town in a Land Rover without this thing in my glovebox.
It has very few controls, so it is as much a PITA to learn how to use as a Yaesu multi-band radio, but once you're familiar with basic operation, it is awesome.

I had forgotten about that. I need to get one for at home.

I find that once it's out of the box with 2 leads and an amp clamp on it I'll grab it instead of the fluke meter. But if it's all put away it's usually faster for me to grab my meter. The meter will get you almost anyplace you need to go, but you have to know when to put it down and grab a scope. I know Jymmie uses it all, even the NVH (noise, vibration, harshness) adapter deal. I've used that part of it but not as much as jymmie.

I find that I save time by just starting with the scope because if I end up taking it out I'm likely rechecking what I've already check with a meter. It's also nice for justifying endless amounts of straight time ;)

True. But if it’s communication bus( Lin, can, flex-ray) pico 100%. I still use volt meter for volt drop, resistance, circuit integrity.
