Strange errors occurring randomly 2012 LR4 HSE
Nice find! Glad you got it! Those grounding issues are ALWAYS a pain to track down! -
Strange errors occurring randomly 2012 LR4 HSE
Everything you’re describing sounds like there’s a CANBUS issue…which is usually caused by some sort of corrosion. Typically it’s a corroded ground, but every now and then, it can be a bad module. The usual suspects are the ground points behind the passenger and driver’s footwell kick... -
Strange errors occurring randomly 2012 LR4 HSE
I saw your other post directing me here, just wanted you to know! This has got grounding issue written all over it. If the car stays running and just the displays shut down, then as far as I can tell, your BCM is most likely fine. If it goes out, the car is gonna quit as EVERYTHING talks... -
5.0 supercharged into an LR4?
Actually, it’s significantly easier than the NA to SC swap. Let me caveat this with, i haven't done it myself, but the systems and software interface in the SDD tool is all the same Swapping a V8SC into a V6SC’s place is ALMOST plug and play. The intercooler pumps and plumbing are all the... -
Struggles to start and single bank misfires only when cold?
I went ahead and pulled the live data for the throttle body. This is before start with the engine on Here’s the data for “high idle” just after start: And finally, here’s the info for idle: It sorta seems to me that the throttle is open more than it’s supposed to be? This causing the... -
Struggles to start and single bank misfires only when cold?
Ok folks, I've been trying to locate this particular gremlin, and I'm hoping someone else has experienced it. It started shortly before I swapped my chains out roughly 25K miles ago...or about 3 years ago. (Yes, I've been trying to sort this for a while) Here are the symptoms: When it's cold... -
Misfires on one side 3L SCV6 2015
On mine, I was getting misfire codes every time I started up. Along with “too rich” on both banks. I started with the O2 sensors as I thought I had good MAF’s. Even though there were no O2 sensor codes, almost all my misfire codes went away. Then, I swapped the MAF’s out and all was good to... -
Entire bank 2 misfire
So, I’m jumping in here as I’ve been trying to diagnose something similar in my 2010 LR4. So, this started about 3 years ago. I thought I’d get it when I did the chains. FYI, when I did the chains, I replaced the injectors, plugs, coils, can variators, water pump, front and rear cross overs... -
Finally finished, Bosch for Denso Infotainment Swap
I totally agree! That's the tact I'm taking with my 2012. The engine....which I almost had running and had to break it down again....then suspension....Brakes are sitting in the garage waiting to go on, but need be able to afford the new 22" tires for it first....then the rest....So much to do... -
Finally finished, Bosch for Denso Infotainment Swap
Ok, one final post and this one is important if you're thinking of doing any sort of OE system upgrades. So, while my system has been up and running for a year or so now, my son has had the car at school, and I only got it back this summer. One of the final "glitches" I've been trying to... -
Finally finished, Bosch for Denso Infotainment Swap
Honestly, now a days, there are a lot of aftermarket units that will function with our systems. There are so many different ones, I don't know that I could recommend one over the other as I have never personally tested them. I know a lot of guys like the simple bluetooth dongle that allows... -

Hey All! It's been a hot minute, and I've been making progress, it's just been slow. Hand sanding the block is taking forever, especially since I can only get to NJ roughly every other weekend. That said, the left bank was way out of whack all over, and I'm just now getting it back into... -
Exhaust solutions?
My plan for my "milder" LR4, is to install 2 aero turbine 2.5" mufflers in place of the stock muffler and resonator. Then install two 2.5" aero turbine resonators just before the end of the exhaust pipe. That'll open it up, and should sound A LOT better, but not have too much drone. -
Bad ECM or something else?
They will get hot, but typically they’re only gonna get hot when you’re really Pushing the engine hard and it’s hot out. Sitting at idle, there’s no requirement for charge air cooling as the SC really isn’t working, and hence the pump will not turn on. If the pump’s not on, it won’t push... -
Bad ECM or something else?
A couple thoughts… I think you’re looking in the wrong place. If the whole OBD2 system is down, I would be checking the connector ground behind the footwell kick panel. (Both sides just to be safe). The PCM being down won’t cause full loss of communication, heck I’ve only had 1/2 my modules... -
Project Dark Knight Rising
Yes, I've been looking at that. It still has the same charge cooler design though. I mean, that's the great thing about it, it's 100% stock bolt up! With heat soak being such an achilles heel for these things, I feel like even the Harrop SC will suffer the same issue until the heat issues... -

No, I’m looking at something to increase airflow and reduce temperatures…and allow me to possibly swap out for a larger SC. I’m thinking of trying to mold something like the whipple design: Or maybe the coyote: I feel like a taller SC cover plate will help the airflow better withing the... -
2015 LR4 - Major engine work - Sell / Sell Parts
Honestly, for the cost, I'd try and sell yours as a fixer and just get another used one. In the end you're going to come out WAY ahead. That said, these things tend to sit for a while as fixers. However, a low mileage 2016 will probably only run you $15-$16K. So, you'll already be $3K ahead... -
2015 LR4 - Major engine work - Sell / Sell Parts
Ok, lemme first say I'm looking at your pictures, and the damage....if any, isn't all that bad. I've seen these engines run just fine with bent valves and imprints in the pistons. I will say $19K for a reman engine sounds about right given the fact that $12K is probably the engine cost... -

No, unfortunately I didn't take any "pre-sanding" measurements save just putting my straightedge against the block and looking for light. That said, I didn't see a whole lotta light. Granted the angle was terrible, and it's hard to see through the front of the grill to check. Which leads... -

OK, so I finally got a little work done this past weekend. It took me roughly a day or so to get my deck prepping tool made...and that was mostly because it took the JB weld that long to set up. Basically, as I don't have the tools on me to pull the block back out, I'm "decking" it in the... -

Thanks! I appreciate the support! I've got the heads back off and am taking them to the machine shop sometime this week to be pressure checked, cleaned and resurfaced. (Not gonna lie, kinda jacked up the one head trying to get it pried off the block. That said, I've heard a rumor that the... -
Project Dark Knight Rising
I plan on pulling the heads, again, to get them re-checked at a shop near me. Maybe they got damaged during the move to TN or something? As for the block, that's a little trickier. I don't have the capacity to lift the body to pull the block again, and there's a lot of crap that has to be... -

Well folks....it's been a rough weekend. Turns out, I didn't screw up and nothing broke, and the timing is dead on. Then I went and checked the cylinders again and noticed a lot of oil pooled up around the head gasket, and potentially some coolant in one cylinder. (Although there's a chance... -
2012 LR4 infotainment problem. Help please!
I’m not sure whether it replaces the satellite module, but I know we don’t have them here in the US. It’ll look a little different, but that’s where the module is located. You’re welcome btw! That said, it was the. It’s from PowerfulUK who made the video. Although admittedly, I’ve watched...
