    Code U0001 & U0101

    Could have even been a loose connection at the battery...even that would create havoc

    I did a thing

    So I pulled the trigger on this...will let you all know how it goes. Just rolled 140k but I’m keeping her for a while. Photos are not my truck. It just shipped.

    Code U0001 & U0101

    sounds electrical to me. All fly by wire so slight variations in voltage cause all sorts of issue. I’d start with battery check then move to alternator. Check what voltage your truck is charging at...if it’s around 12 or below, you’ve probably got a bad alternator. Mine was charging at 11.7 and...

    Second Throttle Body Replacement

    have you cleaned your tb recently? If not, it’s an easy fix. Even the smallest amount of dirt can cause issue. You’ll get a throttle position sensor voltage out of range code (if I recall correctly). After cleaning, a recalibration/reset with gap tool is also recommended. I had an issue where...

    Transmission issues

    Definitely read the codes. As was stated, low voltage is the Occam’s razor. I’d next try checking your fluid level (truck running, on level ground, still cold). The fluid should be a steady stream, clean looking and not burnt. if you’re low on fluid these transmissions are very picky with...

    3K oil change intervals for our LR4s?

    mobile is Alabama, but...you are otherwise 100% correct- no oil change should ever go 15k no matter what oil is involved...especially with a known timing guide weakness.

    Purchasing Pre-Owned LR4: 2015 vs. 2016

    I’ll chime in on shipping. It’s very easy to find a national carrier that is bonded and insured. I have direct contact to one who is fantastic and I have used twice (I’m super cheap, so I hunt for a deal until I find it). If you’d like her information, she was great to work with and negotiated...

    Adding Rear Diff Motor

    and a whole lot more...all the wiring the control module, etc. I think someone did a write up on here of a conversion using a diff off of a parts truck. Not a plug and play.

    Vacuum Leak in 2010 LR4 V8

    As far as I know, if a cel comes back on it indicates a new code has been stored, not that an old code has to be “run through a drive cycle”. Did your mechanic tell you that the light came back because it needed to go through a drive cycle? the only reason for a drive cycle is to check all...

    Vacuum Leak in 2010 LR4 V8

    hmmm. I’d be skeptical of a mechanic that tells you this. CEL should and can be reset and codes should not reappear during initial drive cycle. Vacuum should be immediately restored and CEL should stay off. It is true, if the computer is not reset, the CEL will turn off after it senses the...

    Vacuum Leak in 2010 LR4 V8

    did you check your pcv valves (on top of the passenger side valve cover). They are rubber valves and tend to develop a leak after about 100k mi. Spray some brake cleaner there and see if the engine stutters. If so, that’s your leak. Replacement is cheap, just make sure that you don’t break the...

    LR4 Transmission Heat Shield is missing. Is it necessary?

    not sure the lr4 had a heat shield on manufacture. If it did, mines missing too as are most others. Every one I’ve seen from below doesn’t have one.

    IID Tool - RPM fluctuates, hard downshift?

    that’s fantastic news!!! I did all I could think of and had a transmission shop who works on zf trans take a look and still ended up with replacement. I didn’t have any abs faults though...which would make a definite difference. I’m guessing the abs faults caused the transmission lockup to...

    IID Tool - RPM fluctuates, hard downshift?

    depends if there’s any damage to your transmission. I tried a fluid and filter change first and added some dr tranny which helped for a while. You might get away with another 6 mos to a year out of the TC. I put a new to me transmission (had 40k miles on it and came with a torque converter). The...

    IID Tool - RPM fluctuates, hard downshift?

    torque converter on the way out. Just had this last year.

    P2187, P2189 2015 LR4 HSE

    possibly a vacuum leak. Check pcv valves.

    Low temperature affecting oil level sensor?

    gap iid will give you a live value of calculated volume in liters. It will also give you a measurement that I’m assuming comes from a sensor. See attached. This is from a demo screen (not my actual truck). Point being, your volumes shouldn’t vary that much in cold weather, but wondering what...

    Disco 4 steering issues - this one is strange

    could be a coolant leak causing belt to slip. I’d check water pump for failure

    2011 LR4 Misfire/rough idle

    Not super familiar with high pressure fuel pump but sounds like you may have a short, a loose connection, corrosion, or faulty pump, etc... it sounds to be fuel delivery related by those codes, but gap tool may be able to tell you more. You can check specific pressures and values with gap tool...

    2011 LR4 Misfire/rough idle

    running smoothly as in you can’t feel the misfires and codes pop? Or you can feel misfire until it heats up and then runs smooth? Is it throwing codes when it is hot (if you clear codes do they come right back)? running down some ideas for you. These are possible but less likely. PCV valves...

    2011 LR4 Misfire/rough idle

    Oil pressure does affect the tensioner, yes. Not exactly sure why temp would eliminate the misfire though. It could be as simple as a loose wire connection that as soon as things expand, eliminates the misfire. Did you bring it back to the mechanic who did your ignition system? Sounds like...
