    Windshield and Rain Sensor

    If you still have the original windscreen, the odds are that the glue that secures the optical rain sensor to the inside surface of the glass has let go. There is a plastic clam shell that unsnaps into two halfs behind the interior rear view mirror that hides the sensor. I suggest you unsnap...

    Suspension Fault, HDC unavailable,Transmission fault, brake switch

    Yes, much appreciate the post; the brake switch circuit seems to affect the whole vehicle - guess it messes up the car computer - sends or not sends odd signals to the computer than then the 3 goes crazy. It seems to all seems to start with water. It is wonder that 3's can keep running in the UK.

    LR3 won't engage starter

    Replace the starter. I had a starter problem that took me at least six months of fooling around before I got smart and threw in a starter even though I knew it did not need one. Well to my surprise, that was the solution. I did get clicking sometimes but I thought it was something to do with...

    Transmission Fault and more

    I noted your comment re cleaning the battery posts. Given that your 3 was OK prior to being parked for a month, I do not think there is much wrong with it however finding the problem, well that is a big deal. Re the negative battery cable, it is a short little thing; you might want to...

    Diagnostic tool? iLand???

    My comments re post #6 of two years ago still apply. As I said, I have the BlackBox unit but probably the GAP unit is better for North American petrol powered Land Rovers. The major market for BlackBox is Europe where most of vehicles are diesel engine powered and hence BB has a lot of diesel...

    Transmission Fault and more

    Don't give up hope just yet. If it was what I would call the Normally Closed contacts that had dust or arcing, that I would regard as "good" news. Per the attached jpg, the Stop Lamp switch, (S215), NC contacts connect the Antilock Brake Module, (D277). A milliamp signal flows thru those...

    Transmission Fault and more

    You may as well try a hard reset per the instructions below. It costs nothing, does no harm and sometimes fixes computer related stuff. For me, most often it is the radio that is acting up after a battery change out or something where the battery was disconnected, probably before all had gone...

    Radio, water and fun...

    When I have radio problems, (usually after replacing a battery or starter etc that involves disconnecting the battery, I do what is called a Hard Reset as below. It costs nothing; hurts nothing and sometimes works. It is also a stand up clean hands sometimes fix - and yes, it has resolved the...

    All the battery posts got me scared ....

    I have a 2005 LR3 which of course does not have the stop/start feature - thank goodness. I attached the wiring diagram for my 3 and wondered if there was anything I could disconnect to kill the "smart" part of the regulator? I assume if any, it would be a conductor between the alternator and...

    All the battery posts got me scared ....

    I really enjoyed reading that link. Gee guys, we have a problem - there otta be a law! The article would be funny if it were not true. I am led also to believe it will be so good when vehicles drive themselves and I guess go where others decide - that would I presume be what happens when one...

    2005 LR3 code P0504 brake switch

    I would agree, and purchase the bulbs from your Land Rover dealer as you must try to get your 3 back to factory spec. Also remove the two backup light bulbs temporarily as they in the extreme, can affect the ABS which is what your problem probably is - well the ABS/Anti Skid is OK, but...

    All the battery posts got me scared ....

    In the past at least, what is normally called the regulator looked at the battery voltage and if lower than some predetermined "set point", would tell the generator/alternator to start making amps with the goal being to raise the battery voltage to the set point. When that was achieved, then...

    All the battery posts got me scared ....

    I am speaking of my LR3 and its battery "charging" system. I do not think the state of charge of the battery much enters into the calculations that the engine computer does - all it worry's about is emissions and controlling them. Charging the battery is last on its programs list of...

    Jack broken

    The people who first drive Land Rovers new do not change their own tyres - in fact maybe never even have a flat as the vehicle usually goes off lease before the OEM tyres are worn out. As such, not a factory concern. Factory concerns are only when there is failure while still under...

    Jacking with air suspension

    In theory yes, but in reality, when being jacked up, the suspension computer realizes something odd is going on and releases air from the system. In theory, leaving a door open or the tailgate down inhibits air release, but my experience has been otherwise. My solution is two jacks, one bigger...

    Jacking with air suspension

    There is the argument that it makes sense to Land Rover. These are the people who put the steering wheel on the wrong side on some of their vehicles. This is also the same group that cannot figure out they already built the "new" Defender; they called it the Discovery Commercial - coil...

    2011 LR4 Trailer Reverse Sensor

    Below is a PDF file I made up with a material list to make up a suitable LED adapter for my LR3; should work OK on an LR4 as well. https://www.disco3.co.uk/gallery/displayimage.php?album=4497&pos=10 This is a link to the main file related to the trailer connector circuits, both four pin and...

    Jacking with air suspension

    The full size spare was offered as an option on some upgrade package. Part of the excuse for the donut was ground clearance. For what it is worth, the full size tyre hangs down a couple of extra inches relative to the donut.

    Jack broken

    First off, my view is the factory jack should never be used on a Land Rover - they are too heavy. Second, if you are really serious about "something should be done", you submit the broken jack to your "National Transportation Safety Board" and maybe, just maybe, with lots of followup, a recall...

    Jacking with air suspension

    Bottle jack under the A arm - least worst procedure. I carry one of those cheap plastic 12 volt air compressors as my first defense against having to change a flat tyre. With luck, the leak is a slow one and if you pump up the tyre to say fifty pounds, you can drive for a half hour or more and...

    2011 LR4 Trailer Reverse Sensor

    On the 3, if there is not an option included and hence no button included for whatever, then the button location remains but it is hard plastic in that location instead. I still think there is a button to turn off the backup sensor. If so, it self cancels at every engine shutdown and has to be...

    2011 LR4 Trailer Reverse Sensor

    Does your trailer have LED tail lights? I have an LR3 with the official LR harness but Atlantic British should be OK as well. Assuming the LR4 is the same logic setup as an LR3, when a trailer is sensed by the car computer, the backup sensors are disabled. The way the 3 senses that a trailer...

    How crazy would it be...

    That looks better than I thought it would be. Probably one could have stayed with the LR air inlet and filter etc and it would even have looked more stock; also could do the snorkel thing then if one wanted. At least the alternator is where you can get at it - that is a real improvement. Am I...

    How crazy would it be...

    It occurs to me that if one got something like the Ford Raptor pickup engine, the odds are at least the rear of the engine would fit the ZF tranny. It seems that the Ford automatics are license built ZF units. I also expect that many of the sensors on the Ford engine will be the same shape /...

    How crazy would it be...

    It you had the Christmas Tree and the 3 or 4 still would run, that impresses me. I guess that if none of the Land Rover computers are connected to the fuel go and stop systems, then I guess I could understand, but that would suggest that the antiskid programs and whatever else the LR engine...
