post much appreciated
I much appreciated your post and your comments regarding software.
I have wondered if the other manufacturers such as BMW and Mercedes have as much trouble as Land Rover seems to have. Somehow I cannot imagine that the others have it all figured out and LR does not, but I do wonder.
I question who writes the software? Most of the vehicle subsystems are manufactured by the likes of Magna or Denso and I presume they also write the software for their products.
In the case of ZF, I presume the tranny software is ZF written and then modified by either ZF and/or the auto manufacturer. As such, I presume neither assumes responsibility but just blame each other for problems - an accepted capitalist business model.
What I am saying is there is not much hope for owners.
I have noticed in farm and also construction equipment, the trend seems to be for the end user to just rent/lease the stuff with the deal being that the manufacturer solves all problems and the usual solution more often than not is for the manufacturer to haul out replacement units.
The vehicle manufacturers seem to regard leasing as their solution with the inferred reasoning that true vehicle owners are an anachronistic nuisance that they can afford to ignore.
Regarding the dealer and software installs or more correctly, the unwillingness to install software has much to do with the flat rate system. As we well know, software installs are very much hit and miss, as does the dealer tech, who only gets a minimal number of minutes assigned to the task and zero minutes for re-installs. Also my experience is that there is no real assurance that the software you have attempted to install did install properly, only that it installed or not.
Also it seems that at least on my 2005, there is no actual updated readout of the software installed, only what the factory first installed.
Regarding the radio sort of fixing itself after having disconnected the battery for a few minutes, I have had some success with a variation of that - what some call a hard reset. Below is a summary of the procedure.
Hard Reset Instructions
In brief, to start the hard reset process, open the hood but close all doors and let your 3 go to sleep - no radio display etc and no key in the ignition. This will take a couple of minutes and do not open any doors until the reset is completed. (I find that it is often a good idea to have the driver’s door window rolled down and the key in my pocket whenever fooling about the vehicle.)
Also when I play with a car battery, I remove any rings I have from my fingers, also my watch.
Disconnect the ground battery terminal from the main starting battery.
Disconnect the positive battery terminal from the main starting battery.
The reason for this order is if a wrench or loose battery cable ends grounds to the body, no arcing or other bad things happen.
(I assume that you only have one battery in your 3. If not, disconnect the others as well and leave them disconnected until after all is done.)
Connect the negative cable end to the positive cable end. (NOT the battery.) To do this, you will need a short length, (a foot or so), of light gauge, (14 to 18 gauge AWG, insulated stranded copper), wire to span between the battery cable ends as there is not enough slack in the positive and negative battery cables for the ends to touch each other.
Hold all together for about a minute or more, (at least two minutes), as you are discharging memory modules within the engine computer and elsewhere. Then it is suggested you then just let all sit disconnected for say ten minutes, (minimum five minutes), prior to commencing to put the battery cable ends back on the battery posts per the following order.
Reattach positive terminal to the main starting battery positive post.
Reattach negative terminal to the main starting battery negative post.
Start engine and hopefully none or at least fewer warning lights and the radio when turned on plays music rather than being silent.
Reset time on the radio - note that the station presets are still there as not everything is erased. Nothing much else needs resetting either.
You can also now connect up the other batteries if you have a multiple battery setup.
