This is a long post, sorry everyone, no 5 second sound bites here, but hopefully some good information.
To all who have an interest in this matter, we have now concluded by many REAL and extensive electrical tests that the second battery system we have on our DISCO 4 cannot possibly have ANY effect at all towards an "Engine Systems Failure" warning, which you may recall caused a serious and dangerous loss of power, even AFTER the Q093 update.
We have conducted many electrical tests, but in this forum, they include a comprehensive set of checks in conjunction with the manufacturer of that second battery system, and those tests as well as the others ALL return zero possibility that an Engine System Failure can be possibly connected with that second battery system. Other professionals in the electronics and electrical industry concur.
So, gals and guys, if you have this problem, don't let some desk clerk trained in repelling warranty claims tell you some BS story to get you to go away. Don't let modern "customer dis(sic)-service" sell you a pile of garbage. Ask any Electronics or Electrical Engineer at any University (get someone independent, not me) and I am confident you will get the same story. Stand up for your rights!
More later on that, as it will all be resolved at some stage, regardless of the method. I will not let this go away until the truth is out!
However, the story continues. I still have computer problems after the last minute Power Control Module update LRA did several weeks ago. I am sure that update (NOT the disconnection of the second battery system) is very likely to have fixed the power loss problem (we still have more checking to do there to verify that, but that checking is now back under way, and 40% complete). Stick to your guns with this one if you have the same problem, get the PCM upgrade and do not accept the vehicle until you have the proof this is done. Do not accept the vehicle back until you are given a copy of the vehicle "feedback" file from the computer which describes the vehicle condition including any error codes in everything which led up to the failure. You can open it in Windows Notebook, but the error codes need translating, I may now be able to help you with that translation.
My advice says you are entitled to that information, so demand it! In fact, my advice suggests you are entitled to that information after EVERY service, regardless of the situation, and it is a very important part of your resale value for any "fly by wire" vehicle. So, I suggest you demand it EVERY time you have your vehicle serviced.
But, back to my problem.... Now, we have an intermittent "Smart Key not found" error immediately after that PCM upgrade. LRA have chosen to ignore this problem for more than 3 weeks!!!!! Not a whisper of a reply. One wonders why this problem would appear, as the Smart Key also has little to do with the Power Control Module. So, why did this happen? I can only surmise.. Why the lack of response? Maybe I need to surmise some more... More on that later too, as the facts reveal themselves......... (Yes, indeed)
So, will I go away? Not a chance. This, I believe, is firstly a safety problem with those who have not had the PCM upgrade and are towing something over about 1500 kgms and secondly it is one going to the core of true client service. I believe I have been advised incorrectly by LRA from the beginning of this problem, and I will not "go away". LRA GM, we know you are on here, but are you listening? I am sure you know who I am and my telephone number.
This is a problem with people who are supposed to fix problems. The vehicle is good, as I have always said. But, LRA seem to be unable to respond properly to fix problems. This is a staffing and sub-contracting problem! Unfortunately this problem goes all the way to the top, the General Manager of Land Rover Australia. That person has decided (maybe I should say they have "determined" if the monitors of this site know what I mean) they will not respond either, even after addressing them (he/she) directly.
Too much Chardonnay in the "behind closed doors" boardroom maybe?. Maybe there isn't a GM......??? Who knows in "modern", "customer service", "open door", management "systems"? It has been more than 3 weeks, they seems to be ignoring their warranty obligations...
One out of left field while I am at it - does one not wonder why the price of these vehicles has not changed at all, even though the exchange rate has improved against the pound in leaps and bounds since the local price was first "determined"? Maybe more Chardy is needed in Epping! Maybe someone should start a thread on this one! Over to someone else who feels the prices should not be where they are given the exchange rate.
When one buys a vehicle, warranty is part of the package, or the supplier says it is, but LRA seems to be having problems supplying that essential parameter. Maybe they need appropriately trained staff!! I don't know, but I believe LRA support is not working as it should be now. So, get to know your dealer and support them as much as you can in the search for real and meaningful information from LRA - that is my suggestion! You pay $100,000 for a vehicle. One of the expectations is that you get commensurate service. I have personally not seen any evidence of this from LRA, (I exclude the dealers from this view, as they (seem) to do what they can in a difficult situation)
I stress, this does not appear in any form to be a problem of any of the dealers technical staff, I have submitted our problem direct to LRA, as this new "Smart Key" problem appeared only after work LRA technical staff themselves are "supposed" to have done on our vehicle to fix our power problem All they seem to have done is shift the problem to the Smart Key recognition. The continuing answer is silence, and I think will remain that way until some sense is injected into this discussion. Maybe others outside LRA with real investigative responsibility need to know about all these dangerous power loss problems. What does everyone out there think?
