Hi All,
It doesn't look like there is any cables/wires from the DBS to the negative on the main battery. see pics
As for "does the car reset". It didn't reset the first time it happened, just prior to sending it to LR Service.
Yesterday, it did not reset immediately, however this morning. I started the car with NO engine warning light present. I drove the car approx. 6kms and it seems ok ATM.
My wife mentioned that the first time it happened we were driving and the rear tailgate (top) was not closed properly (we stopped to close it), and yesterday we opened the rear tailgate to put a parcel in the back, whilst the engine was running. Obviously i dismissed my wife comments :D But could this be the one in a million things she says have some relationship to the issue?

Update: Drove another 10kms this morning and engine has gone back into Limp Mode: :(

Hi Brad and first off, you might try temporarily disconnecting the dual battery setup and try a hard reset, then try another drive.
If everything seems OK, without turning the motor off, go and open your tailgate.
If the D4 goes back into Limp Mode, as others have suggested, you may need to check all your cable connections.

Hi again Brad and just out of curiosity, if you don't mind, how much did they charge you for that setup and what did you get?
-
Hi again Brad and sorry, I forgot to ask the obvious.
Do you have a digital multi meter?
If so, take some voltage readings at your cranking battery both before and during a limp home episode.
There is actually a D4 software issue that could cause the same outcome.

Hi Drivesafe,
The Redarc system would of cost me around $1400 (fitted), however i bought the winch, bullbar and snorkel at the same time and had it all fitted together, so got a bit of a discount.
The setup entailed all the DBS (incl battery) with an anderson plug to the rear to connect a solar panel and an extra 12v outlet for fridge etc.
As and FYI, i do have one of your systems in my garage (i never installed it). If you really have to ask ... i was too lazy and was going to on sell it, which btw i never have. Might use it in my next car :)
I do have a multi, so will take some readings and post them up.
-
OK Brad, see if the voltage goes over 12.2v or if it sits around 12.2v.
As posted, there is a known software problem where the alternator is working but the BMS control of the alternator's voltage gets stuck at 12.2v.
I have also set you a PM.

Sorry for those that have read this too many times, but do you have rear air-con Brad? A link to the thread below or the following extract. Hope you sort the issue soon.
"What he (the tech - my newest best friend) found, was where the rear a/c unit is located behind the left cargo space panel, a cable loom that runs under the a/c unit was being squashed and rubbing on the metal body, wearing through the Canbus cables and intermittently shorting to earth. He has moved the a/c unit slightly higher, put some of that door seal strip over the panel joint edge and insulated the worn/cut insulation. Car was cleaned and I was just as excited to get her back as the day I picked her up. The report will be sent to LRA who will most likely include the cause for diagnosis of future similar issues, but for any MY14 owners out there with rear a/c, keep this in mind if you ever lose your dash cluster, stereo, a/c, windows and door locks." or other weird electrical faults it also seems!

Similar to Mungus' post re wire abrasion, I would also have a look under and around the aux battery tray. There are wiring looms close by that may have been rubbed or cut. But not sure if your symptom would be caused by such a shorting issue.

Update: The car has been running fine the last few days. I've done approx. 60kms of testing and the car drives as normal.
I did test the main battery this afternoon after it had been sitting idle for 4 odd hours, and it was at 12.37v.
Could it be the main battery (2yrs old) is on its way out and the aux battery is topping it up over time? The aux battery was at 12.7, noting I had a car fridge connected; was wanting to see if the DBS was draining the main somehow.
I'll test the main again in the morning.
I do not have dual aircon. But I did notice some premature wear on the Anderson plug wire loom that runs to the rear of my car. Taped it up as a precaution.
Planning on a day trip tomorrow around Lithgow, if it's going to fail again, that's the time it will �� Oh well, who dares wins.
