8v (which is higher than most). 7v when the alternator is running but it seems to settle around 13v+. 24th Nov 2014 9:07 pm. 2016 D4 Landmark (Written Off)-GONE. On my journey home about 2 mins into it "Charging System Fault" comes up. 65V on the start/stop battery (with engine running). Last edited by promitheus on 23rd Dec 2014 8:57 am. Alternator goes to full output not long after start (a few seconds) and pushes out almost full power at idle. That's very interesting LT! The parameters on the module weren't configured properly. The problem is that the smart charging system calls for power to charge the battery when it's required. Reasonably new battery in rude health: About 10 seconds after starting: About 40 seconds after starting: Apologies for the poor photo but about 60 seconds after starting as shown on a cheap 12v cigar socket voltmeter rather than a Fluke: The above are pretty typical for a D3 with a good battery and good alternator. The TSB is LTB00667 v2.
Location: ¯\_(ツ)_/¯. Will let the dealer know at my first service (12 months that is) in two weeks time. If the voltage stayed fixed I would be wondering what the ECM was doing to regulate the alternator. 89V reading is achieved pretty quickly after I start the engine. That's after 30 mins of travel. And since mine must have been one of the first MY14's, I guess the TSB must concern me as well. Put it down to a lot of start/stops with an undercharged battery. Location: South West. Car had not been driven for a day and temp was about 9 deg C, although it was a little colder overnight. So there have now been a couple of TSB's to rectify this. Charging System Fault [SOLVED]. I was doing short journeys, I had parked up for about and hour left the car and come back to drive home. So I was using it today and it was very hot so I had the air con on and using the cooled seats.
Will try to get a continuous read-out while on the move tomorrow and let you know again. 2016 D4 Landmark (Surely the last! ) Dealer applied technical bulletin LTB00667v2 and everything seems normal, never had the system charging fault since then. After testing the battery and hooking up his laptop thingy, it said it needed a new software download. I had the second version downloaded and it's been fine ever since. Hi everyone, I now have 14000km's on the clock and just got a 'Charging System Fault' error on my display three time during the last couple of months. 23rd Nov 2014 7:43 pm. If the output is variable, not stuck at max and not too low then so far it sounds ok. What I do not have much experience of is dual battery set-ups and these can add an extra dimension. 2006 D3 HSE (Original & still the best)-GONE.
2015 D4 HSE (A heated what? Any help will be welcomed. It appears out of the sudden with the battery icon and red exclamation mark while traveling and stay there for one minute or so, then dissapear.
VINs affectd are MY14's 698741-726591. The car went into limp mode for the rest of the journey. After a C-Tek charge I never saw it again. The details below are for a D3, so the alternator output will be different on a D4, but it gives you an idea. Has anyone had any experience with this? Any suggestions and advice greatly appreciated!
2014 D4 HSE (Almost too bling)-GONE. I have checked the battery and charged it up with my CTEK, but the message appeared again after a few days again. I had the above warning in October when driving to Bristol airport to catch a flight.
