Check the fuse at the main battery end, I think it's under the battery, or more easily remove the charge relay and check it has voltage on the feed from the main battery.
Help! No more electricity from the alternator? Or something else?

If you do not have the starter battery voltage at relay "100" connector - the next to check is the main fuse feeding second battery circuit - under starter battery fuse SA3 (100Amps) - number 3 in the picture.

Oh no....
It was just this, this unplugged cable.
I tried and it's working now.
I'm sorry for the lost of time (at least I learned new things). I hope this topic will help some people.
Too busy with my clients + trusting the job done by the garage, I didn't check, not thinking it could be this kind of thing...
Thanks a lot for your help.

That would explain it. If the BCM can't monitor the battery it will be very careful with load and clearly doesn't engage the split charge relay.
Hi All, I Have what I believe is the same fault but wanted to run it by a few more experienced people before buying a new alternator, our van is a 2017 T6 Ex RAC, It stands a lot as we have converted to a campervan and after a few days away we were about 15 miles from home when the battery light came on, we have a Renogy 50A DC to DC Charger with a solar panel and a 100Ah Renogy house battery, The starter battery was replaced about September last year and coded so I'm happy that all that is okay.
Here is the fault code from VCDS and I have attached a couple of screenshots and have also checked that the belt is there and going round as it should, thanks for any input on this?

Quiescent limit.... Referred to your loads pulling more than 50mA off the starter battery when the van is sleeping.... Normally a dash cam m or usb charger etc.
The other alternator fault, had a fault count of one... So note the fault code, clear the code and carry on.... If it comes back we can take a better look.
Id it comes back there are a few places to look.

The VCDS screenshots show that generator is not working. Requested voltages 14.3 and 15.0 but battery remains at 11.456 V. Also generator current stays at 0.0 A, as well as exciter current 0.000 A - assuming engine was running.
For a working good VCDS example see post #3.

Hi! I'm stuck with my clients, fault on the car. I have a Caravelle T6 from 2016 July. I was driving last night when the red light came (battery logo on the dashboard). I used my bluetooth OBD to check : 12,2v when engine running, to 11,7 then I stopped the engine. I checked the voltage...
Thanks for the reply, yes the engine was running, I will order a new alternator and fit it.The VCDS screenshots show that generator is not working.

I think some places will let me trade in the old one.
Thanks again.
Thanks for the reply, I tried clearing the fault but it came right back, do you think it could be something other than the alternator?
Could the Quiescent limit be caused by something like my DC to DC charger?
I run my dashcam and a 12v socket in the cab from my leisure battery so it shouldn't be either of those.

@Dellmassive & @mmi I also took the attached log yesterday if it helps?
The relevant ones were captured in screenshots in post #32.
Those voltages look normal - but different than controller 61 (battery regulator) is reporting
The logs were done yesterday and the Multi-meter readings were done this evening, I might go back out and check to see if the battery light is still on.The relevant ones were captured in screenshots in post #32.
