Wooohooooo (ish) Fixed but also now Boxer engine management light is on :-/ (1 Viewer)

Right so for a while now Ive known something wasnt right with the fogstar 300ah and it's charging but it was fine when travelling as we rarely stay anywhere for more than a day so the alternator was charging it up fine.
So, yesterday went to move the MH (only a car parking space length for the neighbours convenience) but it was a no go! Power, but wouldn't turn over! Annoying as I've a battery master fitted too!
Long story short - multimeter showed cab battery at 11.9v, so decided to change solar controller to charge cab battery only for 24 hours and bingo today. Also sussed out what was wrong with the solar charging to the Hab battery, simple 15amp fuse! Should have sorted that ages ago!
But now, as in the video below the engine management light is on :-( Thankfully alternator seems fine as charging at 14v.

Some googling seems to indicate I'll need a scanner to reset engine warning, some states disconnecting the cab battery for 15 mins will reset the system, some seems to indicate just drive it 15 to 20 miles and it'll reset itself?
Anyone have any thoughts? Boxer engine 2.0 diesel 2020 Bailey Autograph.

Nobody at all?

Isn't this a known symptom of letting engine battery drop very low ?? You lose airbag sensor or engine management light illuminates? Can be a costly airbag reset by specialist like carcrashdata or similar? Best get OBD scanned.

I don't know if it's a common thing or not to be honest, couldn't find much online about it, was hoping someone here might know :-/

You need the code reading as it could be anything, ps it doesnt look like the airbag death light

Have you tried the Bailey group on Facebook? I don’t do FB but my better half does and there is a lot of useful stuff there. Precisely, the group is The Bailey Motorhome Owners Group.
Hope this helps.

thanks all managed to reset it today as go impatient.
I disconnected pos and neg on the cab battery, left it 15 mins and put a spanner to the ends of the 2 leads OFF the battery.
Put all back together and it was still there, so as all i could find about resetting teh oil light online with the key and the brake / accelorator I tried the same, still no go, tried same again but with clutch and brake and its reset!
