Auxiliary battery malfunction
I've had "Auxiallary Battery Malfunction" on the dash for a good 4-5months now and only just manage to get around and fix this. Ordered the part from A2059052809 Auxiliary Battery Voltage Converter (xenons4u.co.uk) arrived real quick.
Located in the passenger side footwell remove the plate under the glove box, pull back the carpet and then remove the back plate you will find the part.
replace the part put back together and you should be all good.
Tools required
T15
sockets
10mm long
8mm short
no diagnostics required.

Hi, I'm having same problem. We replaced the main and the aux but assuming something is either draining or not charging the aux. Do you know what wire was replaced that fixed this? Also, the trickle charger would be just to avoid the main battery from dying, right? Thanks!
