I did have a search to see what I could find on here and it seems that this error, likely/possibly correlates to the battery in the front being knackered? So I got myself a replacement battery. The main one was changed last year and although I know that sometimes needs a charge due to only mainly using the car every other weekend, it's been fine. Reassuringly expensive The only thing is, I've started the car and the error is still there. Does it need plugging in so the error can be cleared? Is there anything I can do to reset it? I believe the auxiliary battery was the original one so pretty old. Just annoyed the message hasn't gone. Have I damaged something trying to charge the rear battery? :wall bash: Any advice, greatly appreciated.
