Righto, moving on from my battery drain issue, I have replaced the battery (again) so it's not that at fault but I have every single module failed in the car according to it but also, everything works just fine(ish).
I could list all of the faults out but you will die of boredom scrolling through so here's a taster:
ACM-Audio System
I don't have a parasitic drain on the battery and although it was only just over a year old, it wasn't healthy so that and the alternator have been replaced. I've checked earths etc. but I no longer think it's a voltage issue per se, it feels more like it's a Canbus issue (or whatever the 2010 L322 runs on). I could almost ignore it if I didn't get the suspension warning as I may have had this issue for months but not known about it until now.
Any ideas where to start? I feel like something is killing the canbus but I can't think how to find the culprit and equally I don't want to convince myself this is the issue and go headlong down the wrong path. Have any of you seen this before?
