Arkana Window Regulators Fail After Battery Change

I have an Arkana too, and I had a similar issue after disconnecting the battery. Did you try the reset procedure where you hold the window switch up for a few seconds after the window is fully closed?

Yes, tried that multiple times. No luck. Also tried disconnecting the battery again, hoping for a reset. Still nothing. Could it be a deeper electronic issue?

Sounds familiar. I struggled with that reset procedure for ages, then ended up taking mine to a workshop. They sorted it out quickly. Could be a software thing perhaps? Better safe than sorry, wouldn't you agree?

Thanks for the confirmation. I suspected as much. Booked it in for diagnostics; ended up being a full regulator reset. Cost me 290€ but at least it's sorted. Appreciate the help!
