V40 passenger electric seat issue

My 2013 Volvo V40 diesel has developed a fault with the passenger electric seat. There's an error stored and seat adjustment isn't possible. Diagnostics point towards a discharged or defective battery. Has anyone seen this before?

Sounds familiar! I had a similar issue with my old BMW 3 Series. All the electrics went haywire because the battery was failing. Electric seats can be super sensitive to voltage drops. Have you checked the seat wiring and harness for damage?

Thanks for the heads up. I checked the seat wiring and harness, all looks good. Were you able to fix it yourself or did you bring it to a workshop?

I poked around a bit with a multimeter, but electrics aren't my strong suit. I ended up taking it to a mechanic. They confirmed the battery was the root cause and replaced it, and everything went back to normal. So you might need a new battery.

Appreciate the insight. The battery was indeed the issue. Replacement and labor cost 290€. Hopefully, this thread helps others.
