My family recently purchased a 2008 XC70 with 107k miles and I’m here to hopefully help along the way.
I’ve ordered new ignition coils and spark plugs for probably overdue maintenance, but is there anything else to look out for particularly?

The car runs great, only issue is the driver’s side door loses power *only when shut*.
I read online that it’s probably the wires in the A-pillar and that adding an inch or so of slack will help.

If anyone has any help or ownership advise in general I’m all ears!
An absolute pleasure to meet y’all and thank you.
