Seeking Advice on Electrical Faults and Battery Issues in 2010 Diesel Volvo S60

Hey folks, I've got a bit of a head-scratcher with my 2010 Diesel Volvo S60. I've been noticing a few quirky things like general electric faults, stored faults showing up, and dim or flickering lights. Even the battery seems weak when starting the engine. I was thinking it might be something to do with terminal 30 interruption, but I'd love to hear if anyone else has experienced something similar? Any tips or suggestions on how to tackle this? If you've had this resolved by a professional, what was your workshop experience like? Any help would be a lifesaver! Cheers.

Hi there! I've been through something similar with my Volvo S80 2012. Let me preface by saying that I have a smidgen of car experience, mostly from dealing with my own vehicles. I suspected a similar issue with terminal 30 but after a visit to my local mechanic it turned out to be a defective battery and it was also pretty discharged, go figure! Cost me a cool 290 Euro to get that sorted. Trust me, an aged or defective battery can cause all sorts of electric gremlins. I'd recommend you to check your battery health first, or take it to a good workshop. With faulty batteries, sometimes it's a matter of replacing them, sometimes they just need a good charging. Every case can be a bit different. By the way, could you tell me some additional details, like mileage, last service, any recent repairs etc.? Might be able to give more precise advice. Good luck!

Hey there! Appreciate the advice. My car's clocked up about 120005 KM. The last service was a good while ago, but the mechanic didn't notice anything glaringly wrong then. Haven't had any major repairs recently, it's just these mysterious electric faults cropping up lately that's got me stumped. Guess I'll follow your lead and get the battery checked first. Fingers crossed it's nothing too severe. Thanks again for your help! Cheers.

Hey! No worries, glad I could help. Given your mileage and previous service history, it sounds quite plausible that your battery might be acting up. Sometimes, mechanics overlook the battery health on routine inspections if the car still starts okay, but our lil' electric friends can start misbehaving especially around the 100,000 KM mark. And ah tellin' you, these gremlins you've mentioned... they do sound battery-ish to me. If you've not replaced your battery in a while, it might be about time. I wouldn't stress too much about terminal 30 as of now. I've been wrong before, but battery-related issues can manifest in surprising ways, as I've learnt from my own experience. I'd say, take your S60 to a professional and get the battery checked (or replaced if needed). Starting off with simpler solutions sometimes works wonders. Do let me know how it goes. Good luck!

Thanks a bunch for your input! Really appreciate it. You're right, haven't replaced the battery in a while, so that could be it. I'll definitely get the battery checked out and will post an update once I have it sorted. Hopefully, that'll put an end to these pesky electrical faults. Cheers for the advice!
