Seeking Advice for 2014 Volvo V70 Diesel Cold Starts and Weak Battery Issues

Hey, Just from your description, it sounds like your suspicions might be right. I had something similar happen to me with my 2017 Volvo S60. Wacky cold starts and weak battery during starts as well, annoying as you like. Turns out it was indeed the battery sensor's microprocessor which went defective. From what I learnt, it's a kind of common issue in diesel engines of Volvo models around that range. Frustrating, but nothing to be too alarmed about. They had to replace the entire battery sensor in my case, since fixing the old one was more trouble than it worth. For handling this with your mechanic, I'd suggest just taking it to a trustworthy garage. Tell them your symptoms and your suspicion about the sensor. They'll do a diagnostic and confirm whether it's the sensor or something else going haywire. Anyway, let me know how it goes and best of luck with it! Cheers!

Hey, Greatly appreciate the insight, really reassured me a bit there. So, the bloody sensor it is then! Your experience matches mine pretty closely. I'll definitely follow your advice about taking it to a trusted garage and mention my sensor suspicions. Just out of curiosity - and if you don't mind me asking – do you recall roughly how much the whole sensor replacement set you back? Also, since they fixed it, have you had any more issues, or has it been smooth sailing? Cheers for the help, talk soon!

Hey there, So, about the cost - mine didn't leave much change from a €320 note. My mechanic charged me precisely €315 to swap out that pesky battery sensor microprocessor. Yeah, not exactly chump change. But considering the headache it was causing, well worth it to get my trusty Volvo back in shape. Oh, and since the fix – smooth roads ahead. Not a single hitch since that sensor was sorted out, hands down one of the best €315 I've ever spent. Cold starting issues and all, gone! It's like driving a brand new vehicle, I'm telling you. No worries at all, anytime you need a bit of car banter just hit me up. Hope the fix works just as well for you and your V70! Catch you later, and good luck!

It sounds like you're experiencing cold start issues with your Volvo V70 2011. Since you've already replaced the battery and glow plugs, the next thing to check could be the fuel system. It's possible that the fuel is not being delivered efficiently when the engine is cold. This could be due to a faulty fuel pump, clogged fuel filter, or issues with the fuel injectors. I would recommend having a mechanic inspect the fuel system. If the issue persists, it might be worth checking the engine control unit (ECU) for any fault codes. Please keep us updated on your progress. Do you have any other questions?
