2015 Volvo XC70 Showing Black Smoke, Reduced Power, and Erratic Engine Behavior

Hey there, I totally understand your situation as I had a similar issue with my 2018 Volvo XC60. You're right! It very well could be a problem with the ignition coil misfiring or being defective based on the symptoms you've described. From my experience, you've hit the nail on the head. The same symptoms cropped up with my Volvo - unsteady engine, power loss, and poor fuel economy. After doing some research, it seemed like a cable connection to the ignition coil was the issue. Took it into the garage and found out the ignition coil's cable connection was indeed defective. Getting the cable connection to the ignition coil fixed led to clearing up most of the problems that you've mentioned. So, your assumption might be spot-on! Remember, it was a bit of a serious issue and needed immediate attention to prevent potential long-term engine damage. I hope it helps and your car gets back to its smooth running self soon enough! Cheers!

Hey, Wow, that's a real relief to hear I might be on the right track! It's always anxiety-inducing when you have car issues, right? But you've given me some peace of mind for sure. Just out of curiosity, do you remember how much it cost you to get that ignition coil cable connection issue sorted out? And ever since the fix, did you bump into any other related issues? Again, thanks a ton for chipping in with your experience and knowledge, it's been super helpful! Cheers!

Hey, I get the nerve-wracking part of having car troubles, it's a real hassle. If memory serves, the bill to get the cable connection to the ignition coil sorted was around €365. I mean, ain't pocket change, but given it could've prevented potential serious engine damage, it's worth it. I'm glad to report that since the visit to the mechanic, the faulty ignition coil hasn't given me any more trouble, which is a big thumbs up considering the jerkiness and power loss I was experiencing before. My Volvo's been smooth sailing since then! Hope your Volvo gets sorted soon . And remember, a good running car is worth every penny spent on it! Cheers!

Hey, Thank you so much for the info! Yeah, you’re right, that's a fair bit of money, but as you said, any cost to prevent further damage is genuinely worth every cent. It's really encouraging to hear that your Volvo has been running smoothly afterwards. That gives me hope that once I get this fixed, mine will be back on the right track too. Your advice and experience have been incredibly helpful! I now feel more assured about taking my Volvo to the mechanic. Here's hoping my mechanic experience this time turns out better than the last one. Thanks again for all your help! Cheers!
